Executing projects that have significant influence and complexity.

Upon attaining a senior position, the expectation evolves beyond simply possessing software development skills to include broader aspects of the field.

Drive key initiatives to their successful completion.

In many large tech companies, engineers who have progressed beyond the entry-level position frequently take charge of projects even though they may not be formally designated as "tech leads." Managing projects involves taking on duties commonly shouldered by project managers, such as allocating tasks, defining clear roles, and coordinating the contributions of different team members. In his discussion on management, Orosz underscores the necessity of initiating projects with well-defined objectives. Under what conditions and at what time?

Demonstrate the ability to break down complex problems, identify risks, and devise pragmatic solutions

The duties of a technical leader involve breaking down complex issues into smaller, more manageable tasks and distributing them, while senior engineers are expected to confront complicated issues head-on. To develop this expertise, significant personal development is required, achievable through careful observation and imitation of approaches used by experienced individuals, like a technical leader or an engineer. Start by thoroughly analyzing the problem, identifying the necessary actions, and recognizing potential hazards. Gather perspectives by soliciting views after distributing all the relevant information. Consult with a seasoned professional in the pertinent area or set aside a designated time for exploratory study to bridge the knowledge deficiencies you have.

Juggle and effectively handle various competing tasks, guaranteeing prompt completion while maintaining high standards.

The author highlights the challenges that senior engineers face when they have to prioritize and handle a multitude of incoming requests. Gergely Orosz advises adopting a two-pronged approach to handle new tasks: saying no or passing on tasks that are urgent but not critical, setting aside time for important tasks that don't demand immediate action, and promptly tackling duties that demand immediate attention and carry significant weight.

Make certain that your attention doesn't appear to be exclusively on tasks of personal importance, regardless of their significance. It's essential to be regarded as someone who collaborates well with others! If a team member is considering leaving the group, it would be beneficial to postpone your own work to offer support. It's essential for the overall good to establish limits if you find that your attention is often diverted from the work you're supposed to be doing. Work alongside your colleagues to devise a plan that effectively handles incoming requests, ensuring that team members are not hindered or overly burdened by additional responsibilities.

Advancing within the software engineering discipline.

As a senior engineer, your responsibilities extend beyond the completion of explicitly outlined tasks. Individuals at the senior engineer level and higher are expected to set an example in improving engineering standards by adopting and promoting new methodologies and practices within their team or group.

Champion the adoption of premier engineering practices and methodologies.

In the fifth section, which delves into software development practices, Orosz explores numerous tactics such as scrutinizing code before and after it is submitted, particularly for experienced teams, implementing automated tests, and embracing continuous integration and delivery processes, while also providing guidance on the implementation of these methods and their benefits. Other engineering practices worth knowing and using when they are the right tools for the job, include trunk-based development, monorepos, the microservices architecture, and feature flags.

Grasp the benefits, constraints, and possible hazards linked to each technique, along with their connection to the unique interactions among your team members. Gergely Orosz emphasizes that no single strategy or method consistently leads to success in every engineering organization. He emphasizes the necessity of tackling the inherent challenges within the engineering process and finding methods to surmount them.

It is essential to measure the productivity of engineers against standards like DORA metrics to determine if extended build systems, protracted testing periods, or lengthy review processes are slowing down the production of code. Each bottleneck offers a distinct array of possible remedies. Some can be tackled by the team, such as breaking down large pull requests into smaller ones, and others will likely need input from other teams, or even company-level decisions, like acquiring a tool to speed up builds, or to spin up dynamic test environments for quicker testing feedback.

Ensure the software's core stability by proactively addressing and settling any accrued technical obligations.

The concept of balancing meticulousness in tech solutions with the need to adhere to delivery schedules is encapsulated by the term 'technical debt'. Engineering teams often face substantial costs stemming from extended project durations and seemingly small alterations to the code that unexpectedly result in substantial issues within the system, which can be traced back to less-than-ideal decisions taken in the initial stages of architectural design. It's impossible to avoid all tech debt, but there are approaches for minimizing it, and deciding when to take on debt, with the knowledge of the cost.

Orosz outlines how an engineer's understanding of technical debt begins with a lack of awareness, moves through a stage of denying its impact on the engineering process, and ultimately culminates in recognizing and embracing it.

He also recommends dedicating just enough time and effort to prevent or slow down the accumulation of technical debt instead of investing resources to resolve it later on. Orosz stresses the significance of crafting code that is clear and straightforward to verify, and underscores the necessity for continuous code reorganization to improve its clarity, ensure its ease of management, and diminish the complexity of interactions between the system's components. Focus on improving the software by removing outdated experiments, features that are no longer used, and sections of code that are redundant or not fully developed. Create systems with built-in adaptability, foreseeing possible future needs and designed for seamless enhancement when necessary.

When evaluating the accumulation of unsolved technical issues, it's essential to balance the advantages and carefully evaluate the necessary work to resolve them, as well as understand their impact on the organization. Orosz suggests a creative way to do it: bundle it into large enough, impactful projects that get noticed by the business. Make certain that when you forecast the outcomes of a project that entails complex modifications to a system, you include plans for addressing the significant technical debt within the targeted area.

Foster the growth of junior engineers by sharing your expertise and supporting their professional progression.

In your position as a senior engineer, you are expected to provide guidance, share knowledge with, and support the professional growth of your less experienced team members. There are many approaches for doing so: giving feedback on code reviews, pairing with engineers, guiding them to unblock themselves, answering their questions, and offering career and work-related suggestions.

Orosz explores effective mentorship techniques that encompass encouraging insightful feedback, avoiding the provision of immediate answers, presenting multiple options, and fostering independence in mentees, among other strategies. The most productive mentor-mentee exchanges are marked by a mutual exchange of understanding and perspectives.

Driving Architectural Decisions

In some more traditional companies, individuals may hold the title of architects, but this designation is not typically employed at tech startups or within major technology firms. Engineers who have reached the staff level or higher are expected to have robust architectural skills. Teams frequently fill roles related to architecture even if the formal designation of "software architect" isn't employed. Staff engineers are anticipated to assume this duty.

Create a software structure designed to be resilient and adaptable, which allows for modifications in response to evolving business requirements.

A staff engineer is generally expected to oversee a wider range of duties than what is usually expected of a senior engineer. Your responsibilities and the potential impact of the projects you manage will grow substantially as you advance in your career. Orosz highlights the disparity by illustrating that a staff engineer in charge of a system generating $1 million a year for a niche audience has vastly different responsibilities from one managing a system that earns $500 million and caters to a wide-ranging audience.

Engineers frequently play a crucial role in determining key architectural decisions that influence multiple facets, and their responsibilities involve devising strategies focused on scalability and dependability, as well as taking into account expenses and long-term sustainability. To succeed in this field, one must establish a robust base by addressing less complex engineering challenges at a smaller scale.

In his discussion on system design, Orosz explores how to construct architectures that are built to handle growing demands and scalability. He elucidates that scalability is about adjusting to emerging business contexts and increasing the capability of the infrastructure to manage data, user requests, and operational demands through strategies like resource augmentation across multiple dimensions, segmenting data, caching commonly retrieved data for rapid retrieval, and deploying strategies for communication, as well as setting up systems for data redundancy.

Balance competing priorities effectively, considering factors like system efficiency, safeguarding measures, and long-term code sustainability.

In the practical domain, although systems that can scale, are dependable, and offer high performance are in demand, one must also take into account other vital factors such as expense, timeliness of completion, as well as the team's combined expertise and resources at hand.

Orosz outlines various strategies for informed decision-making in architectural design:

• Start by getting clarity on capability requirements before suggesting implementation. When designing a system, is it more important to prioritize maintaining strong performance during high-demand periods, or to concentrate on reducing running costs? Are both equally important, or are they both inconsequential? Grasping the circumstances surrounding decision-making is crucial. Ensure you conduct a comprehensive evaluation before finalizing decisions that may be difficult to undo.
• Start formulating a preliminary strategy, even if it doesn't end up being included in the final product. Establishing an initial structure can improve the accuracy of your project's schedule forecasts, uncover unexpected obstacles, and strengthen the rationale behind the selected methodology.

Ensure alignment on architectural decisions through effective communication and collaboration with all stakeholders, regardless of their technical background.

Gergely Orosz underscores the importance of prioritizing teamwork to handle communications with involved parties effectively. Prior to altering the system's structure, engaging with stakeholders is essential to avoid superfluous tasks. Circulate a written outline detailing the suggested changes, for instance, a Design Specification, a Review Proposal, or an Architectural Decision Record.

Decisions with far-reaching consequences necessitate unanimous agreement among all stakeholders involved. Occasionally, it might require initiating contact with individuals or teams responsible for particular tasks. The implementation of your updates may require modifications by teams responsible for managing platform infrastructure or systems, and also necessitate alterations by users of a service or API before your new features go live in the production setting.

Other Perspectives

• While senior engineers are expected to have a high level of skill and mastery, it's also true that continuous learning is essential due to the rapidly evolving nature of technology, and mastery is not a static achievement.
• Autonomy in overseeing projects can be beneficial, but it can also lead to siloed knowledge and decision-making if not balanced with team collaboration and knowledge sharing.
• The expectation for senior engineers to independently solve a wide range of complex issues may sometimes overlook the value of collaborative problem-solving and the diverse perspectives junior engineers can bring.
• Deep technical knowledge is crucial, but soft skills such as communication, empathy, and leadership are equally important for a staff engineer role and can sometimes be undervalued.
• Executing projects with significant influence and complexity requires not just technical skills but also a deep understanding of the business context, which may not always be a strength for engineers focused on technical details.
• Driving key initiatives to completion is important, but the process should also include checks and balances to ensure that the initiatives align with the overall strategic goals of the organization.
• Breaking down complex problems is a critical skill, but it's also important to recognize when a problem requires a more innovative approach rather than just a pragmatic solution.
• Juggling various competing tasks effectively is a challenge, and the idea of prompt completion must be balanced against the risk of burnout and the need for sustainable work practices.
• Setting an example in improving engineering standards is important, but it's also necessary to be open to questioning and revising those standards as new information and techniques become available.
• Championing the adoption of premier engineering practices is valuable, but it's also important to recognize that not all practices are suitable for every context and to remain flexible in approach.
• Ensuring software core stability is crucial, but focusing too much on stability can sometimes stifle innovation and the adoption of cutting-edge technologies.
• Fostering the growth of junior engineers is a responsibility of senior engineers, but it should not come at the expense of their own professional development and career progression.
• Creating a resilient and adaptable software structure is important, but it must be balanced with the practical constraints of deadlines, budgets, and existing legacy systems.
• Balancing competing priorities effectively is a complex task, and there can be a tendency to favor short-term efficiency over long-term sustainability, which may not always be in the best interest of the product or the company.
• Ensuring alignment on architectural decisions is important, but it's also critical to allow room for dissenting opinions and alternative approaches that may lead to better outcomes.

Engineering Leadership and Effective Teamwork

As you advance in your profession, the anticipation that you will deliver progressively significant input to the group intensifies with every step up the seniority ladder. There's a common belief that senior engineers inherently understand certain expectations, even if these expectations haven't been explicitly stated. Gergely Orosz's guide underscores the paramount importance of software engineers proactively steering their own professional trajectories.

To become acknowledged as a skilled Senior Engineer, one must focus on two primary aspects.

1. The capacity to effectively address intricate technical challenges.
2. Regularly sharing updates about your finished tasks and achievements with colleagues and those in higher positions.

At staff+ levels, the expectations increase, and it's typically expected that one will not only assist their immediate team but also contribute to the efforts of other teams, and in some cases, support the entire engineering division.

Fostering a team that is strong and operates effectively.

In your role as a senior or tech lead, it is expected that you will nurture your team's development, aid in the completion of assignments, and guarantee the elimination of any impediments. Professionals at the staff+ level are expected to progress in their positions while also ensuring the welfare of their team. What is the true meaning of this?

Cultivate an environment that encourages open communication, constructive feedback, and mutual support.

Orosz highlights the characteristics that distinguish successful teams, including their shared understanding of goals, knowledge of the strategies needed to achieve these goals, steady progress, positive attitude, strong relationships and trust among team members, as well as the presence of dedicated and supportive members.

Tackle team dynamic challenges, such as disputes or signs that suggest disengagement.

A variety of factors can lead to a breakdown in team cohesion, including poor leadership, the impact of a skilled yet challenging team member, a lack of necessary abilities, a deficit of constructive criticism, unclear goals, hindered progress, an excess of information, or too many rigid processes that limit adaptability. In the chapter, Orosz explores the intricate interplay of teamwork.

As a staff engineer, you have the unique chance to identify and address issues within team dynamics, guiding the team toward enhanced collaboration. To suggest improvements, it's essential to first grasp the inner dynamics and interpersonal connections within the group. Reflect on your group's primary assets, pinpoint the current main challenge, and ascertain the single improvement that could most profoundly elevate the morale of your collective. Initiate meaningful conversations by asking questions and listening carefully to your colleague's viewpoint. While it's acceptable not to have a solution for every issue, your role should include recognizing potential problems and ensuring that those needing managerial awareness are appropriately highlighted.

Cultivate an environment within the team that persistently highlights continuous improvement and learning.

Boosting the efficiency of the team's engineering processes is key to preserving its consistent performance and preventing any decline. To achieve this, Orosz suggests regularly reviewing team processes and removing those which are no longer helpful or add little value. How can one characterize an item that holds minimal worth? These processes could be optimized, mechanized, assigned to others, completely removed, or replaced by a procedure that offers greater benefits. Push for removing processes first, and only then consider adding new ones.

Interdepartmental and group collaboration

In the "Collaboration" section, Orosz emphasizes that office politics, also known as internal politics, generally have a negative reputation among software engineering professionals.

He advises against engaging in actions perceived as egotistical, which include excessively pursuing personal advancement to the detriment of team members, showing inflexibility, sidelining peers for personal gain, or exhibiting untrustworthy traits, similar to a "seagull manager" who makes an appearance to impose their opinions and then leaves, passing the responsibility of implementation to others. He considers the skill of influencing colleagues within a company as advantageous, signifying a type of organizational dynamics that can be utilized positively.

Foster robust bonds and maintain open lines of communication among various engineering groups.

Establishing strong, beneficial relationships with different entities and groups before urgent situations emerge can significantly improve efficiency. Orosz offers numerous strategies for cultivating and sustaining a robust network:

• Get to know the various teams. Initiate an informal dialogue with someone from a team you're not acquainted with to grasp their duties. Investigate the advantageous techniques and instruments utilized by the collective group.
• Interact with supervisors from different teams, including engineering leaders, to fully understand their functions and how they fit into the broader structure of the organization.
• Opt for spoken conversations rather than text-based ones when dealing with challenging circumstances. When disagreements arise, take the opportunity to strengthen your relationship with a team member by engaging directly in person or via a video conference. Orosz emphasizes the benefit of verbal conversations in preventing the common confusions that often arise from text-based communication methods such as instant messaging or electronic mail.
• Collaborate closely with leaders from various technical groups. Schedule a session to converse about the progression of the project with those in charge. Participating in these endeavors enhances one's understanding of team dynamics and at the same time cultivates connections that could be advantageous in the future.

Work closely with product managers and business stakeholders to ensure a mutual understanding of the project's goals and significance.

How does one craft exceptional software that meets the needs of users within the commercial sector? Understanding the complexities of what clients require and recognizing how your innovative input can enhance and refine the company's operations is essential. In the segment "Grasping Commercial Insights," Orosz outlines different tactics for understanding the nuances of the industry.

Start by analyzing the results of your team's work to grasp the commercial operations. Understand the product's attributes, comprehend why customers choose it, familiarize with its competitors, and assess how it influences the company's financial stability, following the guidance of Orosz.

He recommends approaching projects with the mindset of a product manager and, where possible, working in tandem with one to lend support in areas that require specialized technical knowledge. When a product manager is not present, a situation often encountered in platform development teams, take the initiative to assume the responsibilities of the de facto product manager.

Grasp your client's viewpoint

Orosz emphasizes the importance of embracing this perspective to thoroughly comprehend the motivations behind a client's interaction with the product. Deepen your comprehension by engaging directly with the software as the end-users do, particularly when your own use is not representative of or is limited compared to theirs. Establish a test account for product registration, engage with user researchers during customer engagements, and carefully examine the questions and answers that come through customer support channels.

Adopt the investigative approach of a sleuth to determine your rivals, their actions, and the comparative quality of their offerings against your own creations. Assess your product's position in the competitive landscape to grasp its standing compared to rival offerings. How do their unique traits differ from your own? What improvements could be made in their handling of distinctive scenarios and user interactions?

Assess how the product benefits the business, whether by generating revenue or by providing an essential service that isn't directly profitable. Examine in detail the impact your product has on the economic prosperity of the company, taking into account its contribution to revenue generation, cost control, acquisition of new clients, maintenance of current clientele, or other relevant aspects. Gain comprehensive understanding of the field or market that your organization operates within.

Orosz underscores the significance of thoroughly understanding the company by examining its business framework and nurturing connections with colleagues across various sectors by engaging in conversations, discreetly joining meetings, and collaborating on projects that span several groups. He also recommends scrutinizing leadership communication, looking for the underlying messages, and engaging proactively in conversations regarding strategic direction.

Utilize your expertise in technology to guide decisions and cultivate outcomes advantageous to the organization.

To make your opinion matter in an organization, you need to build "trust capital," and this is an asset earned over time by having a track record of getting things done, building up relevant engineering and business expertise, being tenured, and ensuring people know about your work.

Gergely Orosz offers a systematic summary of techniques to broaden your influence:

• Listen with heightened attentiveness. Pay close attention to the conversations of your colleagues, the challenges they face, their questions, and the problems they are striving to overcome.
• Inquire actively. Ensure you comprehend the intentions of others by seeking further explanation. People frequently conceive exceptional ideas that you can help develop and realize.
• Articulate your perspective clearly, providing the rationale that underpins it.

Guaranteeing the systems operate at peak efficiency and with utmost dependability.

In the chapter titled "Reliable Software Systems," Orosz points out that at prominent tech firms, engineering teams usually take on the duty of creating and overseeing their own on-call systems for emergencies.

Develop comprehensive systems for surveillance and notifications, and create efficient protocols for incident management.

Engineers at the staff level are expected to improve the reliability of systems, which can involve those operated by their own team or even systems that have a wider influence. Reliability is a huge topic and involves approaches for logging, monitoring, defining alerting thresholds and strategies for when to alert, putting in place an on-call rotation, and defining incident management processes: all covered in this chapter.

The goal of any logging, monitoring, alerting, and incident management system is to make the running of software as reliable as possible, and to help make debugging more efficient when things go wrong. Orosz underscores the necessity of monitoring key metrics such as system uptime, CPU usage, as well as the rate of errors and the speed at which the system responds.

A variety of methods and tools are available to set up a system for managing incidents that aligns with the practices widely adopted by numerous tech companies. Orosz observes that few companies successfully utilize incident management to bolster the robustness of teams and systems by fostering a culture of learning.

Champion the implementation of sophisticated techniques that bolster system robustness, thereby increasing their capacity to manage faults more effectively.

Ensuring robustness in systems under development is essential, which involves establishing metrics such as uptime or response speed. Ensure that the monitoring system is set up to do more than just log these metrics; it should also trigger alerts that engineers are prepared and are indeed responding to respond.

When determining architectural choices, it's crucial to contemplate the outcomes during system malfunctions. What systems will this one rely on, and what should be the response when these systems do not function correctly? The author advises constructing resilient systems that include plans for the seamless reduction in functionality of linked services, along with the implementation of mechanisms for reattempting connections to application programming interfaces and the employment of circuit interrupters.

Consistently improve the reliability of the software infrastructure by analyzing past incidents to gain insights.

Orosz remarks that the technology sector lags behind numerous other fields in the development of dependable systems.

In the event of a system malfunction, tech companies emphasize understanding the systemic flaws that contributed to the problem rather than focusing on the actions of a single engineer. He underscores that the main purpose of most incident reports is to record events, not to enhance understanding or learning.

Orosz recounts an experience where he addressed memory leaks while working at Uber:

The issue arose from the custom-developed ORM tool's difficulty in efficiently managing data volumes that were even moderately substantial. I inquired with the seasoned professional regarding the various options and their attributes. It would seem to indicate. In the course of our conversations, the idea of abandoning the Object-Relational Mapping emerged as a potential course of action. Selecting an ORM tool known for its robust performance would be a more prudent decision. I ultimately adapted the software to incorporate a widely used and esteemed data management tool that employs object-relational mapping.

In your role as a staff+ engineer, your influence extends to overseeing incidents within your team and coordinating response efforts across various teams company-wide. Evaluate situations by emphasizing cooperative resolution efforts instead of attributing fault, and by identifying specific steps to improve understanding and system processes to prevent similar issues in the future.
