The Pragmatic Engineer's Career
How to navigate your software engineering career from junior to staff and beyond.
Key Insights
Career growth is not linear — it requires deliberate decisions about specialization vs. generalization.
The jump from senior to staff engineer requires a fundamental shift from individual output to organizational impact.
Visibility and communication matter as much as technical skill at senior levels.
Notes
The Career Ladder
Junior → Mid → Senior is mostly about technical competence. Senior → Staff → Principal is about impact, influence, and organizational thinking. The skills that got you promoted to senior won't get you promoted to staff. You need to develop new muscles: strategic thinking, cross-team collaboration, and technical vision.
T-Shaped Engineers
The most effective senior+ engineers are T-shaped: deep expertise in one area with broad knowledge across many. This allows them to be the go-to expert in their domain while still being effective contributors across the stack.
The Staff Engineer Trap
Many engineers get stuck at senior because they keep optimizing what made them successful: writing more code, faster. But staff-level impact requires less coding and more: writing design docs, mentoring, influencing architecture decisions, and identifying the right problems to solve.
Building Your Reputation
Write internal blog posts about your learnings. Give tech talks. Document architectural decisions. Share post-mortems. These activities compound over time and build your reputation as a technical leader.
Quotes
“The most impactful engineers I know spend as much time thinking about what NOT to build as what to build.”
“Your career is a marathon, not a sprint. Invest in relationships and learning — they compound.”
