At this point, you're not just writing code—you're deciding HOW things get built. You've seen systems grow (and sometimes break) at scale. You mentor whole teams, not just individuals. Your resume needs to show you think architecturally and multiply the output of everyone around you.

At mid-level, your impact includes team improvement. Show mentoring, process improvements, and tooling.

'Within my squad' isn't enough. Show how you've influenced engineering standards across teams.

Frequently Asked Questions
What's the difference between senior and staff engineer?
Senior focuses on squad-level impact. Staff shows org-wide influence: technical vision, cross-team projects, and multiplier effect on engineering culture.
Should I move to management or stay technical?
Both paths are valid. If you love building, the staff/principal track offers growth. If you love growing people, consider management. Some roles (tech lead) blend both.
