Three pitfalls that quietly tank Senior Software Engineer resumes

  1. 1

    Reading like a mid-level resume with more years — show ownership, cross-team scope, and design decisions.

  2. 2

    No mention of mentoring or technical leadership signals — Senior JDs almost always include these.

  3. 3

    Stacking too many tools — the senior signal is depth, not breadth. Pick 6-8 you can defend deeply.
