What software engineer postings actually require
- Experience: median 5 years where stated (182 postings specified a number). State your years explicitly — "7+ years building distributed systems" beats making the recruiter count your dates.
- Degrees: only 1.6% explicitly require one (12.7% mention one at all). If you have a degree, list it; if not, lead with skills and shipped work — the data says that's what most postings now screen for.
- Work mode: 12.6% mention remote, 14.9% hybrid, 7.9% on-site language. Mirror the posting's location language in your resume header if you match it.

How to use these keywords without keyword-stuffing
Recruiters search their ATS for literal strings, then read the bullets around the match. So each keyword needs to live inside an achievement: "Built CI/CD pipelines (GitHub Actions) that cut release time 60%" works for both the search and the human. Put the highest-frequency terms in your skills section and at least one experience bullet — placement rules are in our keyword placement guide, and the full tailoring workflow is in how to tailor your resume to a job description.
