Software Engineer resume example

Software engineering resumes fail for a predictable reason: they list technologies instead of outcomes. Recruiters screening hundreds of applications look for evidence you shipped things that mattered — latency cut, revenue unblocked, incidents prevented — with the stack as supporting detail, not the headline.

The example below shows the structure that survives both the ATS keyword filter and the six-second human scan: a title-matched header, a summary that leads with scope, and bullets that follow the "did X, measured by Y, using Z" pattern.

Professional summary example

Software Engineer with 5 years building high-traffic backend services in Python and Go. Led the migration of a monolith serving 2M daily users to event-driven microservices, cutting p95 latency 43% and paging incidents by two-thirds. Comfortable owning systems end-to-end, from design review to on-call.

Achievement bullet examples

  • Reduced p95 API latency from 480ms to 275ms by introducing read-through Redis caching and rewriting the three hottest SQL queries — directly lifting checkout conversion 2.1%.
  • Designed and shipped an idempotent payment-retry pipeline (Go, Kafka) that recovered $1.2M/year in previously dropped transactions.
  • Cut CI wall-time from 34 to 11 minutes by parallelizing the test suite and caching dependency layers, saving the 14-engineer team ~40 hours/month.
  • Mentored 3 junior engineers through their first production launches; all three promoted within 18 months.

Writing tips for this role

Mirror the job posting’s exact stack keywords

ATS filters match literal strings. If the posting says "Amazon Web Services", write that alongside "AWS" at least once. Put the matched stack in your top-third: summary or first role.

Quantify even "unquantifiable" work

Refactors and migrations have numbers too: build minutes saved, incident count before/after, services consolidated. A bullet without a number reads as a duty, not an achievement.

Keep the layout single-column

Two-column layouts and skill graphics scramble in most ATS parsers. Standard headings ("Work Experience", "Skills", "Education") parse reliably; clever ones ("My Journey") often don’t.

Frequently asked questions

How long should a software engineer resume be?

One page under ~8 years of experience, two pages maximum after that. Recruiters skim; length beyond two pages dilutes your strongest signal.

Should I list every technology I have touched?

No — list what you could interview on today, weighted toward the target role’s stack. A 40-item skills cloud reads as noise and drags keyword relevance down.

Do side projects belong on a mid-level resume?

Only if they demonstrate something your work experience doesn’t — real users, an unfamiliar stack, or open-source maintenance. One or two strong entries beat a list of tutorials.
