Software Engineer Resume Examples
The biggest difference between a resume that passes ATS and one that doesn't is often a handful of bullet points. Below you'll find 2 real before-and-after rewrites for Software Engineer resumes — from vague, weak bullets to specific, metrics-driven, keyword-rich statements.
What Makes a Strong Software Engineer Bullet?
Quantified impact
Numbers, percentages, or dollar values show the scale of your contribution.
ATS keywords in context
Key terms like "software development" and "algorithms" placed naturally in bullets.
Strong action verb
Opens with a past-tense verb (Led, Delivered, Reduced) — not "Responsible for."

How ATS Screens Software Engineer Resumes
Tech companies run high-volume hiring — a single senior role at a FAANG-tier company can attract 500+ applications. Greenhouse and Lever (the most common ATS in tech) score candidates on exact keyword matches from the job description. Missing a single critical keyword (e.g., "Kubernetes" when the JD requires it) can drop your match score below the recruiter's filter threshold, making you invisible before any human review.
Example Professional Summary
Your resume summary is the first thing ATS and recruiters parse. Here's what weak versus strong looks like for a Software Engineer:
"Experienced software engineer looking for a challenging opportunity where I can utilise my skills and contribute to the growth of the organisation."
"Results-driven Software Engineer with 5+ years of experience in the Technology sector. Specialised in software development and algorithms, with a track record of delivering measurable outcomes. ATS score consistently above 70% against role-relevant job descriptions."
Includes: role title, years, industry, 2 core keywords, a quantifiable outcome signal.
