ATS Resume Checker for Software Engineers (2026)

There's an irony to engineering job hunts: your resume is rejected by software before an engineer ever reads it. Over 90% of large employers run applicant tracking systems — not to auto-reject you, but to store you in a database recruiters query by keyword. A resume that doesn't contain the terms they type never comes up: you're not rejected, you're never found. Engineering postings are keyword-dense — exact languages, frameworks, and infrastructure — so "built backend services" loses to a resume that says "microservices," "REST API," and "Kubernetes" when those are what the recruiter searched.

🔒 100% private. The scan runs entirely in your browser — your resume is never uploaded, stored, or sent anywhere.

3 resume tips for software engineers

1. Mirror the posting's stack, exactly. If the posting says "Amazon Web Services (AWS)" and you only wrote "cloud infrastructure," you don't match. List the specific technologies you actually used — both the full name and the common abbreviation where they differ.
2. Keep a grouped Skills section. Languages, frameworks, infrastructure, tools — a plain-text skills block is the easiest thing for a parser to read and the first place recruiters keyword-search. No tables or columns; many parsers read them out of order.
3. Quantify engineering impact. Latency cut, throughput gained, users served, cost saved, incidents reduced. "Reduced p95 latency 40% by moving X to Y" beats a paragraph about responsibilities — for the ATS score and the human after it.
