What hiring teams look for
Software Engineers win ATS screens by front-loading the highest-frequency job-description keywords (Python, AWS, React, TypeScript, REST API / RESTful API) in the summary and skills blocks, then proving each in quantified bullets that show scope, method, and business outcome.

Section order that scores
The order matters. ATS parsers weight content closer to the top, so leading with the right sections lifts your keyword score before the parser ever reaches your work history.

ATS killers to avoid
Each of these is documented to break parsing across major ATS platforms. Avoid them and your score climbs even without rewriting a single bullet.
- ATS parsers read linearly; columns cause text from left and right columns to be interleaved, creating "word salad" that fails keyword extraction.
- Rendered as images or CSS — ATS reads zero content from them.
- Phone icon (📞), email icon, or LinkedIn logo — parsed as garbled characters or skipped entirely.
- Any font not in the system font stack becomes unreadable glyphs after PDF parsing.
- ATS parsers skip headers/footers; name and email become invisible.
- Zero keyword density, zero metrics — scores near-zero on Experience component.
- Web Development" instead of "React" and "Node.js" — ATS keyword match fails on generic terms.
- JavaScript" without "React" or "TypeScript" misses role-specific keyword requirements.
- Keywords score higher when they appear in context (bullets) — skills-only placement underweights location scoring.
- Defaults to Skills section last, which places all technical keywords in the lowest-weight position. JobVouch moves Skills to position 3 (above Experience).
Frequently asked questions
What ATS score should a software engineer resume target?
Aim for 95 or higher. The structure on this page combines a single-column layout, the section order recommended for software engineer roles, and 15-25 validated keywords placed in the summary and top bullets so the resume earns location-weighted points where ATS parsers look first.
How long should a software engineer resume be?
One page for 0-5 years of experience and two pages for 6+ years. Never truncate quantified achievements to fit a single page — let the document flow cleanly to page 2 rather than dropping metrics that prove impact.
What are the most important keywords on a software engineer resume?
The highest-frequency keywords for software engineer job descriptions are Python, AWS, React, TypeScript, REST API / RESTful API. Place the top three in your summary (1.5x ATS weight) and repeat each in the top bullet of the role where you used it.
Where should skills go on a software engineer resume?
Languages | Frameworks | Cloud/DevOps | Databases | Practices) Group skills with inline category labels rather than rendering them in tables or visual grids — ATS parsers drop or scramble table cell contents.
What's the biggest formatting mistake on software engineer resumes?
ATS parsers read linearly; columns cause text from left and right columns to be interleaved, creating "word salad" that fails keyword extraction. Single-column layouts with plain text section headers parse reliably across every major ATS, while creative templates with sidebars, icons, or skill bars routinely lose data during parsing.
Should I include a photo or objective on a software engineer resume?
No photo on US resumes — most ATS platforms either reject embedded images or strip them, and some companies discard photo resumes for compliance reasons. Replace any objective statement with a 3-4 sentence professional summary that includes your top keywords.
