What an ATS looks for in a software engineer resume
Most software engineer applications are read by an applicant tracking system (ATS)before a person ever sees them. The software ranks your resume against the job description's skills, tools, and titles — and filters out the ones that don't line up. The fix isn't a fancier template; it's making sure the terms a software engineerrole is scored on are on the page, where they're genuinely true of you.

How long should a software engineer resume be?
One page if you have under ~10 years of experience, two at most for senior or staff roles. Recruiters skim — keep your strongest, most relevant work on page one.
Should I list every programming language I know?
No. List the languages and tools you'd be comfortable defending in an interview, and prioritize the ones named in the job description — those are what the ATS matches against.
