ATS systems at tech companies don't score resumes the same way non-tech recruiters do. They're looking for specific tools, languages, frameworks, and methodologies — and they care about exact terminology, not paraphrases. 'Experience with databases' will not match a query for 'PostgreSQL'.
Tech roles are among the most ATS-filtered positions in the market. Companies like Google, Amazon, and Meta process millions of applications annually. Without the right keyword signals, your resume is invisible — regardless of your actual skill level.
How ATS keyword matching works in tech hiring
Technical ATS systems (Workday, Greenhouse, Lever, iCIMS) parse your resume and compare it against a scored list of required and preferred skills from the job description. The recruiter sees a match percentage. Higher match = higher in the stack.

The keyword placement rule
Keywords should appear in at least two places to signal genuine experience: once in your Skills section (as a named tool or technology) and once in your experience bullets (in context, showing how you used it and what outcome it produced). Keyword stuffing in a footer or hidden text no longer works — modern ATS systems score contextual relevance.
HireSprint extracts the exact keywords from any tech job description and shows you which ones are missing from your resume — sorted by importance. One click tailors your skills section and rewrites relevant bullets to match.
