The Top ATS Resume Keywords for Tech Jobs in 2025

In today's competitive tech job market, your resume needs to pass through Applicant Tracking Systems (ATS) before it ever reaches human eyes. These AI-powered systems scan resumes for specific keywords and phrases, automatically rejecting candidates who don't match the criteria. The harsh reality? 75% of resumes never make it past ATS screening.

In this comprehensive guide, we'll show you the most important ATS resume keywords for tech jobs and how our AI-powered platform helps you optimize for success.
