Generic templates don't work for Security Engineers. You need to prove you can handle proving you reduce real risk and ship secure systems, not just file vulnerability tickets nobody closes.
Don't just list "Hard Worker." The ATS is scanning for these exact technical skills:
A common mistake for Security Engineers is listing duties instead of achievements.
Try this:
Show risk reduced: "Built automated SAST/DAST pipeline, cutting critical vulnerabilities in production by 78% and mean-time-to-remediate from 45 to 6 days" beats "Handled security tasks".
Applicant tracking systems scan a Security Engineer resume for specific keywords before a human ever sees it. Prioritize: Application Security, Threat Modeling, SIEM, Penetration Testing, IAM, Vulnerability Management. List them in a dedicated Skills section and, more importantly, prove each one inside your experience bullets with a measurable result.
Security Engineer roles in the US typically pay $120k - $200k. Quantifying your impact on your resume — revenue influenced, users served, cost saved, time reduced — is the single fastest way to justify offers at the top of that band.
Keep it to one page if you have under ~10 years of experience, and two pages maximum for senior Security Engineers. ATS parsers read either length, but recruiters spend roughly seven seconds on the first scan — lead with impact and cut anything older than 10–15 years.
Use a single-column layout with standard section headings and no tables, text boxes, columns, or images. Mirror the exact language of the job description (Application Security, Threat Modeling, SIEM…), export as a text-based PDF, and test it against a real parser. Resumefy scores your resume against any job description and shows what is missing — free.
Listing responsibilities instead of achievements. For example: Show risk reduced: "Built automated SAST/DAST pipeline, cutting critical vulnerabilities in production by 78% and mean-time-to-remediate from 45 to 6 days" beats "Handled security tasks".
No — the highest-converting approach is one master profile that you tailor to each posting so your keywords match. Resumefy keeps a single Master Profile and auto-generates a tailored, ATS-optimized Security Engineer resume for any job in about 30 seconds.
