← All resourcesWhat recruiters look for first
A security engineer resume gets ranked in seconds. These are the five signals a recruiter (and an LLM-ranked ATS) checks before deciding whether to keep reading.
- Sub-discipline declared: appsec, cloud security, IR / blue team, red team, etc.
- Frameworks named: SOC 2, ISO 27001, NIST, OWASP, MITRE ATT&CK
- At least one shipped control or detection (not just "audited")
- Tooling named: Snyk, Semgrep, Wiz, Crowdstrike, Tines, etc.
- Cert(s) listed if you have them: CISSP, OSCP, CCSP, etc.
Bullet patterns that work
Every strong security engineer bullet follows the same shape: action verb → what you built → who it was for → a number that proves the impact. Use these patterns as a scaffold, not a script.
Pattern
Shipped [control] reducing [risk] in [system]Example
Shipped a Semgrep ruleset across 14 backend services reducing high-severity SQL injection findings by 92% over 4 months
Pattern
Led [audit / certification] for [scope], passing on first attemptExample
Led the SOC 2 Type II audit for the production AWS estate, passing on first attempt with zero exceptions
Pattern
Built detection for [threat], catching [N events] in productionExample
Built a Tines + Snowflake detection pipeline for credential stuffing, catching 11 active campaigns in the first month
Skills section — what to keep
Recruiters skim skills sections for the keywords the JD mentioned by name. Lead with the hard skills, group your tools, and keep soft skills short.
Hard skills
- Threat modeling
- Vulnerability management
- IAM design
- Incident response
- Detection engineering
- Code review for security
Tools
- Semgrep
- Snyk
- Wiz
- Crowdstrike
- Splunk
- Tines
- AWS IAM
- Burp Suite
Soft skills
- Cross-team enablement
- Calm under incident
Pitfalls that get security engineers filtered
- Listing every framework in compliance instead of which ones you've owned
- Calling yourself security without naming a sub-discipline
- Padding with vague "hardened" verbs — be specific about controls
- Skipping incident response work if you have it (it's a top signal)
Frequently asked
Are certs required for security engineer roles?
Not required, but they shift the resume past automated filters. CISSP is the broadest signal; OSCP for offensive; CCSP for cloud.
How do I move from IT security to product security?
Lead with code review, threat modeling, and any AppSec automation you've shipped. Cut the helpdesk-adjacent bullets unless they prove a security skill.
Should I name CVEs I've discovered?
Yes — CVE numbers are a strong external credibility signal. List them with the affected product and severity.
