About the Security Engineer role
Security Engineers build security directly into the product — secure authentication and authorization systems, encryption, dependency management, and the code review process that catches vulnerabilities before they ship. Distinct from IT-focused security roles, this position sits inside the engineering org and treats security as a feature of the product itself.
Skills you'll need

Typical credentials
- •3+ years of software engineering experience with a security specialization, or dedicated appsec experience
- •Direct experience designing or reviewing authentication and authorization systems
- •Familiarity with a bug bounty or responsible disclosure process is a plus
- •A security certification (OSCP, GWAPT) helps but hands-on shipped security work matters more
Resume tips for Security Engineer applications
- •Highlight security features you designed, not just vulnerabilities you found
- •Quantify vulnerabilities caught in review, or reduction in critical findings over time
- •Name the specific auth/authorization systems you've built or hardened
- •Mention any bug bounty or responsible disclosure program experience
- •Keep it to one page, technical and specific

Sample cover letter for Security Engineer
Same idea — a structure to learn from, not to send as-is.
Dear Hiring Manager,
I'm applying for the Security Engineer role because building security into a fintech product from the inside is exactly the work I've focused my career on. At Paylight, I redesigned our authentication system to support SSO and MFA, cutting account-takeover incidents by 90%, and built an automated dependency-scanning pipeline that catches vulnerable packages before they ever merge.
I also reviewed over 200 pull requests for security issues last year, catching 15 critical vulnerabilities before they reached production — the kind of quiet, unglamorous work that actually prevents incidents.
I'd welcome the chance to bring that same approach to your product.
Sincerely,
Zara Hussain
