How to Write a Application Security Engineer Resume
Professional Summary
Highlight the scale of your AppSec program (number of applications, services, developers). Quantify vulnerability reduction and show both proactive (threat modeling, training) and reactive (code review, bug bounty) experience.
Work Experience
Emphasize shift-left achievements: automated security in pipelines, developer training impact, and vulnerability reduction over time. Include programming languages you review code in.
Skills Section
List SAST/DAST/SCA tools by name, programming languages for code review, and security frameworks. AppSec engineers need both security and software development skills.

Not listing programming languages you can review
AppSec engineers must read code. List every language you review (Go, Python, Java, TypeScript, etc.) with proficiency levels
Focusing only on tools and not methodology
Include threat modeling approaches (STRIDE, DREAD), secure SDLC frameworks, and training programs you developed or delivered
Omitting developer enablement work
Highlight security champions programs, training delivery, and documentation. AppSec is as much about enabling developers as finding bugs.
Not quantifying vulnerability reduction over time
Show trends: "Reduced critical vulnerabilities by 78% over 2 years" demonstrates sustained impact
Leaving out bug bounty program management
If you managed a bug bounty program, include metrics like reports triaged, average response time, and payouts managed
Application Security Engineer Resume FAQs
What is the difference between AppSec engineer and security engineer?
AppSec engineers focus specifically on software security: code reviews, SAST/DAST, threat modeling, and developer training. Security engineers have a broader scope including infrastructure, network, and endpoint security.
Do I need to know how to code for AppSec roles?
Yes. Strong programming skills are essential. You need to read and review code, write custom security tooling, and integrate security into CI/CD pipelines.
What certifications are best for AppSec engineers?
CSSLP for secure software lifecycle, GWEB for web application testing, and OSWE for advanced web exploitation. OSCP also adds value for understanding offensive techniques.
How do I transition from software engineering to AppSec?
Start by becoming a security champion on your team, learn OWASP Top 10, practice on WebGoat and Juice Shop, and pursue CSSLP certification. Your development experience is a major advantage.
Should I include open-source security contributions?
Absolutely. Contributions to security tools, custom rules (Semgrep, ESLint security), or vulnerability disclosures demonstrate initiative and expertise.
