Application Security Engineer Resume Examples & Free Template (PDF, Word)

1. 1

   Title, years and scope

   Your years and the exact title from the job ad, whether that’s Application Security Engineer, Product Security Engineer or AppSec Engineer. Then say what you protect, like a SaaS app, payments or mobile, and the 2 or 3 areas you’d lead with.

2. 2

   Your stack

   Your tools, sorted into the groups AppSec postings use: review languages, SAST, DAST, SCA and the bug bounty platform. Recruiters search by product name, so match the ad’s product names letter for letter.

3. 3

   Domain expertise

   3 or 4 areas where you go deep (threat modeling, API authorization, custom scanner rules), the method you use, like OWASP SAMM or risk-tiered reviews, and the result. To a hiring manager, that’s the part of the program you could pick up on day one.

4. 4

   Collaboration

   Who you work with (product engineers, platform, privacy, compliance) and where: design reviews, launch reviews, the bounty triage call. Security advice only gets used when developers trust the person giving it, and recruiters know that.

5. 5

   Leadership

   The things other teams keep using after you’ve moved on: secure-by-default libraries, a champions program, a Semgrep rule library, engineers you coached. No direct reports needed. It shows a manager you make the whole engineering org safer, not just your own queue.

1. 1

   Threat Modeling & Secure Design Review

   You catch design flaws before anyone’s written the code. A broken trust boundary found in a design review costs an afternoon, but in production it’ll cost a release, so managers look for designs you’ve changed. Walk them through how you used data-flow diagrams and STRIDE to get risky designs changed before the first commit.

   Techniques

   data-flow diagrams, trust boundary analysis, STRIDE sessions, design sign-off

   Tools

   OWASP Threat Dragon, Microsoft Threat Modeling Tool, IriusRisk, Jira

   Metrics

   designs reviewed, threats fixed in design, review turnaround

2. 2

   Secure Code Review

   You read the code that scanners can’t judge, like auth checks and sharing logic. Business-logic flaws are what end up in breach reports, and you won’t find them with a tool. Describe how you used manual review and a risk-based list of hot spots to stop those bugs in pull requests.

   Techniques

   risk-based review, authorization checks, business-logic review, secure-coding checklists

   Tools

   GitHub pull requests, Semgrep, CodeQL, Sourcegraph

   Metrics

   bugs caught in review, vulnerabilities in production, repos covered

3. 3

   Security Testing in CI/CD

   You tune the scanners so developers actually act on what they find. Developers stop reading a noisy pipeline after a few weeks, and that’s why your false-positive rate matters to a hiring manager. Explain how you used custom Semgrep rules and merge gates to block real bugs without slowing the team down.

   Techniques

   custom rule writing, false-positive tuning, merge gates, secret scanning

   Tools

   Semgrep, CodeQL, GitHub Actions, Gitleaks

   Metrics

   false-positive rate, findings blocked at merge, scan coverage

4. 4

   Application Penetration Testing

   You break the app yourself before attackers or pentest vendors do. Outside pentests aren’t cheap and usually happen once a year, so a manager wants someone who’ll test every big launch. Show them how you used Burp Suite and the OWASP ASVS checklist to find serious issues before release.

   Techniques

   pre-launch testing, ASVS-based test plans, mobile API testing, retests

   Tools

   Burp Suite Professional, OWASP ZAP, Postman, Frida

   Metrics

   launches tested, high and critical findings, fixes confirmed on retest

5. 5

   Vulnerability Triage & Bug Bounty

   You turn a pile of findings into fixes with deadlines. Bug bounty reports, scanner results and pentest findings all end up with you, and if you’re slow, a researcher may go public. Tell them how you used CVSS scoring and fix deadlines to cut the time critical bugs stay open.

   Techniques

   CVSS scoring, severity deadlines, bounty triage, fix retesting

   Tools

   HackerOne, Bugcrowd, Jira, DefectDojo

   Metrics

   median time to fix, valid reports, findings past deadline

6. 6

   API & Authentication Security

   You lock down the logins and APIs the whole product depends on. Broken access control is A01 in the OWASP Top 10, and it only takes one missing object-level check to expose every customer’s data. Point out how you used OAuth 2.0 scopes and shared authorization code to close whole classes of API bugs.

   Techniques

   OAuth 2.0 scope design, object-level authorization, rate limiting, session hardening

   Tools

   OAuth 2.0, OpenID Connect, JWT, HashiCorp Vault

   Metrics

   endpoints hardened, BOLA bugs closed, auth findings

7. 7

   Software Supply Chain Security

   You keep third-party code and the build pipeline from becoming the way in. Most of a modern app isn’t written in-house, it’s open-source packages, and attackers now poison those packages on purpose. Mention how you used SCA, SBOMs and signed builds to patch vulnerable dependencies in hours, not weeks.

   Techniques

   dependency upgrades, SBOM generation, artifact signing, secret rotation

   Tools

   Snyk, Dependabot, Syft, Sigstore

   Metrics

   old critical dependency vulnerabilities, time to patch, SBOM coverage

8. 8

   Security Champions & Developer Enablement

   You make the secure way the easy way for developers. A small AppSec team can’t review the work of hundreds of engineers, so managers want people who’ll scale through others. Let them know how you used a champions program and safe-by-default libraries to cut repeat bugs across teams.

   Techniques

   security champions, secure-coding labs, paved roads, office hours

   Tools

   OWASP SAMM, Secure Code Warrior, Confluence, Slack

   Metrics

   active champions, engineers trained, repeat bug classes

Moving over from pentesting or QA? Your findings count, as long as each one ends with a fix that shipped. Never run a champions program? Keep the area anyway and write about the developers you’ve taught.

1. Level 1Task

   What did I work on? Start with one real piece of work and a strong verb. On its own, it could be anyone’s bullet.

   Pentested a new team sharing feature before launch.

2. Level 2+ Techniques

   How did I do it? Add your techniques. This is where a hiring manager sees whether you tested by hand or just ran a scan.

   Pentested a new team sharing feature before launch, using manual authorization testing and parameter tampering.

3. Level 3+ Tools

   What tools did I use? Write the product names. Recruiters search the ATS for “Burp Suite”, not “testing tools”.

   Pentested a new team sharing feature before launch with Burp Suite Professional and Postman, using manual authorization testing and parameter tampering.

4. Level 4+ Method

   What method did I follow? Mention the standard you tested against. OWASP ASVS tells them your testing had a plan behind it.

   Pentested a new team sharing feature before launch with Burp Suite Professional and Postman, using manual authorization testing and parameter tampering against an OWASP ASVS Level 2 test plan.

5. Level 5+ Metric

   What was the result? Finish on one number an engineering director would care about, like the serious bugs you stopped before launch.

   Pentested a new team sharing feature before launch with Burp Suite Professional and Postman, using manual authorization testing and parameter tampering against an OWASP ASVS Level 2 test plan, and found 6 high-severity access bugs that were fixed before release.

   1. 01 Task What you worked on
   2. 02 Techniques How you did it
   3. 03 Tools The stack you used
   4. 04 Method The method you followed
   5. 05 Metric The result, one number

Most AppSec engineers have more numbers than they’d guess. HackerOne shows when each report came in and closed, your scanner dashboard tracks findings over time, and Jira has every fix date. Pull a year of data before you write a word.
