Strong verbs open every bullet
Triaged, Authored, Investigated, Built, Shadowed. Each bullet leads with action that proves you drove the work, not waited for findings to arrive in your queue.
Numbers turn AppSec work into evidence
1,200+ SAST findings, true-positive rate from 0.42 to 0.78, 22 custom Semgrep rules, 156 vulnerable packages, 230+ misconfigurations. Without metrics, code review reads like a chore log.
Context turns scan output into security outcomes
Not 'ran scans' but 'with severity-based JIRA routing'. Not 'reviewed code' but 'across 48 production repos'. Context proves you understood the systems you were defending.
Collaboration signals even at entry level
Adopted by 3 product teams, shadowed senior product-security engineer, threat models for 4 new microservices. Junior AppSec is embedded work, your CV must show people you worked with.
Tools shown in achievements, not listed in a stack
'Built nightly Trivy and Snyk container scans' beats 'Trivy, Snyk'. Tools live inside what you shipped, proving you used them in anger, not skimmed a tutorial.

Career Progression
Application Security careers progress from triage and rule-writing into program ownership and org-wide strategy. The fastest growth path is to specialize in one of: threat modeling, SAST/CodeQL detection engineering, supply-chain provenance, or ASPM strategy. Compensation accelerates sharply at senior+ because vendor decisions and program ownership compound across product orgs. Lead AppSec at top-tier companies enters CISO-track territory, with some lateral moves into Head of Product Security or VP Engineering Security.
Ship one open-source Semgrep ruleset with measurable adoption, own end-to-end vulnerability disclosure intake on HackerOne, complete one full embedded engagement with a product team longer than 3 months, and earn OSCP or GWAPT.
- Threat modeling (STRIDE)
- Custom Semgrep rule authoring
- Burp Suite Pro and Caido fluency
- Container and IaC security (Trivy, Checkov)
- Vulnerability disclosure operations
Drive one vendor swap with a documented dollar reclaim, own a threat-modeling rotation across 5+ services, mentor 1-2 SDEs into AppSec rotation, ship pre-prod gating that closed pre-release a measurable share of high-severity findings, and earn OSWE or AWS Security Specialty.
- ASPM tooling (Apiiro, OX Security, Endor Labs)
- CodeQL custom queries
- Supply-chain provenance (Sigstore, Cosign)
- Detection engineering at scale
- Cross-team program ownership
Own AppSec across 5+ product orgs with measurable coverage delta, drive a multi-million-dollar vendor consolidation, scale a security-champions program past 50% of teams, deliver quarterly readouts to CTO or audit committee, and ship supply-chain provenance org-wide on SLSA Level 3.
- AppSec program design and budgeting
- Vendor negotiation and procurement
- Board and audit-committee communication
- Bug-bounty program economics
- Founding and hiring an AppSec org
AppSec engineers can pivot into red team or offensive security research, security platform engineering (building internal AppSec tooling), founder/early-engineer roles at AppSec startups (Semgrep, Endor Labs, OX Security), security product management, or DevSecOps platform leadership. The CISO track typically routes through lead AppSec into Head of Product Security and onward.
Application Security Engineer CV: How to Get Hired Inside Product Engineering, Not Next to It
Application Security is the role hiring managers say they want to fill but rarely do well. AppSec is not IT security. It is not a SOC analyst rotation. It is not GRC writing policies. It is an engineering role embedded with product teams, owning threat models, SAST and SCA pipelines, supply-chain provenance, and the secure-SDLC. Recruiters at Stripe, Cloudflare, GitHub, Datadog, Atlassian, and Coinbase scan your CV for one signal: do you read code and ship guardrails, or do you forward findings and call it a program.
The brutal truth is that most AppSec resumes get filtered for the same reason. They list 'reviewed code for security' instead of 'shipped a Semgrep gate with autofix in 47 repos'. They name CISSP at the top of page one and mention Burp Suite once. They claim 'reduced vulnerabilities' without an SLA-violation number. The hiring loop wants to see signal-to-noise, not certification stacks.
This guide breaks down what works at each AppSec level: junior triaging SAST findings and writing Semgrep rules, mid-level embedding with one product org and running threat models, senior owning the program across 5+ orgs and making ASPM vendor decisions, lead setting org-wide strategy and presenting risk to the audit committee. Every example is built from real tools (Semgrep, CodeQL, Snyk, Veracode, Checkmarx, Trivy, OSV-Scanner, Sigstore, Cosign, Apiiro, OX Security, Endor Labs, HackerOne, Bugcrowd) and real metrics (true-positive rate, MTTR, threat-model coverage, payout-per-critical) that hiring managers actually pattern-match on.
