Senior Security Test Engineer
Mission
Own security testing for a product area
Tour of Duty
Lead a project that improves security posture
About This Job Family
People in this job family ensure products work as intended before customers find out they don't. They design test strategies, build automation frameworks, and catch bugs that would otherwise ship. Quality isn't just testing—it's building confidence that the product does what it should.
What You'll Do
Security Testing Engineers find vulnerabilities before attackers do—conducting penetration tests, security assessments, and code reviews. They think like attackers to protect systems. Success means vulnerabilities found and fixed before they're exploited.
- • Own security testing for product areas end-to-end
- • Design security testing strategies for medium-complexity systems
- • Identify complex vulnerability chains and attack paths
- • Lead security review sessions for new features
- • Mentor junior engineers on security testing practices
- • Drive security improvements that reduce risk
Every responsibility is an accomplishment waiting to happen. The question is: will you own the outcome, or just do the task?
AI as an Accelerator
AI isn't a skill we call out. It's invisible in the accomplishment but easily visible in the velocity and scale of your outcomes. Here's how people in this role are accelerating their work with AI:
- → Modeling threat scenarios
- → Reviewing security code
- → Creating baselines

Your Journey From Here
Going up? Your next Tour of Duty:
→ Staff Security Test Engineer / Manager, Quality Engineering - Security (L4) "Design security testing that teams adopt"

These are your stretch accomplishments. Start doing L4 work now. When you can prove it with accomplishments, you're ready.
Going sideways? That's valid too.
Up isn't the only direction. It's your career. You own it.
