Location: Bay Area (Hybrid/Onsite)
We’re looking for a Senior SDET who goes beyond testing to engineer solutions that surface and resolve issues before they reach production. If you think like an engineer first, write production-quality code, and love digging into distributed systems, security, and low-level system behavior—this is your role.
What You’ll Do
Build, not script: Design and develop scalable, maintainable automated test systems for APIs, services, and UI
Own quality end-to-end: From test strategy → frameworks → execution → release confidence
Break things intelligently: Identify edge cases, failure modes, and security gaps across distributed systems
Go beyond black-box testing: Validate system behavior at multiple layers—API, infra, and (ideally) OS-level
Engineer test frameworks that validate:
- Functionality
- Performance
- Reliability
- Security (not optional here)
Partner deeply with engineers to influence design, not just validate it
Drive CI/CD quality gates and release readiness across the platform
Debug real systems: Work cross-functionally to root-cause issues (not just report them)
Continuously evolve testing practices in a fast-moving security + AI environment
What You Bring
6+ years as an SDET (or SWE with strong testing ownership)
You write real code (not just test scripts) in languages like Python, Go, Java, or C++
Strong understanding of distributed systems, APIs, and backend services
Experience building or extending test frameworks from scratch
Hands-on experience with:
- CI/CD pipelines
- Cloud environments (AWS, GCP, or Azure)
- Containers (Docker/Kubernetes)
Solid grasp of security fundamentals (auth, encryption, attack surfaces, etc.)
Ability to debug complex systems and identify root causes
Bonus Points
- Experience with Rust
- Exposure to Confidential Computing (SGX, SEV, Nitro, etc.)
- Systems-level knowledge (Linux internals, kernel, networking)
- Background in security or adversarial testing
What Makes You a Fit
You think like a builder, not a QA gatekeeper
You’re skeptical in the best way—you assume things will break
You care about performance, scale, and security, not just correctness
You’re comfortable going deep technically and pushing engineers (in a good way)
You take pride in preventing issues—not just finding them
We offer a collaborative work environment, amazing equity, great benefits, competitive salary.
Unlimited PTO (it’s between you and your work!)
40 hours of Volunteer Time Off/year
Internet stipend
Friendly culture that brings the best out of everybody
