About the role
We find and fix every vulnerability in our customers' applications. When a new AI model is released, we run it against their applications before attackers do, and close what it finds.
The Role
Wakefield's agents run in sandboxes for hours at a time, sign in to customer applications as many users at once, drive real browsers, and record everything they do. All of their traffic goes through one controlled path. You'll own the layer they run on: sandboxes and browsers, the egress proxy, the system that schedules and runs scans, and the deployment that keeps each customer's data apart.
What You'll Work on
- Sandboxes that start fast, hold state through long scans, and can be replayed.
- Browser infrastructure for agents that sign in as many roles at once and record every step.
- The egress proxy every agent request goes through: scope checks, rate limits for each organization, and a full record.
- Running scans on demand, on every pull request, and against every new model release.
- Tenant isolation, and one deployment model for our cloud and for customers who need their own.
- Internal AI tooling that automates our infrastructure, deployment monitoring and maintenance.
Requirements
- 2+ years of engineering experience, or equivalent depth from research, open source or your own projects
- Time at a fast-growing startup
- You've designed and built systems from scratch
- You've scaled and operated production infrastructure under real load
- Strong systems fundamentals: distributed systems, Linux, Kubernetes, networking, concurrency
- You use coding agents every day and still understand every line you ship
- You build and tinker for fun because you genuinely care about how the technology works
Nice to Have
- You've built a sandboxing, browser automation or durable execution product
How We Hire
- Meet the co-founders.
- A one-week paid trial with us in the office.
- Offer.
Logistics
- Location: San Francisco, in person. Most of the team is in the office every day.
- Compensation: Competitive salary and meaningful equity.
- Visa: We sponsor visas and support you through the immigration process.
About Wakefield
Wakefield is an applied research lab working on AI-native security services. We build security agents and publish how they work. Our methods, benchmark and raw data are public so anyone can check them.
- Source code optional: blackbox agents sign in as every role and test the running app. Whitebox agents read the code on every pull request.
- If Wakefield can't prove it, the customer never sees it: agents replay each finding in a real browser and record it. Then Wakefield writes the fix, ready to open as a pull request, and retests it. We have SLAs for zero false positives.
- One service that replaces DAST, SAST, SCA, SBOM, and the tests companies run in-house or buy in.
