Job Description

Engineering Security Researcher Contract €50k – €100k Remote / In-person San Francisco / Berlin / Remote We tell companies their secrets never touch the model. That every action is permissioned. That the sandbox actually holds. Your job is to prove us wrong — and then help us fix it. You'll attack ocr from every angle: prompt injection, sandbox escapes, permission bypasses, secret exfiltration. If an agent can do something it shouldn't, you find it first. We're building a team of geniuses. Not a team of "smart people" — actual geniuses who ship. You've built things before — maybe a company, maybe projects that people actually use. You want to work unreasonably hard on something that matters. If you fall short of that standard, you're wrong here. What you will do Continuously probe the agent runtime for vulnerabilities — sandbox isolation, permission enforcement, secret handling, integration scoping. Develop attack scenarios that model real‑world threats: malicious prompts, tool misuse, multi‑step exploits across agent sessions. Write clear, reproducible findings and work with engineering to close gaps. Help define security architecture decisions as the platform evolves — threat models, trust boundaries, defense‑in‑depth strategy. What we are looking for Deep experience in application security, penetration testing, or red teaming. You've found real bugs in real systems. You understand LLM‑specific attack surfaces — prompt injection, jailbreaks, indirect prompt injection, tool‑use exploits. This is not theoretical for you. Strong systems background. You're comfortable reading Go, understanding container isolation, and reasoning about permission models at the code level. You can communicate findings clearly to engineers who will fix them. No 40‑page reports that sit in a drawer. Self‑directed. Contract means you set your own pace, but you deliver consistently and proactively. Read our values before applying. We default to open — including about what we get wrong. Why OpenCompany Competitive contract rate. You're securing the runtime that companies trust to run AI agents in production. The stakes are real. Direct access to the entire codebase and engineering team. No bureaucracy between finding a bug and shipping a fix. Early‑stage company where your work directly shapes the security posture of the product. Flexible engagement — remote‑first, set your own hours, deliver results. #J-18808-Ljbffr OpenCompany
