Lead Security Researcher

Location: San Francisco, CA or Israel · Type: Full-time, onsite

About Us

Pi Security is a product security company in San Francisco, founded by the teams who led Microsoft's vulnerability mitigation efforts and Tesla's offensive research.

We built a platform for the agentic SDLC. It changes how companies handle security vulnerabilities, not by finding more of them, but by understanding them deeply enough to fix them at the root and keep entire classes from coming back. The hard problems behind that (what to detect, how to prove a finding is real, how to remediate the way a senior engineer would) are research problems. That is where you come in.

The Role

You will lead security research at Pi. This is not a bug hunting role. Your job is to invent the approaches that become product capabilities: new ways to detect, triage, and remediate vulnerabilities using LLMs and program analysis, proven on real data before a customer ever sees them.

You own the path from idea to shipped capability. You form the hypothesis, build the proof of concept, measure whether it actually works, and partner with engineering until it is in the product. You also own the quality bar: the benchmarks and evaluations that decide whether what we ship is good enough to put
