Apply

What you will work on

  • Build adversarial harnesses against the policy gate, identity boundaries, and audit trail.
  • Land CI checks that block releases when known scenarios lose required evidence or decisions.
  • Turn field failures into regression tests for approvals, scope, and containment.
  • Keep the eval corpus current as tools, MCP servers, and sub-agents change.

What we look for

  • Built (not only used) adversarial or red-team infrastructure that caught a real bug.
  • Production code on a CI path.
  • Comfortable in agent frameworks (MCP or similar) and security tooling.
  • Shipped at least one release-blocking check someone tried to disable.
