AI Engineer

Role Overview Pi is building an agentic product security platform for teams that need to secure software at the speed they build it. We connect security knowledge scattered across code, tickets, documents, incidents, reviews, and people. This institutional security memory helps teams triage faster, remediate in context, prevent recurring vulnerability classes, and bring security guardrails into everyday engineering work.

We’re looking for an AI Engineer to build reliable agents, improve our AI infrastructure, and turn advances in LLMs into useful security features.

This role requires working in person at our San Francisco office five days per week.
