Security Engineer
Nooks, San Francisco
The role
Nooks is the Agent Workspace for Sales, where reps and AI agents execute and decide next moves together across 1M+ interactions per day. As our second security engineer, you'll help secure a fast-growing, AI-native platform and the customer data that flows through it — across a rapidly expanding set of product surfaces. This is a foundational, high-ownership role: you'll shape our security program from the ground up, including the novel challenge of securing AI agents and how they're used within organizations.
What you will do
- Own security reviews and threat modeling for new and existing product surfaces.
- Build and improve core security processes (secure SDLC, detection & response).
- Harden our cloud and application infrastructure and drive remediation of high-priority risks.
- Help define how we secure AI agents and govern their use — guardrails, data exposure, prompt-injection and abuse risks.
- Support enterprise customer trust: compliance (SOC 2), and customer-facing security needs.
- Partner closely with product and infra engineering to embed security into how we ship.
