Software Engineer, Security
Sierra, San Francisco, CA
The role
Security Engineering builds the foundations that let Sierra deliver powerful AI agents while protecting customer data and trust. We partner across product and platform to make security, privacy, and safety core product capabilities and secure defaults.
What you will do
Our work spans several security domains. You’ll go deep where your strengths and interests are strongest, with opportunities to explore new areas alongside the team.
Build the Foundations of Trust. Design and ship systems that make Sierra’s platform secure by default — spanning agent safety/security, privacy, identity, authentication, authorization, and data security. You’ll work across all layers of production (agents, infrastructure, backend, frontend) to embed security-conscious design into the core of our product.
Own Cross-Cutting Systems. Partner with product and platform teams to implement and evolve Sierra’s trust primitives: identity management, access control, auditability, and data lifecycle management. You’ll make pragmatic design trade-offs between usability, performance, and security.
