We’re building an Agentic AI Security Platform that helps teams secure autonomous AI workflows. We’re looking for a senior engineer to help design and ship core systems across policy enforcement, runtime monitoring, incident workflows, and auditability.

You’ll work across backend and product surfaces: Rust + gRPC services, GraphQL APIs, and TypeScript/React interfaces for security operations. You should be comfortable owning features end-to-end, making pragmatic architecture decisions, and collaborating closely with product/security teams in a small, fast-moving environment.

Strong fit if you have experience with distributed systems, secure-by-default engineering, and production observability. Security product background is a plus, but not required if you’re excited to learn quickly and build in this space.

If this sounds interesting, email us at [[email protected]] with Resume/CV plus links to your GitHub/LinkedIn and a short note on systems you’ve built.
