We’re building an Agentic AI Security Platform that helps teams secure autonomous AI workflows. Looking for a senior engineer to design and ship core systems across policy enforcement, runtime monitoring, incident workflows, and auditability. Work across backend and product surfaces: Rust + gRPC services, GraphQL APIs, and TypeScript/React interfaces for security operations. Own features end-to-end, make pragmatic architecture decisions, and collaborate closely with product/security teams in a small, fast-moving environment. Strong fit with distributed systems, secure-by-default engineering, and production observability. Security product background is a plus but not required. Apply by emailing careers@lineation.ai with Resume/CV plus links to GitHub/LinkedIn and a short note on systems you’ve built.
