Job details
About this role
Role overview Build security infrastructure and product capabilities for AI systems that use tools and act autonomously. This staff-level role connects distributed systems and runtime security with applied AI concerns, helping enforce policies, improve auditability, and support safe product development. The work spans user-facing application flows, backend services, and platform components, with broad ownership from initial design through iteration.
Responsibilities - Design and ship product features across frontend, backend, APIs, data models, and services. - Take new modules from scoping and architecture through implementation, launch, and refinement. - Build and evolve runtime enforcement, guardrails, audit trails, and visibility for systems using the Model Context Protocol (MCP). - Partner across infrastructure and applied AI work, including tool calling, evaluations, and anomaly pipelines where they affect security or compliance. - Translate customer feedback into product improvements, balancing speed with enterprise security needs. - Use AI-assisted development tools while maintaining correctness, and contribute to evaluation and reliability practices.
Requirements - At least 5 years building and shipping production software. - Staff, principal, founding-level, or equivalent ownership and scope. - Strong backend, infrastructure, or systems experience, including distributed or data-intensive design. - Security product experience in areas such as authorization, access control, audit logging, compliance, or runtime enforcement. - Experience building or integrating MCP or similar context and tool-bridge systems, with the ability to contribute to evaluation and reliability work. - Experience in a startup or other high-velocity environment.
Nice to have - Combined backend development and infrastructure ownership, early-stage founding experience, or work on API-based and plugin-style integrations.
Benefits and work setup - Remote across the Americas and EMEA, with quarterly team offsites.
