Senior Full-Stack Engineer, Autonomous Defense

Role overview Build the platform that runs autonomous defensive agents across customer environments. You’ll own backend systems and operator-facing interfaces, making agent workflows durable, controlled, observable, and safe to use at scale. The work spans execution, orchestration, integrations, data processing, and user interfaces; the focus is production infrastructure rather than tuning AI prompts.

Responsibilities - Develop a runtime for long-running agent workflows, including checkpoints, resumable steps, cancellation, idempotency, and timeouts. - Create a versioned tool registry with schema checks, tenant-level controls, and server-side authorization. - Build connectors to security systems such as endpoint protection, firewalls, identity, SIEM, and cloud access management. - Implement safeguards for proposed changes, including simulation, impact assessment, approvals, staged rollout, rollback, and auditable records. - Build operator interfaces in React and TypeScript, with live updates over WebSockets so users can inspect and manage ongoing runs. - Strengthen tenant isolation for agent actions, including execution boundaries, egress controls, quotas, and protection against cross-tenant data leakage.

Requirements - Strong backend engineering experience, especially with distributed systems and production platforms. - Comfort delivering front-end features as part of end-to-end product work. - Ability to build systems that remain reliable across many customer environments and long-running workflows. - Understanding of how to make automated actions controlled, observable, and auditable. - Ability to work closely with AI researchers while owning the production systems that support their work.
