Full-Stack Software Engineer - Core Platform

About UsWe build the operating system for agentic AI in environments where failure isn't an option. In our first ten months we won four U.S. Government prime contracts in open competition, every one deployed into classified infrastructure, beating established defense primes head to head. Our team comes from the intelligence community, special operations, and frontier AI research. We've lived this problem from the inside.About The RoleOur core platform turns days of manual synthesis into minutes of insight. You'll own features end to end, Python backend to React frontend, putting real AI tooling directly in analysts' hands. This isn't greenfield work for its own sake; what you build runs in production environments where the stakes are real.What You'll DoBuild and own FastAPI endpoints backed by PostgreSQL for agent configuration, workflow orchestration, and evaluation pipelinesImplement React/TypeScript features: conversation interfaces, workflow visualization, knowledge-graph explorationDesign durable orchestration for long-running agent execution — delegation, monitoring, timeout propagationWrite contract-driven, test-first code across the full stack, from database migration to UI stateOwn performance at every layer, API latency, query efficiency, render performance, streaming. Treat slowness as a bugContribute to Python and TypeScript client SDKs so programmatic consumers get ergonomic, well-typed accessDebug across service boundaries using distributed tracingYou're a Fit If YouShip production Python (async, relational modeling, layered services) and production React/TypeScriptReason clearly about data flow from schema to UI stateWork test-first and write code other people can maintainNice to HaveExperience with agentic AI systems or LLM APIsDistributed task orchestrationGraph databases or vector searchOAuth2/OIDC identity managementBackground in intelligence analysis or analytical workflowsU.S. citizenship is required.
