MCP Platform Engineer

What you will do

• Build and operate MCP (Model Context Protocol) servers that expose tools and data to agents safely.
• Own the agent gateway — runtime, scheduling, auth, and the boundaries between agents and the systems they touch.
• Implement agent-to-agent collaboration: how agents discover, delegate to, and hand off work.
• Integrate LLMs (Claude / Anthropic API and others) — tool use, structured output, context, cost and latency control.
• Run it in production — deploy to EKS/AKS via ArgoCD/Helm, target IL2+ environments, ship through our weekly release train.

What we are looking for

• Must be a US Citizen and able to support US Government Contracts.
• Strong Python — you design and ship production services, not just scripts.
• Hands-on LLM application development (agents, tool/function calling, RAG, or MCP). You have built something real.
• Comfortable with Kubernetes and GitOps deployment (Helm, ArgoCD, or equivalent).
• Solid grasp of API design, auth, and securing service-to-service communication.
• Nice to have: direct MCP experience, FastAPI, multi-agent frameworks, IL2+/FedRAMP environments.
