This is a build-and-define role: MCP tooling for GraphQL is still young, and this engineer will help shape how agents interact with federated graphs ensuring MCP spec compatibility, designing tools, improving introspection and execution reliability, and building the Skills that make agent workflows useful in production. For someone with a strong interest in Federation, there's room to work across the boundary, contributing to composition and query planning where MCP/Skills work intersects with core Federation. The ideal candidate is a strong systems engineer with product instincts — someone who's energized by defining a new interface layer, but who also brings the rigor to keep it running: operational maintenance,...
