We are seeking experienced Web Developers to join the ContextForge MCP Gateway team to build and enhance the Admin UI and eventually transition to a new UI stack.

ContextForge is an open-source production-grade gateway, proxy, and registry for Model Context Protocol (MCP) servers and A2A Agents. It federates MCP and REST services, providing unified discovery, auth, rate-limiting, observability, virtual servers, multi-transport protocols, plugins and an Admin UI: https://github.com/IBM/mcp-context-forge

As a Senior Web Developer, you will build the Admin UI using HTMX, Alpine.js, and TypeScript - creating real-time dashboards for MCP gateway operations. You will work on CRUD interfaces, real-time features, federation visualization, and virtual server composition tools. This role is ideal for developers experienced with server-driven UI patterns (HTMX) or willing to learn an alternative to heavy client-side frameworks like React.
