Entering this domain positions you at the heart of IBM, where growth and innovation thrive.Your Role And ResponsibilitiesWe 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-forgeAs 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.Your Role And ResponsibilitiesUI Development Build CRUD interfaces: tools, servers, A2A agents, gateways, prompts, resources with RBAC Create real-time features: log viewer with filtering, search, export capabilities Implement WebSocket streaming for live updates and event monitoring Design metrics dashboards: integration with Prometheus, charts, visualizations Build responsive layouts: mobile-first design with Tailwind CSS, eventually transitioning to a new stack Develop dark mode toggle and theme managementFederation & Virtual Server UI Create federation UI: peer gateway status, health checks, tool aggregation visualization Build virtual server composition interface: drag-and-drop tool selection, visual builder Implement A2A agent configuration UI: agent registration, parameter configuration Design connection string exports: code snippets for client configuration Create visual representations of complex system stateHTMX & Server-Driven Architecture Implement HTMX patterns: server-driven partial updates, out-of-band swaps Design hypermedia-driven workflows: progressive enhancement, graceful degradation Integrate with FastAPI backend: Jinja2 templates, endpoint coordination Optimize for low JavaScript footprint: leverage HTMX for interactivity Create reusable HTMX components and patternsAlpine.js & Interactivity Use Alpine.js for lightweight client-side reactivity: modals, dropdowns, accordions Implement form validation and client-side state management Create interactive components: data tables, filters, search interfaces Handle client-side routing and navigation enhancements
