Concord AI builds local-first tooling so AI coding agents can coordinate through shared presence, claims, messaging, and task memory instead of colliding on the same files. Open source: get-concord-ai/concord-mcp (@concord-ai/concord-mcp). What you'll do: full-stack features; small PRs across UI, API, and data; TypeScript/JavaScript, React, Node.js; docs and examples; async remote teamwork.

HTML, CSS, JavaScript or TypeScript; React and Node.js preferred; end-to-end project experience; clear English; reliable internet.
