Build and maintain the Jan desktop app across macOS, Windows, and Linux using Tauri. Work full stack across the app: React and Node.js on the application layer, Rust on the native side. Own packaging, builds, and distribution: installers, auto-update, release pipelines, and code signing. Give Linux first-class support: packaging and distribution across common distros. Integrate local model runtimes and app features end to end. Work agent-natively as your default, running agents in parallel with your own review and guardrail discipline.

Build the core gateway: a unified, OpenAI-compatible API in front of multiple providers (OpenAI, Anthropic, Google, plus self-hosted and OSS models). Own provider routing and reliability: load balancing, automatic failover, and cost and latency-aware routing. Build billing and metering that is correct, not approximate: per-request token accounting, usage ledgers, cost attribution per team, user, and key, budgets, and spend limits. Ship org controls: API key management, per-team and per-user quotas, rate limiting, and RBAC. Handle streaming and performance: low-overhead proxying, streaming responses, connection handling, and caching where it helps. Contribute to the Jan Agent and connect it to the router: route its model and tool calls through the gateway, and make agent traffic first-class in metering, controls, and observability. Make deliberate speed-versus-correctness calls: move fast where iteration is cheap, refuse to cut corners where a bug means a bad charge or a leaked key, and pay down debt on your own initiative.
