Application Engineer

JOB DESCRIPTION

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.

JOB REQUIREMENT

Full-stack engineer, strong in React and Node.js.
Hands-on experience building and shipping Tauri apps.
Working knowledge of Rust.
Desktop app development and cross-platform distribution experience.
Solid Linux skills: packaging, distribution, and environment quirks.
Proven ownership of app packaging, builds, and release pipelines.
An agent-native default workflow and the judgment to hand-write critical code when it matters.
Comfortable with full ownership, ambiguity, and shipping fast.
 
Nice to Have
Familiarity with the Jan.ai ecosystem or other OSS desktop and LLM tooling.
Experience with auto-update, code signing, and app store or package-manager distribution.
Local model or inference runtime integration experience.

WHAT'S ON OFFER

Collaborate with a world-class research team on meaningful, high-impact projects
Own and shape the core training code infrastructure used daily by the team
Work on real models, real data, and real scale - not toy problems
Help bridge the gap between research velocity and engineering quality
Flexible work environment with a culture that values depth, clarity, and curiosity

Backend Engineer

Ho Chi Minh - Viet Nam

Product

  • Typescript

  • AI

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.
