About the job

You’ll work across the JavaScript and TypeScript layer of our local AI stack. Depending on the project, you might build user-facing applications (mobile or desktop) or contribute to the platform layer that bridges our C++ inference engines with the app ecosystem. Either path puts you at the heart of making local AI usable: whether you’re crafting polished product experiences or building the SDK and bindings that other developers rely on.

Responsibilities

  • Own React (Expo/Electron) app development with clean, modular architecture
  • Build UI using modern React stack (TypeScript, RN Navigation, Zustand/Recoil/Jotai)
  • Implement local first / local only apps
  • Integrate mobile apps with distributed systems, local inference, and p2p layers
  • Strong experience with REST/WebSockets, async flows, and secure data storage
  • Ability to build native modules (iOS/Android) when needed (with some help)
  • Good understanding of offline-first systems, caching, and performance
  • Comfortable integrating SDKs (payments, crypto, AI models, etc.)
  • Write reliable code: unit tests, E2E tests (Maestro/Appium/Playwright)
  • Experience with TypeScript across stack (frontend + backend)
  • Bonus: experience with distributed/P2P APIs, on-device ML, cryptography

Qualifications

  • 5+ years of experience in Fullstack development
  • Expert-level proficiency in Node.js/JavaScript for backend development and React frontend framework
  • Experience with performant data handling on constrained devices (via SQLite or similar)
  • Proven experience building and scaling distributed systems or event-driven architectures
  • Experience with containerization technologies (Docker) and orchestration platforms (Kubernetes)
  • Proficiency with databases, and a deep understanding of data modeling and optimization
  • Solid understanding of networking, security principles, and best practices for production systems
  • Experience with real-time data streaming and RPC implementations
  • Ability to work independently in a remote environment and communicate effectively across time zones

Nice to have

  • Experience with peer-to-peer technologies (Hyperswarm, libp2p, WebRTC) or similar distributed communication protocols
  • Familiarity with AI/ML inference APIs and OpenAI-compatible endpoints
  • Previous experience building AI SaaS or PaaS platforms
  • Knowledge of GPU resource management and ML framework infrastructure
  • Understanding of WebAssembly or edge computing paradigms
  • Contributions to open-source projects in relevant domains
