Full Stack AI Engineer (TypeScript)

We're looking for a TypeScript Engineer who operates across the full stack and understands how to build real AI products, not just integrate an API, but architect pipelines, manage retrieval, wire up agents, and ship something people actually use.

Key Requirements:

• Strong TypeScript proficiency across both frontend and backend (4+ years in production)
• Solid experience with React (v18/19) and NestJS or equivalent Node.js framework
• Hands-on experience building with LLMs — LangChain, RAG pipelines, vector databases, or tool/agent frameworks
• Familiarity with Tauri, Electron, or any desktop application shell (Tauri v2 preferred)
• Comfort with real-time architectures (Socket.IO, WebSockets)
• A strong GitHub portfolio demonstrating AI or full-stack product work
• Experience with modern testing practices; mutation testing (Stryker) is a strong plus

Key Responsibilities:

• Design and build backend services using NestJS 11 and Node.js 22 with Bun as the runtime toolchain
• Develop responsive, performant frontend interfaces using React 19, MUI 7, Zustand, and Vite 7
• Build and maintain LLM application pipelines using LangChain and the MCP SDK, including RAG workflows with ChromaDB 3 and HNSW indexing
• Integrate and maintain the Tauri v2 desktop shell for cross-platform packaging and native OS interaction
• Implement real-time features using Socket.IO
• Write comprehensive tests across unit (Vitest 3), end-to-end (Playwright), and mutation (Stryker) layers
• Contribute to architecture decisions and technical direction of the product
