• Production backend experience with Python, FastAPI, or TypeScript, plus product development across frontend and backend.
• Strong software fundamentals, product judgment, and a bias toward action and measurable business outcomes.
• Experience with real-time audio or voice infrastructure, AI agents or LLMs, and asynchronous or event-driven systems with complex state.
• Production experience with PostgreSQL, Redis, or similar data stores, and cloud infrastructure such as AWS, GCP, or Azure.
• Technology includes TypeScript, React, Vite, TanStack, Node.js, Python, FastAPI, PostgreSQL, Redis, Temporal, and AWS.
