At least 3 years of professional software engineering experience, including production ownership of distributed systems.
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.
Experience with workflow orchestration, communication integrations, or observability tools is useful.
