• Develop and optimize voice agents for speed, reliability, and quality.

• Extend agent interactions across calls, messaging, and email, with shared memory and state.

• Improve observability and tracing so teams can understand and resolve agent failures.

• Help agents select the right communication channel for each interaction.

What We're Looking For

• 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.
