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

Extend agents to support calls, messaging, and email with shared memory and state.

What We're Looking For

At least 3 years of professional software engineering experience, with production experience across frontend and backend development.

Experience building and owning distributed systems, asynchronous or event-driven workflows, and complex state management in production.

Production backend experience with Python, FastAPI, or TypeScript, and frontend experience with React or TanStack.

Experience with real-time audio systems or voice infrastructure, and with LLMs, AI agents, or agentic systems in production.

Experience with PostgreSQL, Redis, or similar data stores, and cloud infrastructure such as AWS, GCP, or Azure.

Familiarity with workflow orchestration tools such as Temporal, communication integrations, and observability tools such as OpenTelemetry.

Strong software fundamentals, product sense, and a bias toward delivering customer and business outcomes.
