About the Role
Join a small team at a seed-stage AI company building voice agents for customer service, sales, and operations. You will own product features end to end across applied AI, agent configuration, integrations, and the underlying systems, delivering improvements that address real customer problems.

Develop and optimize voice agents for speed, reliability, and quality.
Extend agents to support calls, messaging, and email with shared memory and state.
Build memory systems that help agents reason across customer interactions and workflows.
Improve observability and tracing so teams can understand and investigate unsuccessful calls.
Help agents choose the appropriate communication channel for each interaction.
What We're Looking For
Production experience owning product features across frontend and backend, including distributed systems.
Strong software fundamentals, product judgment, and a bias toward action and business impact.
Production backend experience with TypeScript, Python, or FastAPI, and experience with React or similar frontend technologies.
Experience with realtime audio or voice infrastructure, and with LLMs, AI agents, or agentic systems in production.
Experience building asynchronous or event-driven systems with complex state, and using PostgreSQL, Redis, or similar data stores.
Experience with AWS, GCP, or Azure. Familiarity with workflow orchestration, observability, and communication integrations is useful.
Relevant stack includes TypeScript, React, Vite, TanStack, Node.js, Python, FastAPI, PostgreSQL, Redis, Temporal, and AWS.
