About the Role

Join a small product engineering team building AI voice and agent systems for customer-facing workflows. You will own features end to end, work directly on customer problems, and help shape how these systems handle complex interactions reliably.

What You'll Do

Build tools that help configure AI agents, troubleshoot issues, connect external systems, and answer questions about customer workflows.
Develop and optimize voice agents for speed, reliability, and high-quality interactions.
Extend agent capabilities across calls, messaging, and email, with shared memory and state.
Build memory systems that help agents reason across complete customer journeys.
Improve observability and tracing so issues in agent interactions are easy to understand.
Help agents select the most appropriate communication channel for each interaction.

What We're Looking For

At least 3 years of experience building and owning production product features across frontend and backend, including distributed systems.
Production experience with Python, FastAPI, or TypeScript for backend systems, and experience building React frontends.
Experience with real-time audio or voice infrastructure, AI agents or LLM-based systems, and asynchronous or event-driven systems with complex state.
Experience with PostgreSQL, Redis or similar data stores, and AWS, GCP, or Azure.
Familiarity with workflow orchestration, scheduling, communication integrations, and observability tools is valuable.
Strong software fundamentals, product sense, and a bias toward action and business impact.
Relevant technologies include TypeScript, React, Vite, TanStack, Node.js, Python, FastAPI, PostgreSQL, Redis, Temporal, and AWS.
