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.
