About the role

About the Role

Join a small engineering team building voice AI agents for customer-facing business workflows. You will own projects from product decisions through architecture and production delivery, helping make real-time AI interactions reliable and useful.

What You'll Do

  • Build reliable voice AI systems, including retrieval-augmented generation, dynamic model routing, and testing new transcription systems before release.
  • Design and operate distributed call scheduling systems that handle concurrency, time zones, retries, provider limits, and failures.
  • Extend agents across voice and other communication channels, maintaining shared context across real-time and asynchronous conversations.
  • Develop memory and reasoning capabilities that help agents maintain context through customer workflows.
  • Build AI-powered tools for configuring agents, troubleshooting issues, and connecting to business systems.
  • Improve observability and resilience so issues can be traced to their root causes.

What We're Looking For

  • At least 2 years of relevant experience building and shipping product software, including owning distributed systems in production and delivering projects end to end.
  • Production experience with Python, FastAPI, or TypeScript, and data stores such as PostgreSQL or Redis.
  • Experience with distributed systems, real-time systems, audio processing, voice infrastructure, or production AI and agentic systems.
  • Familiarity with cloud infrastructure such as AWS, GCP, or Azure.
  • Experience with workflow orchestration or message queues, frontend development, and observability tools is useful.
  • Strong software fundamentals, a bias toward action, and an interest in business outcomes and reliable AI products.
  • Relevant technologies include LiveKit, Bun, Node.js, Fastify, React, Temporal, and OpenTelemetry.
