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.
