## Description

### About the Role

Join a small, fast-moving engineering team building voice AI agents for customer-facing workflows. You will own projects end-to-end across applied AI, real-time audio, and distributed systems, helping turn complex customer needs into reliable production software.

### What You'll Do

- Build reliable voice AI systems, including retrieval-augmented generation, dynamic model routing, and evaluation of transcription systems.

- Design and operate a distributed call scheduler that manages concurrency, race conditions, time zones, retries, and provider limits.

- Extend agents across voice, messaging, and email, maintaining shared memory and state across real-time and asynchronous conversations.

- Develop memory and reasoning systems that preserve context through customer workflows.

- Build AI-assisted tools for configuring agents, diagnosing issues, and connecting to business systems such as CRMs, calendars, and email.

- Improve observability and resilience by making failures traceable and ensuring graceful recovery when calls, workers, or providers fail.

### What We're Looking For

- Production experience building and owning distributed systems, with a track record of shipping product software and delivering projects end-to-end.

- Strong software fundamentals and experience with Python, FastAPI, or TypeScript in production systems.

- Experience with real-time systems, audio processing, or voice infrastructure, and with production LLM, AI model, or agentic systems.

- Experience with PostgreSQL, Redis, or similar data stores, plus cloud infrastructure on AWS, GCP, or Azure.

- Ability to design or debug systems involving concurrency, load balancing, and fault tolerance.

- Familiarity with tools such as LiveKit, Temporal, message queues, workflow orchestration, React, and observability platforms is valuable.

- Independent, action-oriented approach, sound judgment about code quality and reliability, and a focus on team and customer outcomes.
