ABOUT THE ROLE Join a small engineering team building voice AI agents for customer-facing business workflows. You will own projects end-to-end, shaping technical decisions and shipping reliable systems across applied AI, real-time audio, and distributed infrastructure. WHAT YOU'LL DO - Build fast, reliable voice AI systems, including retrieval-augmented generation, dynamic model routing, and testing transcription systems before production rollout. - Design and operate distributed call scheduling systems that handle concurrent workloads, race conditions, time zones, retries, and provider limits. - Extend agents to support calls, messaging, and email with shared memory and state across real-time and asynchronous conversations. - Develop memory and reasoning systems that preserve context throughout customer workflows. - Build AI tools that configure agents, help diagnose issues, and connect with business systems such as CRMs, calendars, and email. - Improve observability and resilience so failures across calls, workers, and providers can be traced and addressed. WHAT WE'RE LOOKING FOR - Experience shipping and owning product software end-to-end, including distributed systems in production. - Production experience with Python, FastAPI, or TypeScript, and data stores such as PostgreSQL or Redis. - Experience with real-time systems, audio processing, or voice infrastructure, plus practical work with LLMs, AI models, or agentic systems. - Understanding of concurrency, race conditions, load balancing, and fault tolerance, as well as cloud infrastructure on AWS, GCP, or Azure. - Familiarity with workflow orchestration or message queues, and observability tools such as OpenTelemetry or Honeycomb. - Comfort working across backend and, where useful, frontend systems such as React. Strong software fundamentals, independent problem-solving, and a focus on customer and business outcomes are important. - Experience level may range from 2 to 10 or more years, with demonstrated owner…
