Our client is reimagining how specialty clinics run - from phone calls to follow-ups - using multi-agent systems, LLMs, and real-time voice AI. Their platform powers intelligent conversations via phone and SMS, helping front-desk staff become instantly scalable.
They’re looking for a
Founding AI Engineer
to join their small, high-caliber team and architect the technical backbone for live telephony pipelines, agent orchestration, and LLM workflows - all while building for real-world adoption in a high-trust, regulated environment.
What you’ll build:
Backend infrastructure in Node.js/TypeScript that scales with demand
Real-time voice AI systems using WebRTC, Twilio, and AI agents
Agent orchestration layers - from tool-calling and retrieval to complex state management
APIs (GraphQL/REST) that connect frontend, agent infra, and third-party data
HIPAA-compliant systems on GCP (Kubernetes, containers, CI/CD pipelines)
Telephony event flows, memory modules, routing, and feedback loops for live LLM performance
What they’re looking for:
5+ years backend experience (Node.js/TypeScript preferred)
Real-time systems: WebRTC, WebSockets, or Twilio
Deep interest or experience in agent systems and voice AI
Experience in regulated domains (healthcare a plus, not required)
A builder mindset - bias to action, ownership, and getting things live
If you're looking for a role where infrastructure meets intelligence - and where your work directly improves how care is delivered - this could be the one.
