Senior Backend Developer (NodeJS)

We’re a reimagining how specialty clinics operate through advanced voice AI and multi-agent systems. Our platform powers intelligent, real-time phone and SMS conversations for healthcare, blending state-of-the-art AI with secure, scalable backend infrastructure. Join a small, ambitious team where your work directly shapes the future of patient engagement and care delivery.

What You’ll Do

• Architect and build scalable backend services in Node.js and TypeScript

• Design and integrate RESTful and GraphQL APIs (internal and third-party)

• Develop and optimize real-time voice AI systems, including telephony (Twilio, WebRTC) and conversational agents

• Contribute to the design and implementation of multi-agent AI systems for complex, stateful healthcare workflows

• Work with LLMs and help shape our AI engineering frameworks (tool calling, retrieval, orchestration)

• Optimize deployments and infrastructure on GCP (Kubernetes, containers)

• Improve CI/CD pipelines (Cloud Build, GitHub Actions)

• Collaborate with frontend, product, and AI teams to ship features fast

• Champion best practices for performance, scalability, and security

What We’re Looking For

• 5+ years of backend experience with Node.js and TypeScript

• 3+ years building real-time communication systems (WebRTC, WebSockets, or telephony)

• Experience with voice AI, conversational agents, or multi-agent system architectures

• Experience in healthcare software (HIPAA compliance) or deep real-time systems expertise (both is a plus)

• Startup mindset: You thrive in fast-paced, high-ownership environments
