-   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
