**Join us in building the most efficient, AI-powered mental healthcare system.**
We’re a YC-backed company revolutionizing telepsychiatry—not with AI for diagnostics, but with AI-driven operations that actually make patient care faster, smoother, and more accessible.

We’re hiring top-tier engineers who thrive in high-velocity, AI-first environments and want to build technology that meaningfully improves lives. If you love shipping fast, working with AI, and solving hard problems, keep reading. 👇

Why This Role?

  • You’ll own the architecture for a next-gen, AI-driven healthcare system.
  • You’ll design event-driven systems that integrate LLM-powered automation across scheduling, billing, and patient interactions.
  • You’ll scale a backend that supports thousands of patients while maintaining HIPAA compliance & security.
  • You’ll shape the future of AI in healthcare, working directly with the founding team.

What You’ll Work On

  • Architecting and implementing a highly-scalable, event-driven backend using Node.js, Supabase (Postgres), and AWS.
  • Building real-time, AI-powered patient and provider workflows that optimize scheduling, intake, and operational efficiency.
  • Designing robust event pipelines to capture and structure rich operational data (call transcripts, scheduling metadata, etc.).
  • Ensuring high availability, reliability, and security—handling PHI data while keeping everything fast and seamless.
  • Collaborating with our AI and front-end teams to build an integrated, LLM-powered care delivery system.

What We’re Looking For

  • 5+ years of experience in backend engineering (Node.js, TypeScript, Postgres).
  • Expertise in event-driven systems, message queues, or stateful data architectures.
  • Experience with real-time data processing (e.g., webhooks, Kafka, or event sourcing).
  • Comfortable working with LLMs—you don’t need deep AI expertise, but you should be excited to build AI-first systems.
  • Strong security and compliance mindset (HIPAA or other regulated environments is a huge plus).

What We Offer

  • $70-200K salary + equity (commensurate with experience).
  • A high-velocity team—you will ship and own your work.
  • A mission that matters—we’re solving real healthcare problems at scale.
  • Deep AI integration—you’ll be at the frontier of operational AI in healthcare.
