At Sully.ai, We’re Building the Most Impactful Healthcare Company on Earth

We believe that access to a great doctor is a basic human right. Today, that’s not a reality. Delays, misdiagnoses, administrative chaos, and burnout plague the system.

Our Mission: One Human, One Doctor. We build AI teammates that augment clinicians — scribes, nurses, receptionists, translators — all powered by our own world-class models and deployed in real-world care.

Design, implement, and optimize core components across frontend, backend, and model integrations, while driving engineering direction in close collaboration with our co-founders.

Senior-level full-stack experience in React, TypeScript, and Node.js

Proven ability to design, ship, and scale LLM-powered applications.

Expertise in API design, streaming, and CI/CD pipelines.

Track record of building reliable systems with measurable performance and error budgets.

Key Results (First 90 Days)
