About Us
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 enable our customers to staff 30% of their workforce with AI by creating a shared agent architecture for scale and efficiency. All powered by our own patented, 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.

• Strong cloud infrastructure background (AWS, GCP, or Azure).

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

• Audit current cross-agent flows for UI/UX cohesion.

• Implement shared components and typed contracts for reliability.

• Establish instrumentation for frontend performance and model round-trip tracing.
