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.

Our Traction: 450+ organizations signed in 16 months; AI agents cut admin by ~2.8 hours daily and reduce onboarding 85%; 5M+ Clinical Tasks completed to date, serving 36+ specialties. Raised $25M from YC, Eric Yuan, Amity, Semper Virens. Patented AI architecture (Med Con‑1)
outperforms GPT‑4.5, Gemini, Claude on clinical reasoning tasks.

Sully requires A‑players capable of 4 months = 1 year output.

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

• 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

• Deliver end‑to‑end tested, production‑grade agentic workflows with
