Full Description

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 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 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 (MedCon-1) outperforms GPT-4.5, Gemini, Claude on clinical reasoning tasks Sully requires A-players capable of 4 months = 1 year output. This role is structured as a Contract-to-Hire position with a 60-day trial period. Sully.ai maintains an exceptionally high performance bar, and this structure ensures mutual alignment before transitioning to full-time What You’ll Do • Build and optimize core research infrastructure: evaluation pipelines, agent workflows, hallucination detectors, coding benchmarks, and research→production integrations. • Design, implement, and scale agentic systems across backend, frontend, and model integrations, collaborating closely with research and co-founders. • Own reliability, observability, and performance across agents (logging, tracing, instrumentation, safety checks). • Ship research-proven features into production within 7 days, end-to-end. • Develop shared tools, SDKs, and internal products that accelerate iteration across Research, QA, and Engineering. What You Must Bring • Senior-level full-stack engineering 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. First-Month Focus • Audit all cross-agent flows for UI/UX consistency, correctness, and performance gaps. • Implement shared components, typed schemas, and contract-driven interfaces for reliability. • Establish instrumentation for frontend performance, agent consistency, latency, and model round-trip tracing. • Improve or replace brittle evaluation or agent pipelines identified during onboarding. • Partner with Research to productionize at least one new capability. 90 Day OKRs • Deliver production-grade agentic workflows with <5% error rates across evaluation benchmarks. • Launch a cross-agent design system + SDK adopted by at least 2 internal teams. • Establish a weekly deploy + measure cadence with performance dashboards, latency budgets, and error budgets. • Reduce agent latency and failure rates across at least two high-volume workflows. • Ship multiple research-to-production integrations with measurable CSAT or accuracy gains. Who Thrives Here • Entrepreneurial to your core: You think in outcomes, thrive in chaos, and take ownership without limits • Mission-obsessed: You’re here to save lives, not just ship features — patients and doctors are your why. • Impact-driven & fast-moving: You sprint toward hard problems and ship with sharp judgment. • Elite teammate: You raise the bar through high standards, direct feedback, and craft excellence.
