Head of Engineering, Platform

Job description

About Us At Sully.ai http://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. About the Role Sully automates clinical documentation at the point of care. Real-time ambient listening, structured medical notes, and agentic AI workflows embedded in the EHR. We're live in 270+ clinics, have processed 2M+ real physician-patient encounters, and run on custom medical models that outperform GPT, Claude and Gemini on clinical benchmarks. We're not a wrapper company. We're hiring a hands on Head of Engineering, Platform to take full ownership of Sully's platform domain: the agentic scribe pipeline, copilot backend, AI workers, EHR integration layer, and the infrastructure that ties them together. Platform is the engine: Every note generated, every EHR sync, every real-time AI action in a patient visit runs through what you build. You will be the DRI for platform architecture, reliability, latency, and execution, from design through on-call. ─── What You'll Own • End-to-end platform engineering: Agentic scribe pipeline, copilot-backend, AI workers, EHR sync, multi-tenant infrastructure, and real-time audio processing • Drive-function latency improvements: targeting 50%+ cuts across AI generation workflows (note gen, decision support, real-time agent actions) • Observability, alerting, and model-selection systems that give real signal at scale • Continuous quality pipelines: accuracy, completeness, and reliability of every AI output across all orgs and EHR integrations • Execution cadences: OKRs, standups, backlog ownership in Linear, tight coordination with Scribe, Receptionist, Integrations, and Research • Engineering bar across the stack: architecture decisions, PR reviews, on-call standards, and operational rigor • Platform roadmap translation: from product goals and research breakthroughs to clear technical plans with real timelines ─── What We're Looking For • You've built and shipped real platform systems: Distributed architecture, async pipelines, real-time audio/ML workloads, multi-tenant backend. Not just CRUD services. You can go deep on system design and come back with something that actually scales. • You still write code: Player-coach. We evaluate hands-on engineering depth directly. • You've led engineers: made them sharper, not just coordinated their sprints. Small team is fine. Impact is what matters. • You've operated in high-intensity environments: YC-backed, seed-stage, zero-to-one. Speed and judgment over process. You've felt what it means when the platform is down and the whole company is waiting. • Healthcare or high-reliability software experience is a strong signal: You understand what it means to build systems where errors have real consequences. • Ambiguity is your operating system: You convert incomplete direction into clear plans and shipped systems. No hand-holding needed. ─── First 90 Days • Take full ownership of the platform domain: establish yourself as the DRI for architecture, reliability, and delivery decisions • Ensure end-to-end observability and alerting for core platform workflows: note generation pipeline, EHR sync, AI worker health, and real-time audio processing • Define key platform metrics: p50/p99 latency, pipeline completion rate, EHR sync reliability (target ≥98%), error rates by service • Identify and ship at least one high-impact improvement: latency reduction, reliability fix, or architecture simplification • Establish execution cadence: OKRs, on-call standards, and quality benchmarks across the platform stack ─── Why Sully • Real Product Market Fit: 270+ clinics live, 2M+ encounters processed, physicians choosing it every day in patient visits • Custom medical models: we build our own and they win on clinical benchmarks • The platform challenges are real and immediate: sub-second AI inference, multi-EHR sync, real-time audio pipelines, distributed agentic workflows at scale • You're replacing a genuinely broken workflow (manual documentation = physician burnout), not adding an AI feature • Small team, large surface area, high ownership: If you want to own the platform infrastructure of a company defining how AI works in healthcare, this is it Why Join Sully.ai http://Sully.ai? 🔥 Revolutionizing the antiquated $800B+ Healthcare market 🧠 60%+ Ex-founders who have built, scaled, exited. We hire A-players ⚡️ Speed matters: we operate with urgency, autonomy, and ownership 🧪 You’ll work on real, first-of-their-kind problems at the edge of AI and medicine ❤️ Your work directly unlocks doctors to reclaim their time, and patients get better, faster care Sully.ai is an equal opportunity employer.
