Head of Engineering, Platform

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.

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
