Head of Engineering, Platform

Job Overview

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.

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?

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
