Head of Engineering

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.

What You’ll Do:

We are hiring multiple Heads of Engineering to own and scale core product domains: Scribe, Consultant, Integrations, and Platform. Each role has full technical and execution ownership for its surface area.

• Own end-to-end engineering execution for your domain, from architecture and roadmap through delivery and reliability.
• Drive step-function latency reductions, targeting at least 50 percent improvements across note generation and decision-support workflows where applicable.
• Design and operate robust observability, metrics, and model-selection systems to ensure consistent performance at scale.
• Lead domain-specific execution rituals including daily and weekly standups, backlog ownership in Linear, and tight cross-functional coordination.
• Translate product goals into clear dependencies, timelines, and deliverables to keep teams unblocked and shipping.
• Operationalize continuous quality evaluation pipelines to improve accuracy, completeness, and reliability of outputs.
• Set and enforce engineering best practices across your stack, including code quality, reviews, on-call standards, and operational rigor.

What You Must Bring

• Founder-level ownership mindset. You operate like the business depends on your decisions and execution.
• Senior, hands-on engineering ability. You actively design systems, write and review production code, and set the technical bar by example.
• Experience in high-intensity environments such as YC-backed startups, early-stage companies, or zero-to-one teams where speed and judgment matter.
• Strong systems thinking with a proven record of improving latency, throughput, and reliability in real production systems.
• Comfort with ambiguity. You turn incomplete product direction into clear technical plans and ship without heavy process.
• High quality standards. You enforce clean abstractions, disciplined reviews, and operational rigor while moving fast.
• Bias toward leverage and simplicity. You choose durable solutions and know when to optimize versus when to ship.
• Clear communicator who can align engineering, product, and leadership with minimal overhead.
• Nice-to-have:
  • Experience with FHIR/HL7 or EHR systems.
  • Background in real-time or near-real-time streaming, diarization, or structured-output pipelines.
  • Experience supporting front-end or extension-based integrations (web, mobile, browser extension).

First-Month Focus

• Take full ownership of the assigned engineering domain.
• Ensure end to end observability and alerting for core workflows.
• Define the domain’s key performance, reliability, and quality metrics.
• Identify and ship at least one high impact improvement.
• Establish execution cadence, priorities, and quality standards.

If you’ve ever said, “I want to do work that actually matters”, this is it. Let’s build something life-changing, together.

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.
