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.

• We are hiring multiple Heads of Engineering to own and scale core product domains: Consultant, Integrations, Mobile, 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.

• 7+ years of startup/founding experience in a high-growth early-stage start-up, or founder/co-founder experience bringing SaaS products from ideation to enterprise scale.

• Experience in high-intensity environments such as YC-backed startups, early-stage companies, or zero-to-one teams where speed and judgment matter.

• Comfort with ambiguity. You turn incomplete product direction into clear technical plans and ship without a heavy process.

• Bias toward leverage and simplicity. You choose durable solutions and know when to optimize versus when to ship.

• 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.

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.
