Head of Engineering

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 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. ABOUT THE ROLE - 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. KEY RESPONSIBILITIES - 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. HARD REQUIREMENTS - 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. KEY RESULTS (FIRST 90 DAYS) - 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.
