Head of Engineering, iOS

# **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. ### **About the Role** We are seeking a **Head of Engineering, iOS** to own and scale our iOS mobile platform. You will lead end-to-end engineering execution for our iOS app, driving step-function improvements in performance, reliability, and user experience while establishing technical excellence across the mobile stack. ### **Key Responsibilities** * Own end-to-end engineering execution for iOS, from architecture and roadmap through delivery and reliability. * Drive step-function performance improvements, targeting at least 50% reductions in app launch time, memory usage, and crash rates. * Design and operate robust observability, metrics, and automated testing systems to ensure consistent performance at scale. * Lead iOS execution rituals including daily and weekly standups, backlog ownership in Linear, and tight cross-functional coordination with Product, Design, and Backend teams. * Translate product goals into clear dependencies, timelines, and deliverables to keep teams unblocked and shipping. * Drive mobile EHR integration excellence, ensuring seamless integration with Epic Haiku, Epic HyperSpace, and other mobile EHR platforms. ### **Hard Requirements** * **Founder-level ownership mindset.** You operate like the business depends on your decisions and execution. * **Senior, hands-on iOS engineering ability.** You actively design systems, write and review production Swift code, and set the technical bar by example. * **Deep iOS platform expertise.** 7+ years of iOS development with Swift/SwiftUI, UIKit, and modern iOS architectures. Experience shipping consumer-grade iOS apps to the App Store at scale. * **Experience in high-intensity environments** such as YC-backed startups, early-stage companies, or zero-to-one teams where speed and judgment matter. * **Mobile leadership experience.** You've led iOS teams (3+ engineers) and own mobile engineering processes, release management, and cross-platform coordination. * **Comfort with ambiguity.** You turn incomplete product direction into clear technical plans and ship without 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 iOS engineering.** Establish yourself as the DRI for all iOS architecture, quality, and delivery decisions. * **Ensure end-to-end observability and alerting** for core iOS workflows including note generation, medical assistant features, and EHR sync. * **Define key performance, reliability, and quality metrics** for the iOS app (crash-free rate, memory usage, app launch time, user satisfaction scores). * **Identify and ship at least one high-impact improvement** — whether performance optimization, memory leak fix, or critical user experience enhancement. * **Establish execution cadence, priorities, and quality standards** including iOS release process, QA workflows, and automated testing infrastructure. * **Audit and improve iOS technical debt** including architecture issues, memory leaks (IOS-307), and automation testing setup (E-6337). 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. ### ### **Why Join [Sully.ai](http://Sully.ai)?** 🔥 Revolutionizing the antiquated $800B+ Healthcare market 🧠 50%+ of us are ex-founders.
