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.

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, and automation testing setup. 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.
