About The Position

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.

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.

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.
