Join Jetty, building the first AI functional health doctor and coach, starting with people living with chronic illness. As the first full-time mobile engineering hire, you'll own the entire Jetty mobile experience (a live product already in real users' hands) and shape it into something clear, calm, and trustworthy — even when health data is messy, sensitive, and deeply personal.
• Own the mobile product end-to-end — design, build, and ship user-facing features across the full Jetty iOS app from concept to production
• Transform complex inputs into trustworthy experiences — translate voice, text, passive health signals, and AI-generated outputs into UI flows that feel intuitive and reliable
• Set the bar for mobile craft — take direct ownership of performance, reliability, and accessibility across the app
• Integrate AI thoughtfully — embed AI-driven insights and health summaries while handling uncertainty, latency, and failure states in ways that maintain user trust
• Instrument and iterate — implement mobile analytics across key events, flows, and retention signals to close the feedback loop and improve the product quickly
• Shape product and architecture decisions — partner directly with Design, Backend, and AI leadership to influence product evolution and establish technical foundations
• 2-5+ years of experience building and shipping mobile apps, ideally in startup or fast-moving product environment
• Strong iOS fundamentals (Swift, UIKit and/or SwiftUI) with clear track record of owning features from idea to launch
• Product instincts that go beyond screens — thinks in flows, states, and edge cases, catches gaps before users do
• Architectural judgment to make pragmatic tradeoffs — knows when to optimize for speed and when to invest in maintainability
• Comfort navigating ambiguity — can pick up loosely defined problem, make sound decisions with incomplete information, and ship something solid
• Genuine high bar for craft — notices small details that make product feel polished and trustworthy
• Android experience (Kotlin / Jetpack Compose) or prior cross-platform development
• Experience with design systems or reusable component libraries
• Hands-on experience with audio/voice input, background processing, push notifications, or real-time UX patterns
• Prior work in privacy-sensitive domain — health, finance, or similar — where data handling and user trust carry real weight
• Meaningful equity — early enough that ownership stake actually means something
• Work on something that matters — chronic illness affects hundreds of millions of people
• First full-time mobile hire — real influence over technical culture, tooling choices, and how engineering team scales
• Work directly with founding team (former senior AI leader from Palantir and former venture investor from NEA)
• Backed by top seed investor in NYC with $2M+ funding
• Product is live, not theoretical — shipping to real users from day one with immediate feedback loops
• Competitive salary + meaningful equity
