About this role

ABOUT ON ME Humans have given each other gifts since the dawn of time. For gratitude, for friendship, and for love. In today’s society, gifting has become harder and much more wasteful, as it’s become nearly impossible to know exactly what someone wants, when you just want to show that you care. On Me is revolutionizing gifting by rebuilding it for the mobile and Instagram era. Traditional gift cards are impersonal and rigid, usually sold by an old and wealthy megacorp. We make it easy to send a personalized, media-rich gift that’s spendable across brands, fits someone’s hobbies, and drops straight into their mobile wallet for tap‑to‑pay. Check out our live experience at onme.com http://onme.com. We’re a small startup from Google, Apple, and Stripe moving fast on a massive category and have raised $8M from top‑tier investors like NFX, Lerer Hippeau, Focal VC, and Mastercard. Since launching in November 2024, On Me has been featured in Tech Crunch, Fortune, and The Wall Street Journal. In 2025, we sustained over 40% growth month over month throughout the year, and the trend shows no sign of stopping. In 2026, we're doubling down on making every gift feel magical end‑to‑end and building an amazing consumer product. You'll help us build world-class iOS and Android apps that people love. If you want meaningful ownership, clear consumer product impact, and the chance to set engineering standards early, this is it.

WHAT YOU’LL DO As a mobile software engineer, you'll be the fourth engineer at a tiny startup, working closely with the whole team to design and build the native mobile experiences that power our gifting platform. You'll own our iOS and/or Android apps from architecture to pixel‑perfect UI, building polished, performant experiences backed by clean API integrations. Your work will include thinking through user journeys, edge cases, loading and error states, and optimizing for performance across devices. You'll have end-to-end ownership of critical mobile surfaces, driving both product and engineering decisions that shape the future of digital gifting.

REQUIREMENTS - 5+ years of experience building and shipping native mobile apps. - Proficiency in Swift (iOS) and/or Kotlin (Android), with strong experience in at least one and working knowledge of the other. - Strong product and UX mindset: you think from the user's point of view and care about end‑to‑end flows, not just screens. - Deep understanding of mobile platform conventions, lifecycle management, and performance optimization. - Experience with mobile CI/CD, automated testing, and release management (TestFlight, Play Console). - Solid understanding of API integration, data modeling, and how systems fail in practice. - Ability to take ownership of projects from vague problem → design → implementation → launch and iteration. - Strong communication and collaboration skills in a fast-paced startup environment.
