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 .
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.
Who you are
You're perfect for this role if you're a mobile engineering expert who wants to own the native app experience end to end. You love crafting polished, performant iOS and/or Android apps that delight real users. You care deeply about the quality and craft of what you build, and why you build 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.
Key Responsibilities
- Design, implement, and ship native iOS and/or Android features using Swift and Kotlin.
- Build high-quality, fluid mobile UIs with attention to polish, animation, responsiveness, loading, and error states.
- Architect and evolve our mobile codebases for maintainability, testability, and performance.
- Integrate with backend APIs and collaborate on API design to support mobile use cases.
