Moonshot is the “Robinhood for DeFi”—an iOS and Android app that lets anyone trade cryptocurrencies on-chain through a user-friendly interface.
Since our launch in July 2024, we’ve attracted 2M+ users.
Our mission: Make moonshots possible for everyone.
Our vision: Make a world where life-changing financial outcomes are within everyone's reach.
Everyone on our team is both a decision-maker and an implementer—united by a sense of urgency and driven by the conviction that our work can transform global finance. If you thrive on curiosity, welcome tough challenges, and aspire to leave a meaningful mark on the world, Moonshot is the place for you. You’ll run toward the hardest problems alongside high-caliber teammates who consistently push each other to excel and who share your dedication to shaping the future of decentralized finance.
This role is full-time, preferably located in NYC. Open to remote for the right candidate.

Implement and maintain automated testing (unit, widget, integration) and help define release and QA processes.
Collaborate with Product and Growth to integrate analytics, A/B testing, feature flags, and event tracking directly into the app.
Partner with Backend/Platform engineers on API design, data models, error handling, and resilience (retries, fallbacks, offline behaviour).
Lead by example through code reviews, design docs, and mentorship, raising the bar for mobile excellence.
Participate in on-call rotations for mobile-related incidents and drive root-cause fixes.
6–10+ years of professional mobile development, ideally 3+ years of Flutter in production or otherwise React Native, Kotlin, Swift
Experience owning large-scale consumer apps end-to-end, ideally in fintech, trading, or similarly demanding domains.

Demonstrated experience building or leading design systems / UI libraries in Flutter or other frameworks.
Solid engineering fundamentals: testing, CI/CD for mobile, monitoring, and release management.
Strong collaboration skills and experience mentoring other engineers.
Experience with real-time data (WebSockets/streams) and highly interactive UIs.
Exposure to growth-focused mobile work: experiment frameworks, deep links, attribution.
Crypto/DeFi or trading experience, or other high-frequency transactional apps (sports betting, brokerage, etc.).
NYC preferred (with periodic in-person sprints).
Remote-friendly within NAMER; travelling ~1wk/qtr
