Platform Engineer
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.
The Opportunity
As a Platform Engineer at Moonshot, you’ll own some of the most critical systems in our stack: identity and access, funds movement and ledgering, and the blockchain infrastructure that powers our on-chain trading. This role is similar to staff engineers at leading crypto wallets and exchanges who own authentication stacks, key management, and high-scale financial backends. You’ll design, build, and operate systems that must be both highly reliable and extremely secure, enabling product teams to move quickly on a solid foundation.
