Fin is a next-generation payments platform built for high-value, global, and instant transactions. We are a Series A-stage company backed by Sequoia, Circle, and other notable investors. Powered by stablecoins, Fin enables users and businesses to move millions of dollars in seconds - whether to other Fin users, directly into bank accounts, or across crypto rails. By combining the speed of crypto with the reliability and trust of traditional finance, Fin reimagines how money moves worldwide. If banks and payment products were reinvented today, they would look like Fin. About the Role We are looking for a Mobile Engineer to own our mobile experience across iOS and Android using React Native. This will be the first time many users interact with Fin, so your work will define how our product feels in the real world. You will turn messy real world payment flows into simple, intuitive interfaces, and help hide the complexity of crypto, wallets, and cross border settlement behind a smooth mobile experience. You will work closely with the founders and the rest of the engineering team, make foundational decisions about architecture and design, and ship features from idea to production. If you care about building delightful consumer products on top of serious infrastructure, this is for you. We value your time: our process focuses on practical system design and architectural discussions, not LeetCode grinding or unpaid take-home assignments.
