About the role
Application
This company is building the best way to trade crypto on your phone. What Robinhood did to stock trading a decade ago, they are doing to crypto trading today.
Three mega trends are converging to create a unique opportunity to build the greatest trading product ever created:
Volume moving from centralized exchanges to decentralized exchanges/self custodial solutions
Crypto traders moving from trading on desktop to mobile
The tokenization of everything, including stocks and commodities
Imagine trading literally anything from one app on your phone, instantly, with great execution, from anywhere in the world.
About this role
We are looking for a Founding Mobile Engineer with 6+ years of experience to architect and build a high-performance crypto trading app from the ground up. You'll be the first and only front-end engineer, owning everything the user touches, from cold start to trade confirmation, at a self-funded, fast-moving team that scaled their last product to $5.4M revenue in year one with just two people.
What will you be doing?
Architect the entire React Native mobile app from zero, making all foundational technical decisions
Build a best-in-class trading experience (spot + perps) optimized for speed and low latency across all interactions
Ship the app from 0 to App Store on a rapid timeline, working closely with the founder and a dedicated UI/UX designer
Ensure the app scales to handle 25–50K+ daily active users and $100M+ daily volume with no performance degradation
Own production reliability end-to-end, ix critical bugs the hour they land and automate release pipelines
