Principal Engineer

About the Company

We are building the Everything Store for Finance. We have combined three powerful financial primitives: Exchange, Asset Management, and Borrow/Lend, all seamlessly composable and accessible through one unified account that uses your entire portfolio as collateral, including spot and derivative assets. Trade 250+ markets on a super exchange with zero fees, better-than-CEX liquidity, and institutional-grade privacy, all built on a blazingly fast blockchain. Backed by top-tier investors, we are scaling fast and building a team of mission-driven engineers to redefine what is possible in decentralised finance. There are no product managers, no managers, no 1:1s. Just code. You will work directly with our CEO and a small, elite team of builders every day, pushing the limits of performance and U

X.
