Company DescriptionWise is a global technology company, building the best way to move and manage the world's money. As part of our team, you will be helping us create an entirely new network for the world's money. We are hiring across two distinct phases of the product lifecycle: scaling a global success and building a new frontier from scratch. The Mission: Our goal is for the Wise Account to become the world's primary financial hub. We've already started by helping customers earn over 50m every month on their balances. Now, we're looking for engineers to help us lead the next evolution of global wealth. We've created a current account experience backed by real assets—government rates and global indices—where customers get daily returns with instant access and zero lock-ins. The Tech: You'll be architecting a high-availability "Yield Engine" that manages billions in assets while maintaining bankruptcy-protected custody and seamless, near-instant liquidity. We are moving beyond index funds to let customers invest in individual stocks and build long-term, tax-beneficial money pots (like ISAs and SIPPs) directly inside Wise. You will define the technical foundations, brokerage infrastructure, and trading interfaces from the ground up. The Tech: You aren't just shipping features; you are shaping the strategy and code for a brand-new pillar of the Wise ecosystem. You'll be building a product you can actually be proud of. Whether you are scaling a global engine or building a stock brokerage, you'll be handling high-concurrency systems where data integrity and consistency are absolute.
