About the role
Description
About Xe
Xe is a cross-border payments platform. We help SMEs and consumers in the US, UK, Canada, Australia, and New Zealand collect, convert, hold, and send money across markets. Each year, over 300 million people use Xe for currency information and over 350,000 use us to send money overseas.
Today, we're rebuilding the platform layer behind cross-border payments for corporate and consumer clients. We're small enough that your code ships fast and your decisions matter, and Euronet Worldwide (Nasdaq: EEFT) backs us so the problems stay real-scale.
About This Role
We're hiring a senior full-stack engineer who owns real problems end-to-end and shapes how the team builds, from API design and frontend experience through to backend services, production reliability, and launch. You already use AI as part of how you think, build, test, and ship.
You'll write code that moves money in production, design and modernize the platform across the stack, and lead delivery of customer-facing features as Xe rebuilds its platform layer. You'll work in a small engineering team with direct access to product, design, and compliance, own architecture in your domain, lead design reviews, mentor mid-level engineers, and partner with architects and team leads on cross-domain decisions.
