This role is central to delivering the reliability, flexibility, and performance our users will rely on in fast-moving financial markets.

We are a remote-first team and are open to hiring exceptional candidates globally.

Ideal Candidate

You’re a design-minded full stack engineer who builds fast, clean, and modular frontend systems. You thrive on making complex interfaces intuitive—turning strategy logic into drag-and-drop workflows—and can ship high-performance components that integrate seamlessly with real-time APIs. You value design systems, scalable frontends, and cross-functional collaboration.

What We Offer

·      Opportunity to shape the product interface of a next-gen fintech startup.

·      A collaborative, technically driven culture.
