Description For Backend Engineer, Fintech

One is revolutionizing the financial services landscape with a mission to help customers achieve financial progress. As a Backend Engineer in our Fintech team, you'll be part of a company backed by Ribbit and Walmart, combining the agility of a startup with the impact of major industry players.

The role involves building critical financial infrastructure using modern technologies like TypeScript, Node.js, and Kubernetes. You'll be working on systems that handle sensitive financial data and large-scale money movement, requiring both technical expertise and a deep understanding of banking systems.

We're looking for engineers with 3-7 years of experience who bring a strong background in banking or fintech, along with expertise in event-driven architecture and microservices. The ideal candidate will have a Bachelor's degree (preferably in Computer Science) and experience building customer-facing products.

What makes this opportunity unique is the chance to work on meaningful financial problems affecting millions of Americans. With roughly 25% of U.S. adults being unbanked or underbanked, your work will directly impact financial inclusion. We offer a competitive salary range of $130,000-$170,000, along with comprehensive benefits including equity, 401(k) with match, and flexible work arrangements.

Our culture emphasizes the "Triple H Factor" - Hungry, Humble, Honest. We're remote-friendly while maintaining workspaces in New York, offering the flexibility to choose your work style. You'll be joining at an exciting time, with the opportunity to shape core financial products while working alongside world-class talent.

The engineering team values quality across code, communication, and culture. While experience with our specific stack (fp-ts library, Node/TypeScript, Kubernetes, AWS) is not required, familiarity with functional programming concepts will help you ramp up quickly. You'll be part of a collaborative environment where documentation and clear communication are key to our success as a remote-first organization.
