Description For Backend Engineer, Fintech

One is an innovative fintech company on a mission to revolutionize how customers achieve financial progress. Backed by prominent investors Ribbit and Walmart, we're creating an all-in-one platform for saving, spending, borrowing, and growing money. We're addressing a critical gap in the U.S. financial landscape, where millions of Americans struggle with access to credit and efficient money management.

As a Backend Engineer in our Fintech team, you'll be at the forefront of building the systems that power our financial products. You'll work with modern technologies like TypeScript, Node.js, and Kubernetes on AWS, utilizing functional programming principles through the fp-ts library. Your role will involve architecting and implementing software applications, developing new features from scratch, and handling complex challenges around large-scale money movement and sensitive financial data.

The ideal candidate brings 3-7 years of experience, preferably with a background in computer science and fintech/banking systems. You should be comfortable with event-driven architecture, microservices, and have a solid understanding of banking protocols and security standards. We value engineers who can work independently, demonstrate technical excellence, and contribute to our collaborative, remote-first culture.

We offer a competitive compensation package ranging from $130,000 to $170,000, along with comprehensive benefits including stock options, flexible time off, 401(k) with match, and parental leave. Join us in our mission to transform financial services while working with a world-class team in a fast-paced, growth-oriented environment.
