About OnePay

OnePay is the consumer fintech trusted by millions of Americans to make money better.

Our financial system is broken. High fees, low rates, and too few ways to actually grow your money. We’re fixing it. And we’re moving fast.

We’re an all-in-one financial services platform that brings together banking, high-yield savings, credit cards, point-of-sale lending, investing, and crypto in one place. We also partner with employers, HCM providers, gig platforms, and others to deliver embedded financial services to millions of employees and frontline workers.

We’re backed by Walmart, the world’s largest retailer, and Ribbit Capital, one of fintech’s most respected investors, giving us rare scale, distribution, and the opportunity to build something truly category-defining.

But what really sets OnePay apart is how we move. Our customers don’t have time to wait… and neither do we. This place moves fast, and we’re looking for people who are:

• Ready to run

• Hungry and driven by urgency

• Exceptional at what they do, with low ego

• Comfortable operating in motion

The Role

As a Software Engineer on the Cash Advance team, your work will directly impact how people access, move, and manage their money through innovative cash advance solutions. You will:

• Design and deliver new features that scale with our growing customer base and help ensure a seamless mobile experience for cash advances.

• Collaborate closely with other engineers to ship high-quality code. We enjoy partnering on tough problems unique to cash advance products.

• Create and maintain clear documentation — a must-have for a growing, remote organization.

• Tackle complex challenges at scale, including sensitive financial data, real-time advances, and compliance requirements.

You Bring

• 4+ years of professional experience shipping and scaling user-facing applications or backend services.

• Experience working on mobile or user-facing applications — ideally with React Native or similar frameworks.

• Passion for your craft and care for the people you work with — you value quality across code, communication, and culture.

• Drive and proactivity - everyone here is a builder and executor.

Tools We Use

We use Node and TypeScript on the server, leveraging the NestJS framework within a microservice-oriented architecture running on Kubernetes and AWS. On the client side, we build and ship product features for iOS, Android, and web platforms using React Native. We also embrace AI-assisted development, so engineers have their choice of Claude Code or Cursor to fit their workflow. While you don't need experience with our exact stack, familiarity with modern software engineering practices will help you ramp up quickly.
