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

As a Software Engineer on OnePay’s Servicing Engineering team, you will build and maintain the systems, tools, and workflows that enable our Operations and Customer Servicing teams to support millions of customers, reporting to an Engineering Manager within the Servicing organization.

What You’ll Do

• Architect, design, and implement software applications that power internal servicing tools and customer support workflows

• Ability to work independently with a high bar for execution, including mentoring others and owning problems end to end

On the client side, we build and ship product features for iOS, Android, and web platforms using React Native.
