About OnePay

OnePay is a consumer financial services app with an exceedingly simple mission: to help people achieve financial progress.

Tens of millions of Americans today are unbanked or underbanked, meaning they don’t have enough money in savings to cover a minor emergency. They pay too much in fees, don’t have access to credit at affordable rates, and have little ability to grow their wealth. OnePay’s vision is to create a single app for consumers to save, spend, borrow, and grow their money, bringing our mission to life with simple and accessible banking, credit, and payments products that deliver a best-in-class experience to millions of customers. Our products include:

  • Checking and high-yield savings accounts

  • Domestic and international peer-to-peer payments

  • Credit Builder and credit score monitoring

  • Digital wallet / contactless payment solutions

  • Buy-now-pay-later installment loans at Walmart

Why do we have a right to win? We have the backing of Walmart (a Fortune 1) and Ribbit Capital (a preeminent fintech investor), are deeply embedded with the distribution of the world’s largest omnichannel retailer, and have an industry-leading multi-product value proposition — all in addition to having some of the best people and talent in the industry.

There’s never been a better time to build a category-defining business and there has rarely been a team better positioned for the opportunity. Join us!

The role

Software Engineers at One build the products & systems that serve our customers and run our company. Besides writing, reviewing, and shipping code, engineers collaborate with others across the company, from product, design, and data to, customer support, ops, and compliance. Software Engineers at One are highly technical, communicative, and emotionally intelligent.

This role is responsible for:

  • Working closely with other engineers to ship code. We enjoy collaboration and partnering on hard problems.

  • Building and maintaining documentation. As a growing and remote organization, having the necessary docs are key to our success.

  • Solving complex problems that arise at scale. We deal with real-world money movement, sensitive financial data at scale, and are creating novel financial mechanics with no real precedent.

The Team

The Servicing team builds the systems that power customer support and internal operations at scale. From AI-driven chatbots using LLMs + RAG to tools that help agents resolve issues fast, our work directly impacts how OnePay serves millions of users. We send over 150M+ comms/month (and still growing), automate voice/chat interactions, and support servicing for new products like Invest, Crypto, and Credit. Our team tackles everything from dispute workflows to agent authorization, enabling seamless, secure, and scalable servicing.

If you love solving complex problems, building for scale, and shaping how customers interact with financial services, this is the team for you.
