Software Engineer, Servicing
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 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
• Build new features end to end, including early stage 0 to 1 initiatives supporting customer servicing and operations
• Collaborate cross functionally with Operations, Product, and external vendors to deliver integrations and tooling at scale
• Solve complex, real world problems involving large scale money movement and sensitive financial data
• Create and maintain clear technical documentation to support a growing, distributed engineering organization
You Bring
• 3+ years of professional software engineering experience in fintech, banking, or consumer technology
• Experience building, shipping, and scaling customer facing or internal platform products
• Strong understanding of distributed systems, event driven architectures, and microservices
• Familiarity with banking systems, financial transactions, APIs, and security standards
• Ability to work independently with a high bar for execution, including mentoring others and owning problems end to end
• 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. While you don’t need experience with our exact stack, familiarity with modern software engineering practices will help you ramp up quickly.
What We Offer
Competitive base salary, stock options, and health benefits from Day 1
401(k) plan with company match
Remote-friendly (US), flexible time off (FTO), and opportunities for growth
A high-growth, mission-driven, inclusive culture where your work has real impact
