Software Engineer, Quality Engineering

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 Quality Engineer at OnePay, you'll build the systems that let our product teams ship fast without breaking things. QA teams are often seen as a bottleneck; our goal is to speed things up. This isn't a checkbox quality engineering role - you'll be writing real code, designing agentic testing frameworks, and working at the intersection of quality, feature, and platform engineering. You will:

• Build and maintain automation frameworks that test our mobile app and backend systems at scale.

• Design and develop agentic testing flows and tooling that maintains quality at the pace of development.

• Partner with feature development and platform teams to enable testing + ship with confidence.

YOU BRING

• 3–8 years of professional engineering experience in quality, SDET, or automation work.

• An engineering background specializing in quality, not a testing background in scripts.

• Deep understanding of the systems you're testing and how they actually work under the hood.

• Experience building test frameworks or automation infrastructure from scratch.

• Comfort with AI-native development using tools like Claude or Cursor to compound your output.

• 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.

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
