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 Quality Platform Engineer at OnePay, your work will directly shape how confidently every engineering team ships to production, building the internal tooling that catches problems before they reach customers of a financial platform millions of people trust. You will:
Design and own shared automation frameworks used by engineering teams across web, mobile, and backend services
Build and maintain infrastructure that runs automated suites reliably at scale, including flaky-test detection and triage tooling
Partner with engineering teams to raise coverage and testing maturity, embedding quality practices into the development workflow rather than bolting them on afterward
Develop platform for test environment provisioning, data management, and parallelized execution to keep feedback loops fast
Define quality standards, provide observability (coverage, pass rates, run times), and maintain documentation and best practices to help engineers write and maintain effective automated tests
5+ years of professional experience in frontend/backend/platform engineering with a strong testing focus
Proficiency in TypeScript/Node.js or similar languages, with experience architecting test frameworks rather than just writing test cases
Experience with cloud-native infrastructure (Kubernetes, AWS) and containerized test environments
Familiarity with testing across the stack: API/integration testing, end-to-end testing for web and mobile (e.g., React Native)
Strong communication and collaboration skills, able to influence testing practices across multiple engineering teams
Drive and proactivity - everyone here is a builder and executor
We use Typescript front to back, with node and NestJS frameworks for server code and React Native for our iOS, Android, and Web clients. We run on a highly distributed cloud-native stack with Kubernetes and AWS, and scale and resiliency are at the heart of everything we build. We also embrace agentic development, so engineers have their choice of a variety of models and agent harnesses, including Claude Code, Cursor, Codex, and more 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.
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
