Role
Who you are
- 5+ years of professional experience in test automation, QE engineering, or backend/platform engineering with a strong testing focus
- Deep experience designing and building test automation frameworks and tooling (e.g., Playwright, Selenium, Appium, Cypress) that other engineers build on
- 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
- While you don't need experience with our exact stack, familiarity with modern software engineering practices will help you ramp up quickly
What the job involves
- As a QE Platform Engineer at OnePay, your work will directly shape how confidently every engineering team ships to production — building the test automation infrastructure that catches problems before they reach customers of a financial platform millions of people trust
- Design and own shared test automation frameworks used by engineering teams across web, mobile, and backend services
- Build and maintain test execution infrastructure that runs automated suites reliably at scale, including flaky-test detection and triage tooling
- Partner with engineering teams to raise test coverage and testing maturity, embedding quality practices into the development workflow rather than bolting them on afterward
- Develop tooling for test environment provisioning, test data management, and parallelized test execution to keep feedback loops fast
- Instrument and monitor test infrastructure health (pass rates, run times, flakiness) and drive down friction points that slow teams down
- Contribute to internal documentation and best practices that help other engineers write and maintain effective automated tests
- 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
Application process
- Our process varies by role. Most candidates go through:
- AI-assisted initial screen
- Interview with Talent Partner
- Technical or Hiring Manager Interview
- Team Interview
- Executive Interview
- Offer!
Our take
Traditional banking hasn't worked for millions of Americans who are underserved or priced out of the system. High fees, minimum balance requirements, and tough credit checks create barriers that keep everyday people from building financial stability. Meanwhile, fintech startups are proving there's a huge demand for simpler, more accessible financial services. But most of these apps still focus on just one or two features, forcing users to juggle multiple platforms to manage their money.
OnePay is Walmart's all-in-one financial platform bringing everything together in a single app. Launched in 2021 through a partnership with Ribbit Capital, OnePay expanded after Walmart acquired fintechs Even and ONE in 2022. The platform now includes buy-now-pay-later and, through a new DriveWealth partnership, stock and ETF investing. On top of this, OnePay also serves employers with a B2B financial wellness suite to improve employee stability and engagement.
OnePay is already helping millions of consumers and has earned a 4.8-star app rating. More recently it announced crypto trading for Bitcoin and Ether, and partnerships with Workday Wellness and Klarna, further expanding its offerings. With this momentum, the platform is really positioning itself as a true one-stop financial hub.
