OnePay is a consumer fintech platform trusted by millions of Americans, offering an all-in-one financial services experience combining banking, high-yield savings, credit cards, point-of-sale lending, investing, and crypto. Backed by Walmart and Ribbit Capital, the company is building a category-defining financial platform with rare scale and distribution.
As a QE Platform Engineer, you will own the test automation infrastructure that enables engineering teams to ship to production with confidence across web, mobile, and backend services. Your responsibilities include:
• 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
• 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
The company operates with a fast-moving culture, using Node and TypeScript on the server with NestJS framework in a microservice-oriented architecture running on Kubernetes and AWS. Client-side development uses React Native for iOS, Android, and web platforms. The team embraces AI-assisted development tools like Claude Code and Cursor.
Requirements:
• 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 — builders and executors preferred
