Oneapp QE Platform Engineer at Oneapp to design and own test automation frameworks and infrastructure across web, mobile, and backend services. Improve test coverage and embed quality practices into development workflows.
Responsibilities
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. You will:
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
Qualification
Proficiency in TypeScript/Node
Required
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
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.
