QE Platform Engineer

Full Job Description

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 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

You Bring

• 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

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

Standard Interview 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!
