The Role
As a Quality Engineer at OnePay, you'll build the systems that let our product teams ship fast without breaking things. QA teams are often seen as a bottleneck; our goal is to speed things up. This isn't a checkbox quality engineering role - you'll be writing real code, designing agentic testing frameworks, and working at the intersection of quality, feature, and platform engineering.
You Will:
- Build and maintain automation frameworks that test our mobile app and backend systems at scale.
- Design and develop agentic testing flows and tooling that maintains quality at the pace of development.
- Partner with feature development and platform teams to enable testing + ship with confidence.
You Bring:
- 3–8 years of professional engineering experience in quality, SDET, or automation work.
- An engineering background specializing in quality, not a testing background in scripts.
- Deep understanding of the systems you're testing and how they actually work under the hood.
- Experience building test frameworks or automation infrastructure from scratch.
- Comfort with AI-native development using tools like Claude or Cursor to compound your output.
- 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:
- Initial Interview with Talent Partner
- Technical or Hiring Manager Interview
