What started as five people, a small office, and a few nerf guns (to stay awake) has now grown into one of Europe’s fastest-growing fintechs. With 100+ colleagues, offices in Delft, Berlin, and London, and Worldline as a partner, we have the perfect mix: the resources of a global player with the energy of a scale-up. At OPP, we build the technology that powers the next generation of e-commerce. From eBay to Ikea, billions in transactions already flow through our systems. We don’t just handle payments—we enable platforms to accept, hold, and disburse funds securely.

As a QA Engineer, you’ll be responsible for ensuring the quality, reliability, and performance of our customer-facing web applications and APIs. You will:

• Design, implement, and execute comprehensive test plans for web applications, including KYC
• Automate back-end (API) front-end testing, and end-to-end workflows using tools of choice.
• Perform functional, integration, and regression testing on Laravel-based back-ends and React.js front-ends.
• Validate API functionality, error handling, and performance under various conditions.
• Conduct performance testing to ensure scalability and reliability.
• Ensure cross-browser and device compatibility, including accessibility and usability testing.
• Implement security and accessiblity testing for sensitive customer-facing workflows such as payment flows and onboarding flows.
• Track and document issues, test results, and improvements using Jira.
