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. /ppAt 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 senior engineer, you’ll join one of our four tech teams, working on the architecture of our platform: a scalable backend that processes big data for more than 10 million users. We’re disruptive: we build everything ourselves, from the ground up. You’ll combine strategic thinking with hands-on implementation, knowledge-sharing, and creative programming. As a team, we strive for scalable code with long-term maintainability, Fort Knox-level security, and replacing legacy systems with microservices. /ppbProjects on our roadmap: /b /pullibIn-person payments (POS): /b Currently, OPP only offers online e-commerce payments.
