Senior Software Engineer (Java) - API Excellence

About the Team: Adyen's Single Platform is a cornerstone of our business, and we empower our teams with autonomy to drive its growth. This dynamic environment has led to a rich and evolving API ecosystem. To build on this success, we are continually investing in the developer experience, enhancing the consistency and ease of use across all our APIs and SDKs. This ongoing commitment makes integration faster for our customers and accelerates our own pace of delivering new features. The API Excellence team is being formed at a critical juncture, with the rise of AI-assisted development, to address these challenges and create a single platform API experience that empowers developers—both human and AI—to build with speed and confidence. This team is central to that vision. The Scope: You will oversee the architecture not just for our core APIs, but also for our client-facing SDKs across Java, C#, Node.js, Go, Ruby, Python, and PHP. The Mission: We are defining the 'Golden Path' for API development, building the tooling that empowers developers—both human and AI—to build with speed and confidence.
