Java Engineer (Java Application Core Components Team)

• Adyen provides a global, unified platform built by Java application teams across the company
• The Java Application Core Components (JACC) team plays a key role in this: we build and maintain the shared frameworks and components that define how other Adyen teams design, structure, and deploy their Java applications
• As part of JACC, you will build and maintain the core Java tools and components used across all of Adyen, shaping how other engineering teams build their services
• You’ll work on some of the largest ongoing efforts in the company, including 3 large-scale migrations that will shape the future of Adyen’s application architecture
• You’ll join a lean team of 6 Java experts, working in a Kanban-like way with minimal process overhead, and gain real influence over the architecture of one of the leading players in the payments space
• Design, build, and evolve the internal and open source Java frameworks and components used by every Java application team at Adyen
• Play an active role in one or more of the team’s 3 large-scale migrations that are reshaping Adyen’s application architecture
• Provide hands-on technical guidance to other engineering teams, by guiding them on how the frameworks and libraries we provide can be used to solve Adyen’s business problems
• Design and evolve workflows used by other engineering teams across Adyen, working closely with them to identify pain points and improvement opportunities
• Collaborate with partner platform teams (Kubernetes infrastructure, deployment, security) to make sure our components integrate well across Adyen’s tech stack
• Advocate for best practices across Adyen and define boundaries/guidance on how the frameworks/libraries we maintain can be used. This should be achieved by creating code validation rules, running workshops and giving presentations to other development teams
