Senior Fullstack Engineer

About the role

You will design, build, and enhance applications that manage the complete lifecycle of debit and credit card services, covering issuance, blocking, replacement, limit adjustments, and PIN requests. You will contribute to a large-scale migration of millions of legacy cards onto a new platform, consolidating microservices and frontends into a single, reusable, product-agnostic solution intended for reuse across countries and currencies. You will help shape new credit card offerings, including subscription-based models, as part of a broader push to modernize the product portfolio. You will work across the stack - with a focus on backend - using Java, Spring Boot, Maven, Azure DevOps, Kafka, Cassandra, and Oracle, alongside Lit HTML/Web Components and NPM on the frontend. You will take ownership end-to-end: refine, code, test, and deploy your own work to immutable containers running on OpenShift, using Helm, Kubernetes, and Docker (Compose). You will act as a technical lead and mentor, while also learning from colleagues across a diverse, multidisciplinary team. You will share knowledge with the wider engineering organization through documentation, presentations, and workshops, helping shape new standards for how the team works.
