The ideal candidate will have strong experience with Java Spring, microservices architecture and event‑driven systems using Kafka. You will demonstrate the ability to build robust, scalable and highly available solutions, with hands‑on experience across Docker, Kubernetes, MongoDB and modern observability tooling.
