  • Work within Azure or AWS using standardised cloud platforms
  • Apply best practices for secrets management, configuration, and secure service‑to‑service communication
  • Monitor systems using cloud‑native and platform monitoring tools
ESSENTIAL SKILLS
  • Kafka streaming technologies (real production experience matters)
  • Java backend engineering, ideally with Quarkus or similar modern frameworks
  • Distributed systems and microservice architectures
  • Cloud platforms (Azure or AWS) and Kubernetes runtimes
  • API design, system integration, and performance optimisation
ADVANTAGEOUS SKILLS
  • Understand security concepts in distributed systems
  • Have solid SQL and data‑mapping experience
