Responsibilities:
- Design, develop, and maintain Java backend services and microservices using Spring Boot and the broader Spring ecosystem (Spring Data, Spring Security, Spring Cloud).
- Build and consume RESTful APIs and event-driven services, applying clean architecture and domain-driven design where appropriate.
- Implement integrations with downstream systems and external partners using REST, messaging (Azure Service Bus, Kafka, or Pub/Sub), and batch interfaces.
- Work with relational and non-relational data stores, writing efficient queries and persistence code with JPA/Hibernate.
- Containerise services using Docker and deploy to Azure Kubernetes Service (AKS).
- Contribute to CI/CD pipelines (Azure DevOps and/or GitHub Actions), with automated build, test, and deployment steps.
- Write comprehensive unit, integration, and contract tests.
- Participate in code reviews, design discussions, and architecture sessions; advocate for clean code, performance, and security best practices.
- Support production services on a shared rotation, contributing to monitoring, alerting, and incident response.
