This role requires close collaboration with cross‑functional teams, adherence to DevOps and Agile practices, and ownership of service quality and delivery.

Key Responsibilities

• Microservices Development: Design, develop, and maintain high-throughput backend services and RESTful / event-driven APIs (Kafka) using Java 17+ and Spring Boot.
• Cloud-Native Deployment: Deploy and manage applications in Kubernetes (K8s) environments, ensuring scalability and high availability.
• Caching & Optimization: Implement caching strategies using Redis or Memcached to minimize database load and optimize performance.
• Event-Driven Systems: Work with messaging systems (e.g., Kafka) to create asynchronous, event-driven architectures.
• Database Management: Maintain database schemas and write optimized queries for SQL (PostgreSQL, MySQL) and NoSQL (Cassandra, MongoDB) databases.
• CI/CD & DevOps: Collaborate on CI/CD pipelines (ArgoCD, Jenkins, Artifactory, DevSecOps) and monitor services using observability tools
