• Develop enterprise-grade backend services using Java, Spring Boot, and JPA/Hibernate, and deliver secure RESTful APIs for integration with Billing, Provisioning, Digital, and external systems.
• Write and optimize complex SQL, PL/SQL, and PL/pgSQL queries to support high-volume and performance-critical processing, ensuring data integrity and transaction consistency.
• Work with enterprise data and messaging platforms including PostgreSQL, Oracle, Elasticsearch, Redis, and Kafka.
• Operate within a DevOps “build and run” model, supporting CI/CD pipelines, automated deployments, production releases, and structured on‑call rotations, managing incidents through PagerDuty and ServiceNow.
• Drive platform stability and reliability through end‑to‑end observability (Splunk, Prometheus, Grafana, CloudWatch), proactive monitoring, root cause analysis, SLA adherence, and disaster recovery readiness.
• Collaborate with cross‑functional teams and produce clear technical designs, integration documentation, and operational runbooks.

• 4+ years of combined experience in CRM OM backend development, DevOps, SRE, or Software Engineering.
• Strong hands‑on experience with Java, Spring Boot, and REST API development.
• Solid expertise in PostgreSQL and/or Oracle, including advanced SQL and performance tuning.
• Experience working in Agile/Scrum delivery environments with strong analytical, communication and problem‑solving skills.
• Experience with Docker, Kubernetes, AWS (EKS, EC2, RDS, IAM), and CI/CD pipelines (Jenkins/GitLab).
• Familiarity with Terraform or CloudFormation and scripting (Shell/Python) for automation.
