• Ensure software quality through automated testing using JUnit, Mockito, Selenium, Cucumber, and Postman.
• Support observability, troubleshooting, and performance tuning using structured logging, monitoring, and debugging tools.
• Participate in code reviews, sprint planning, backlog refinement, and technical documentation.
• Mentor junior developers and contribute to engineering best practices, architecture standards, and reusable frameworks.

Required Qualifications

• Bachelor's degree in Computer Science, Engineering, or related field.
• 10+ years of experience in backend or full stack enterprise application development with strong backend focus.
• Deep expertise in Core Java and J2EE including Servlets, JDBC, JPA, Hibernate, and Spring Framework.
• Strong experience with Spring Boot, microservices architecture, and distributed systems design.
• Proven experience building REST APIs, GraphQL APIs, and backend integration services.
• Strong experience with relational and non-relational databases.
• Hands-on experience with messaging, streaming, and event-driven systems.
• Strong understanding of cloud-native development across AWS, Azure, and/or GCP.
• Experience with Docker, Kubernetes, Helm, and infrastructure automation tools such as Terraform, CloudFormation, or Ansible.
• Proficiency with Git-based version control, branching strategies, pull requests, and collaborative development workflows.
• Experience working in Agile/Scrum environments using JIRA, Rally, and Confluence.
• Strong problem-solving, analytical, and communication skills.
• Proven ability to troubleshoot and optimize high-volume, distributed enterprise systems.

Preferred Qualifications

• Experience in financial services, banking, payments, fraud risk analytics, telecom, or property management.
• Exposure to frontend frameworks such as Angular or React for effective collaboration across full stack teams.
• Experience integrating backend platforms with analytics and reporting systems.
• Familiarity with server-side rendering, lazy loading, and performance optimization techniques in full stack environments.
• Experience using AI-assisted development tools such as GitHub Copilot or IntelliJ Copilot to accelerate engineering productivity.
