Overview We are seeking a Production Support Java Software Developer to join a dedicated application support team responsible for maintaining the reliability, performance, and efficiency of core business operations.

• Production Support & Incident Management: Investigate and resolve production issues, perform root cause analysis (RCA), and implement permanent fixes.
• Back-End Services & Database Operations: Tune SQL queries, troubleshoot APIs, optimize performance, and maintain data integrity.
• Monitoring & Performance: Monitor application health, analyze logs, identify performance bottlenecks, and proactively address system vulnerabilities.
• Code Fixes & Enhancements: Develop and deploy bug fixes, minor enhancements, and security patches for Java-based applications.
• Front-End & Workflow Logic: Update controller logic, modify UI views, and maintain core application workflows.
• Testing & Quality Assurance: Write and maintain unit, integration, and regression tests (using BDD/TDD methodologies) to ensure stability.
• Release & Deployment: Assist with production deployments, validate releases, and support rollback activities when necessary.
• Cross-Functional Collaboration: Partner with developers, QA, DevOps engineers, DBAs, and business stakeholders to drive system reliability.
• Documentation: Maintain clear technical runbooks, support procedures, and knowledge base articles.
