Job Description

Title: Senior Java Developer Location: Bangalore- hybrid Experience: 7+ Years Key Responsibilities Assess, recode, and upgrade existing Java 8 EJB and JSF components to ensure full compatibility with WAS 9.0.5.25 and RHEL 8.6+ platform standards. Leverage Kiro (AI-assisted IDE) to accelerate application recoding, code generation, and unit test development — delivering modernized solutions efficiently and to bank-defined quality standards. Perform detailed code analysis and impact assessment — identifying compatibility issues, deprecated APIs, and configuration changes required for WAS 9.x migration. Develop and execute comprehensive unit tests for all migrated and recoded components — ensuring functional parity, regression confidence, and code quality across the modernized platform. Configure and validate Java runtime environments — Java 8 SR6+ and Adopt OpenJDK 8u292+ — ensuring correct JVM configuration, performance tuning, and compatibility with WAS 9.x. Work closely with platform, infrastructure, and DevOps teams — ensuring migrated applications are correctly deployed, configured, and validated across Dev, Test, UAT, and Production environments on RHEL 8.6+. Collaborate with architects and senior stakeholders — providing migration progress updates, risk assessments, and technical recommendations throughout the upgrade programme. Produce clear technical documentation — migration runbooks, code change logs, compatibility matrices, and deployment guides aligned to bank standards. Contribute to CI/CD pipeline integration — ensuring migrated components are built, tested, and deployed through automated pipelines consistently across all environments. What We're Looking For 8+ years of hands-on Java development experience with proven expertise in Java 8 — EJB, JSF, and enterprise Java component development in production environments. Strong WebSphere Application Server (WAS) experience — WAS 9.x configuration, deployment, troubleshooting, and migration from earlier WAS versions. Proven application migration and modernization experience — upgrading legacy Java applications to modern platform standards in regulated financial services environments. Experience with RHEL / Linux environments — application deployment, configuration management, and troubleshooting on RHEL 8.6+. Hands-on experience with Kiro or equivalent AI-assisted development tools — leveraging AI coding assistants for accelerated development, recoding, and unit test generation- Prefered Strong unit testing skills — JUnit, Mockito — with a disciplined approach to test coverage and regression validation across migrated components. Proficiency with build tools — Maven / Gradle — and CI/CD pipelines for automated build, test, and deployment of Java enterprise applications. Strong analytical skills — able to assess legacy codebases, identify migration risks, and implement pragmatic, bank-standard compliant solutions. Excellent communication skills — able to engage architects, platform teams, and senior stakeholders with clear migration status updates and technical recommendations. Nice to Have Experience with Adopt OpenJDK / Eclipse Temurin JVM configuration and tuning. Familiarity with containerization — Docker / Kubernetes — for modernized Java application deployment alongside WAS. Exposure to Spring Boot migration alongside WAS modernization. Knowledge of financial services, bank technology standards and delivery governance. Experience with static code analysis tools — SonarQube, Checkstyle — for code quality enforcement during migration. AWS Kiro certification or formal AI-assisted development tool training.
