Senior Java Software Engineer

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.
