Job Description

We are looking for a Senior Software Developer (COBOL / Java) to support a system modernization initiative, contributing to the migration of legacy COBOL applications toward a Java-based architecture. The role combines hands-on Java development with legacy COBOL analysis, technical solution design, testing, and migration delivery to ensure business logic continuity throughout the transition.

Key Responsibilities

Participate in client workshops to capture requirements, understand existing COBOL system behavior, and translate them into target technical solutions.
Prepare Product Design Documents and Technical Specifications for Java development, system integration, migration work packages, and change requests.
Support Business Analysts with technical analysis, solution proposals, impact assessments, and development estimations.
Analyze and reverse-engineer legacy COBOL applications and business logic to support migration toward the target Java architecture.
Design and develop medium-to-complex Java applications using Java EE / Spring technologies.
Perform impact analysis, technical estimation, and risk assessment for functional stories, migration activities, and change requests.
Support migration risk assessment and mitigation, including data integrity, parallel runs, system compatibility, and cutover.
Perform Unit, Integration, and System Testing, including validation of Java applications against existing COBOL system behavior.
Provide technical guidance to offshore and distributed development teams.
Support clients during UAT, including technical enquiries, batch job execution in simulation environments, and issue resolution.
Collaborate with Project Managers, Project Leads, Business Analysts, developers, testers, and production support teams throughout project delivery.
Maintain technical and domain-level artifacts in line with established project methodology.
