- Provide expert guidance on legacy system architecture, integrations, and dependencies.
- Collaborate with project coordinators and technical experts through clear written and verbal communication.
- Ensure all submitted technical materials meet high standards of accuracy, consistency, and completeness.
- Support projects involving legacy-system modernization, migration, integration, or transformation where applicable.
- Proven professional experience as a COBOL Developer or Mainframe Developer.
- Strong proficiency in COBOL programming and legacy application environments.
- Experience working with mainframe systems and related technologies.
- Strong understanding of complex legacy codebases, business rules, and system workflows.
- Excellent analytical and problem-solving skills.
- Ability to explain complex technical concepts clearly and accurately.
- Strong technical writing and documentation skills.
- Exceptional attention to detail.
- Ability to work independently and manage multiple deliverables in a remote environment.
- Experience with large-scale mainframe migration, modernization, or integration projects.
- Familiarity with JCL, DB2, CICS, VSAM , or other common mainframe technologies.
- Experience reviewing or documenting legacy enterprise applications.
- Experience creating technical test scenarios or validating business logic.
