СOBOL​/Maiframe Engineer IRC

The engagement supports a maintenance assessment and advisory for a legacy mainframe environment built primarily on COBOL, running mission-critical batch and online workloads. The objective is to establish a fact-based understanding of the current application estate and its support model, and to define a scoped, low risk maintenance pilot as the basis for a potential longer term managed services engagement.

The initial advisory phase is an assessment structured in three stages: a scope-alignment workshop to agree services, ownership, and boundaries; a current-state assessment of the code estate, data, batch/online flows, operations, and ticket history to establish baselines and pain points; and a pilot-identification stage to prioritize candidate use cases and define objectives and success metrics. The phase is diagnostic in nature — it covers evaluation, characterization, and effort estimation only, with no code remediation or production changes performed during assessment.

Success depends heavily on timely access to client subject-matter experts and to the target environment.

• 4+ years of hands‑on COBOL maintenance and support experience in a z/OS environment.
• Able to read, trace, and document unfamiliar legacy COBOL, JCL, and batch flows without complete documentation.
• Experience extracting inventories and running static or dependency analysis across a codebase.
• Comfortable working under an architect’s direction and producing structured, reusable analysis artifacts.
• Detail‑oriented and able to work to a tight assessment timeline.

• Extract and catalogue the application, program, copybook, JCL, and data inventory.
• Perform and validate static and dependency analysis and generate code metrics across the estate.
• Trace and document batch and online program flows and their data touchpoints.
• Review AI‑generated inventories and dependency maps and correct errors against source.
• Flag anomalies, dead code, and high‑risk or high‑complexity areas.
• Support the architect in validating findings against client SME input.
