Job summary

CAI is seeking a Cobol Developer to build a new pooled-account structure inside a running z/OS core, without disturbing balances. This remote, contract role requires deep COBOL and JCL expertise to modify batch processes and extend month-end cycles.

You will document findings, add audit and reconciliation controls, create test data, and support implementation and early-life production runs, including on-call coverage.

Qualifications

• 5+ years of Enterprise COBOL development experience in a z/OS environment (batch & online).
• 5+ Years of Experience with NaturalOne; developing, debugging, and deploying
• Experience with Natural programs, subprograms, and maps
• 3+ years of JCL development and production support experience
• 3+ years of experience with financial/accounting systems development or support including double-entry posting, balance/accrual maintenance, value dating, reconciliation, and month-end closeouts in a regulated environment
• 3+ years of experience working with VSAM and Adabas including file design and performance behavior
• 3+ years of experience with tracing undocumented logic through copybooks, call chains, and job streams

Responsibilities

• Analyze the current account master, posting, and balance-maintenance programs to establish where composite reservoir accounts must be recognized, and document what you find
• Design and code the new account type end to end: master file and table structures, account opening and closing, participant linkage, sweep and reverse-sweep logic, allocation and interest apportionment, and closing balance derivation
• Modify batch COBOL programs and JCL and extend the nightly and month-end cycles to include the new processing without lengthening the batch window beyond agreed limits
• Add new CRAs to the audit trail, exception reporting, and reconciliation controls the new function requires, working with accounting stakeholders on what must be evidenced
• Produce test data, unit and regression test packs, and parallel-run comparisons against current production output; investigate every difference until it is explained
• Support implementation, conversion of any in-scope existing accounts, and early-life production runs, including on-call cover during the first cycles
• Leave behind program documentation, data-flow notes, and runbook updates that the support team can work from
