Work Location: Fully remote
Duration: 6 months with possibility of extension
Terms: W2 Contract
Candidate Location: Must be comfortable working Eastern Time Zone hours
Responsibilities: - Build a new pooled-account structure inside a running z/OS core, without disturbing the balances already on it.
- 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.
Required Qualifications:- 5+ years of Enterprise COBOL development experience in a z/OS environment.
- 5+ years of experience with NaturalOne.
- 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 Adabas and VSAM.
- 3+ years of experience with tracing undocumented logic through copybooks,
- call chains, and job streams.
Preferred Qualifications:- Experience with cash management, account pooling, sweeps, or treasury applications.
- Experience with CA-7 scheduling and batch operations.
- Experience with REXX, Python, or Java.
Additional Skills:- Track record of taking a specification from analysis through production implementation with limited supervision.
- Clear written communication: you can explain a change to an auditor, a business analyst, and another developer, and adjust the explanation for each.
- Degree in computer science or a related field, or equivalent practical experience.
