Job summary

US Tech Solutions is seeking an experienced Enterprise COBOL developer to design, code, and test a new account processing function on a z/OS mainframe for a 6-month project in Columbia, SC.

You will analyze the current account master, posting, and balance-maintenance programs, implement end-to-end changes, update batch and month-end cycles, and produce comprehensive test packs while coordinating with accounting stakeholders and ensuring auditability.

Qualifications

• 5+ years of Enterprise COBOL development 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

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.
