Résumé du poste

Innosoft Corporation seeks an experienced Enterprise COBOL developer for a 6-month remote contract to extend a z/OS mainframe accounting platform. You will read a large COBOL body, implement a pooled-account structure, and ensure postings, balances, and reconciliations are exact.

Responsibilities include modifying COBOL/JCL, extending batch cycles, adding audit trails, producing test data, and supporting conversion and early-life production runs with strong documentation and communication.

Qualifications

• Education: Degree in computer science or related field, or equivalent practical experience.
• Required Skills: 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 with Adabas and VSAM
• 3+ years tracing undocumented logic through copybooks, call chains, and job streams
• Preferred Skills: Experience with cash management, account pooling, sweeps, or treasury applications
• Experience with CA-7 scheduling and batch operations
• Experience with REXX, Python, or Java
• Mixed-estate integration — COBOL and Natural, z/OS Connect, IBM MQ, or REST services
• Scheduling and operations — CA-7 batch window analysis and performance tuning
• Scripting and adjacent languages — REXX or CLIST, plus Java or Python for data migration
• Cash management domain — pooling, sweeps, intercompany allocation
• Additional Skills: Track record of taking a spec from analysis through production with limited supervision
• Clear written communication: explain changes to auditors, business analysts, and developers

Responsabilités

• Analyze the current account master, posting, and balance-maintenance programs to establish recognition points for composite reservoir accounts and document findings.
• Design and code the new account type end to end: master file and table structures, account opening/closing, participant linkage, sweep logic, allocation, and closing balance derivation.
• Modify batch COBOL programs and JCL and extend nightly and month-end cycles to include new processing without lengthening batch windows.
• Add new CRAs to the audit trail, exception reporting, and reconciliation controls; collaborate with accounting stakeholders.
• Produce test data, unit and regression test packs, and parallel-run comparisons against current production output; investigate differences.
• Support implementation, conversion of in-scope accounts, and early-life production runs, including on-call during first cycles.
• Leave behind program documentation, data-flow notes, and runbook updates for the support team.
