Résumé du poste

HTC Global Services is seeking a Senior Mainframe COBOL/Natural Developer to enhance a mission-critical accounting platform on z/OS. You will extend Enterprise COBOL and Natural applications, implement financial accounting functionality, and ensure accurate processing, reconciliation, and reporting.

The role requires navigating legacy systems, tracing undocumented logic, and delivering reliable enhancements without impacting production. Remote work-from-home is supported with full-time hours.

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 tracing undocumented logic through copybooks, call chains, and job streams.

Responsabilités

• Analyze existing account master, posting, and balance-maintenance programs to identify where new account functionality must be incorporated and document findings.
• Design and develop new account functionality, including master file and table structures, account opening and closing, participant linkage, sweep and reverse-sweep logic, allocation, interest apportionment, and closing balance derivation.
• Modify batch COBOL programs and JCL and extend nightly and month-end processing cycles while maintaining agreed batch-window limits.
• Enhance audit trails, exception reporting, and reconciliation controls in coordination with accounting stakeholders.
• Develop test data, unit and regression test packs, and parallel-run comparisons against current production output.
• Investigate and explain differences identified during testing.
• Support implementation, conversion of in-scope existing accounts, and early-life production runs, including on-call support during initial cycles.
• Prepare program documentation, data-flow notes, and runbook updates for ongoing production support.
