Remote Mainframe & COBOL Engineer (6mo, ext possible)

Datasoft Technologies, Inc.; Columbia (SC); À distance; USD 90 000 - 152 000; Plein temps

Résumé du poste

Datasoft Technologies, Inc. is seeking an experienced Enterprise COBOL developer to join a remote, 6-month project on a legacy z/OS accounting platform.

You will design and implement a new pooled-account structure, modify COBOL batch programs, extend JCL and batch cycles, and ensure accuracy and traceability of every cent, working with accounting stakeholders and providing thorough documentation.

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.
• COBOL — substantial production experience in Enterprise COBOL on z/OS, both batch and online; comfortable extending large existing programs and reading code you did not write.
• NaturalOne — the Eclipse-based Software AG development environment; developing, debugging, and deploying Natural applications from it, including local development and remote z/OS projects.
• Natural and Adabas — Natural programs, subprograms, and maps; DDMs, descriptors and superdescriptors, and Adabas file design and performance behavior.
• z/OS and JCL — writing and debugging JCL, procs, GDGs, utilities, SORT, and restart/rerun handling; fluent in TSO/ISPF.
• Mainframe data stores — VSAM file design and access, and Adabas for z/OS.
• Financial accounting logic — double-entry posting, balance and accrual maintenance, value dating, reconciliation, and month-end close in a regulated environment.
• Analysis of legacy systems — tracing undocumented logic through copybooks, call chains, and job streams, and stating clearly what a change will and will not affect.

Responsabilités

• 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.
