Description

*) 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 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 of experience working with Adabas and VSAM
*) 3+ years of experience with tracing undocumented logic through copybooks, call chains, and job streams
 
These are the skills we expect to see evidence of in the first conversation.
*) 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 super descriptors, 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.
 
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

Not required to apply. Each of these will shorten your ramp-up, and we will support you in learning the ones you do not have.
*) Mixed-estate integration — calling between COBOL and Natural, and exposing mainframe function through 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 for tooling, plus Java or Python for data comparison and migration work.
*) Cash management domain — notional and physical pooling, cash concentration, sweeps, and intercompany allocation.
 
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
