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 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 aect. 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.
