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 a􀆯ect. 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.
