W2/1099 Candidates only: MF Developer (Z/OS/Cobol/NaturalOne/Adabas/JCL/VSAM/Fin Acctg Logic/CA-7): 6+ Mnths 100% Remote Project: $ 102/hr on 1099: $ 95/hr W2

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
• 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.

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.
