Job description

CCS Global Tech is a rapidly growing Information Technology company with a diverse portfolio of technology products and services and a large network of industry partnerships. With over 22 years of being a successful business with a global talent pool and presence, CCS is a certified Microsoft Gold Partner and specializes in delivering expert Microsoft based solutions for technical and business needs. We have been recognized by Inc. 500 Magazine as one of the fastest growing small companies in the Unites States.
we are a Tier 1 vendor for the City and County of San Francisco for Cloud Services, Staffing Services and Training Services. For this multi-year opportunity with a diverse set of needs to address, we are currently focusing on establishing partnerships with individuals as well as companies who can help us enhance our overall service portfolio, cut lead times, and ultimately help us deliver successfully. We currently hold sizable Government accounts in the San Francisco bay area including City and County of San Francisco, San Mateo County, and Santa Clara County.
We take great pride in our global reach and local influence. Your experience alongside our highly skilled and talented internal team who guide you along the way, offers key insights into what helps you stand out in a competitive job market.
If you are a partner company, please submit resumes with contact information of your own W2 Consultants only. Submitted consultants are expected to have excellent communication skills.

Roles/Responsibility

  • 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.

Mandatory Skills:

  1. 5+ years of Enterprise COBOL development experience in a z/OS environment
  2. 5+ Years of Experience with NaturalOne
  3. 3+ years of JCL development and production support experience
  4. 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
  5. 3+ years of experience working with Adabas and VSAM
  6. 3+ years of experience with tracing undocumented logic through copybooks, call chains, and job streams
  7. 5+ years 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.
  8. 5+ years Natural One - the Eclipse-based Software AG development environment; developing, debugging, and deploying Natural applications from it, including local development and remote z/OS projects.
  9. Natural and Adabas - Natural programs, subprograms, and maps; DDMs, descriptors and super descriptors, and Adabas file design and performance behaviour.
  10. z/OS and JCL - writing and debugging JCL, procs, GDGs, utilities, SORT, and restart/rerun handling; fluent in TSO/ISPF.
  11. Mainframe data stores - VSAM file design and access, and Adabas for z/OS.
  12. Financial accounting logic - double-entry posting, balance and accrual maintenance, value dating, reconciliation, and month-end close in a regulated environment.
  13. 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.

Desirable Skills:

  1. Experience with cash management, account pooling, sweeps, or treasury applications
  2. Experience with CA-7 scheduling and batch operations
  3. Experience with REXX, Python, or Java
  4. Track record of taking a specification from analysis through production implementation with limited supervision.
  5. Clear written communication: you can explain a change to an auditor, a business analyst, and another developer, and adjust the explanation for each.
  6. Degree in computer science or a related field, or equivalent practical experience.

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.
