  • Support system testing, integration testing, user acceptance testing, and production deployments.
  • Participate in code reviews, knowledge transfer activities, and application support rotations.
  • Collaborate with senior developers and cross-functional technical teams to ensure successful project delivery.

The team supports both NOMAD and MVS platforms and works closely with business users across the department.

  • 5+ years of experience developing and supporting NOMAD applications.
  • Strong knowledge of NOMAD database structures, dictionaries, attributes, segments, and reporting capabilities.
  • Experience with NOMAD commands, queries, screens, reports, and application development.

  • Experience working within MVS/zOS environments.
  • Strong understanding of batch processing, JCL, and job scheduling.
