  • Troubleshoot application, database, batch, and interface issues within NOMAD and MVS environments.
  • Develop and maintain technical documentation, data mappings, and migration artifacts.
  • 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.

Required QualificationsTechnical Skills
  • 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.
  • Extensive Mainframe development experience.
  • Experience working within MVS/zOS environments.
  • Strong understanding of batch processing, JCL, and job scheduling.
  • Experience with data migration and legacy application modernization initiatives.
  • Knowledge of database design, data analysis, and application troubleshooting.
  • Experience supporting large enterprise business applications.
Business & Communication Skills
  • Ability to communicate effectively with both technical and non-technical stakeholders.
  • Experience working directly with business users to gather requirements and resolve issues.
  • Strong analytical and problem-solving skills.
  • Ability to work independently in a small team environment.
  • Experience supporting production-critical systems with high visibility.
Preferred Qualifications
  • Experience supporting Human Resources, Payroll, Benefits, or Timekeeping systems.
  • Experience working within government organizations or large public-sector environments.
  • Knowledge of employee lifecycle processes and workforce management systems.
  • Experience participating in platform migration or data conversion projects.
  • Familiarity with legacy system modernization strategies.
