ADABAS Mainframe App Dev.

Position Summary

The Mainframe Developer will design, develop, test, and support enhancements to existing mainframe applications used across State of North Dakota programs. The role is primarily hands-on development with COBOL, Natural, JCL, and databases such as ADABAS and DB2 (Oracle familiarity is a plus). The ideal candidate translates business requirements into practical technical solutions, produces clear documentation, collaborates in Agile teams, and participates in a shared on-call rotation.

Key Responsibilities

Technical Analysis & Design (mid-to-senior scope)

• Analyze requirements and produce practical technical designs for moderate to complex changes within established patterns/standards.
• Create and update design documentation (program specs, data mappings, flow diagrams) and walk through with stakeholders for approval.
• Recommend incremental improvements that align with existing architecture (no enterprise architecture ownership).

Coding & Configuration

• Develop and maintain programs using COBOL and/or Natural.
• Author and troubleshoot JCL for batch processes, job streams, and error handling.
• Build test scenarios and perform unit, system, and acceptance testing; document results.
• Participate in peer code reviews and apply feedback to improve quality.
• Maintain runbooks, deployment notes, and solution documentation.
• Provide production support in a rotational 24×7 on-call model; perform root-cause analysis and implement fixes.

Project & Team Collaboration

• Provide time and effort estimates for assigned work items and small enhancements; assist on estimates for moderate projects.
• Actively participate in Agile ceremonies (stand-ups, planning, reviews, retros).
• Document tickets, decisions, and work acceptance in team tools.
• Mentor peers informally on standards and procedures as needed (no formal people leadership).
