Job Summary:

The ITS Application Developer role focuses on designing, developing, testing, and supporting enhancements to mainframe applications for the State of North Dakota. This mid-to-senior level position requires hands-on expertise in COBOL, Natural, JCL, and database technologies such as ADABAS and DB2. The developer will translate business requirements into technical solutions, collaborate within Agile teams, document processes clearly, and participate in a shared on-call rotation. This is a full-time, remote position with a 12-month duration.

Responsibilities:

  • Analyze requirements and produce technical designs for moderate to complex mainframe application changes.

  • Build and execute test scenarios, perform unit, system, and acceptance testing, and document results.
  • Participate in peer code reviews and incorporate feedback to improve code quality.
  • Maintain runbooks, deployment notes, and other solution documentation.
  • Provide production support as part of a 24 7 rotational on-call schedule, including root-cause analysis and fixes.
  • Estimate time and effort for assigned tasks and assist with project estimates.
  • Engage actively in Agile ceremonies such as stand-ups, planning, reviews, and retrospectives.
  • Document work in team tools and mentor peers informally on standards and procedures.

Required Skills & Certifications:

  • Proficient in COBOL for maintenance and new development.
  • Proficient in Natural programming language.
  • Strong working knowledge of JCL for batch job authoring and troubleshooting.
  • Experience with ADABAS and DB2 databases, including queries and performance basics.
  • Familiarity with Oracle concepts and SQL tools such as PL/SQL Developer.
  • Experience with tools like QMF and Visio or equivalents.
  • Strong technical writing skills for documentation and communication.
  • Minimum of 5 years mainframe development experience in enterprise environments.

Preferred Skills & Certifications:

  • Experience with Natural/ADABAS in public sector or large enterprises.
  • Exposure to mainframe CI/CD and change management tools such as Endevor, ChangeMan, or ISPW.
  • Familiarity with job scheduling platforms like Control M, CA 7, or TWS.
  • Integration experience with MQ, file-based interfaces, or service layers.
  • Prior participation in rotational on-call support.
  • Informal mentorship or focal-point experience.
  • Experience in state government or regulated industries.
  • Bachelor's degree in Computer Science, Information Systems, or related field.

Special Considerations:

  • Participation in a shared 24 7 on-call rotational support model is mandatory.
  • Equipment and software will be provided and shipped by the state's IT division.
  • Virtual interview process requires camera on and recent photo submission.

Scheduling:

  • Full-time position, 40 hours per week.
  • 100% remote work environment.
  • Duration of 12 months with potential for extension.
