  • 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.

  • 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.
