  • 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.

  • 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.
