• Perform IT Service Management functions including creating tickets, communicating directly with users/IT staff, fielding incident escalations, performing troubleshooting operations and thoroughly documenting progress/status.
• ASRS intent is to transition this temp position to full‑time employee after a period of 6‑9 months. Long‑term temporary status is not an option

Key Responsibilities and Qualifications:

• Experience Required: One or more relevant industry‑accepted certifications related to the following technologies: AWS, Cisco, Microsoft, VMWare, etc.

Skills Preferred:

• I added that previous experience with those is desired, but I don't really expect to find anyone with that experience.
• They won't need to use the AZ360 financial system.
