Mainframe Automation Manager – 100% Remote

Practical: Start date: ASAP | Duration: 1 year + extension | Hours per week: 40 | Contract type: Deta | Rate: to be discussed / local rates apply.

About the Role: We are seeking a highly skilled Mainframe Automation Manager to lead a critical, large-scale automation migration project. You will be joining the initiative at a pivotal moment: the migration is currently 50% complete, with the remaining 50% left to execute. This project strictly follows an IBM migration approach, transitioning legacy systems to modern IBM tooling.

The Core Technical Challenge: The primary mission of this role is a massive conversion effort. The environment currently holds legacy REXX scripts that must be converted to IBM System Automation.

We are looking for a specialist who is either an absolute expert on both sides (REXX and IBM System Automation) OR a strategic technical leader who possesses the architectural vision and foresight to design a viable conversion framework that makes this massive migration work efficiently.

You will work in a technical Mainframe environment where automation, system stability and availability are important.

1. Location: fully remote.
2. Hours: 40 hours per week.
3. Working hours: 08:30–17:00 CET.
4. Working language: English.
5. Joining preference: immediate availability.
