• Cross-Platform Flexibility: Some familiarity with PowerShell (or a willingness to learn it!). Since our computing platform integrates both Linux and Windows ecosystems, being able to speak a little "Windows" is an advantage.
• Professional Certifications: RHCSA, RHCE, or CCNA.

In return for your expertise, we’ll support you in this new challenge with coaching & development every step of the way.
