Role Overview

We’re hiring a Systems Administrator Team Lead to lead our Systems Team, responsible for reliable, secure, and scalable operations across IT, cloud/server infrastructure, hosting platforms, and Live Production Support (LPS).

• Oversee hosting platforms (Plesk, WordPress)
• Improve automation, DevOps, and deployment workflows
• Strengthen uptime, monitoring, and disaster recovery

• Balances technical depth with practical decision‑making

What You Bring

• Experience leading a small technical team
