• Cost & Performance Optimization: Audit resource usage to right-size environments and reduce unnecessary cloud spend.

What We’re Looking For

We value people who take ownership, think critically, and enjoy working as part of a collaborative team tackling complex challenges. You don’t need to tick every box, but we’re particularly interested in people with skills/experience in:

• Experience: 3+ years in IT infrastructure, cloud administration, or DevOps roles.
• Technical Skills: Strong proficiency in PowerShell, Python, or Azure CLI, plus networking knowledge (VPN gateways, subnets, DNS).
