IT Security Engineer

We're partnering with a market leading organisation to find a dynamic Security Engineer to join their close knit security function. This is a hybrid working position, we're looking for someone who thrives in autonomy and enjoys solving problems before they become incidents.

What's different about this role?

This isn't a role where you'll sit back and triage tickets. You'll be working in close knit team, actively involved in developing security strategies, responding to threats and strengthening infrastructure. You'll also occasionally lend a hand across IT when needed - so a generalist IT background is helpful too.
The environment is Microsoft-focused (Azure, M365, Defender), with Exabeam as the primary SIEM, and you'll play a key part in their journey toward Cyber Essentials Plus certification.
