Overview
We're looking for a hands‐on Security SME to step into a key operational role.
This is a technical position for someone who knows how things actually work in production, not just on paper.
You'll be dealing with Windows SOE, Linux systems, security operations, and real network troubleshooting, from basic issues right through to complex incidents.
You'll also work heavily across Microsoft GSA, Azure tenants, and Entra ID in a live setting that supports critical services.
What you'll be doing
* Be the go‐to security and operations SME for Windows, Linux, and cloud platforms.
* Look after platform hardening, patching, standards, and day‐to‐day support.
* Support BAU operations and incidents, getting stuck in when things break.
* Troubleshoot network issues end‐to‐end, from simple connectivity problems through to complex identity and security‐related faults.
* Administer and secure Linux OS environments, including access, patching, and troubleshooting.
* Support and maintain Microsoft GSA configurations and policies.
* Manage and support Azure tenants, with a focus on security and operational stability.
* Work closely with network, infrastructure, and security teams to resolve issues properly, not just put band‐aids on them.
* Document what matters and help improve how we do things.
What we're looking for
* Strong experience with high‐paced real operational environments.
* Solid Linux administration and security skills.
* Background in security operations and support, not just project work.
* Strong networking fundamentals and confidence troubleshooting issues at all levels.
* Hands‐on experience with Microsoft GSA.
* Strong working knowledge of Microsoft Entra ID, especially Conditional Access and identity controls.
* Comfortable dealing with incidents, escalations, and messy real‐world problems.
Nice to have
* Experience with Cisco Web Security Appliance (WSA) and Web Application Firewall.
* Experience with Cisco Email Security Appliance (ESA).
* Experience working in critical infrastructure environments.
* Exposure to Zero Trust concepts.
