The Role
In this position, you’ll take on a leading role managing Omni’s cloud security operations, ensuring our Microsoft 365 and Azure environment is monitored, protected, and continuously improving. You’ll work across Microsoft Defender, Sentinel, and Purview to detect, investigate, and respond to threats, while maintaining strong visibility over security events and risks.
Your day-to-day will be hands-on and fast-paced, combining threat monitoring, incident response, and proactive security uplift. You’ll analyse alerts, lead investigations, and coordinate response activities, while also tuning detections, improving logging and visibility, and strengthening controls across identity, endpoints, and data.
This role goes beyond reactive operations. You’ll play a key part in maturing Omni’s security posture by identifying gaps, improving processes, and embedding security into how we operate. Working within a small, collaborative ICT team, you’ll have the opportunity to shape our SecOps capability, ensuring it is practical, effective, and aligned to compliance and business needs. If you enjoy a mix of operational security, investigation work, and continuous improvement, this role offers the chance to make a real impact.
