• Building and tuning high-quality detections across SIEM and security tooling.
• Carrying out proactive threat hunting and strengthening detection capabilities.

• Working closely with Cloud, Infrastructure and Engineering teams to enhance the organisation's security posture.

What they're looking for:

• Strong experience in Detection & Response or Security Operations.
• Hands-on experience with SIEM technologies, incident response and digital forensics.
• Experience working across hybrid cloud and on-prem environments.
• Someone who enjoys solving complex technical problems and driving continuous improvement.
• Exposure to Python, PowerShell or Bash would be beneficial.

This is an opportunity to join a business where you'll have real influence, work with cutting-edge technology and help shape the future of cyber security within a fast-paced, technology-driven environment.
