• Managing SOC incident queues.
• Maintaining and improving asset baselines across customer environments.
• Producing clear, insightful reports for both technical and non‑technical audiences.

What you’ll bring:

• Hands‑on experience with Microsoft Sentinel and Splunk.
• Knowledge of the MITRE ATT&CK framework.
• Understanding of client‑server and multi‑tier applications, databases, firewalls, VPNs and endpoint security.
• Solid networking fundamentals (TCP/IP, LAN/WAN, HTTP, SMTP, FTP, LDAP, etc.).
• Strong analytical thinking and structured problem‑solving.
• An entry‑level cyber security certification (e.g. Security+, CEH, CPSA) or similar.

It would be great if you had:
