• Follow vulnerabilities, misconfigurations, and operational findings through to closure.
• Improve tuning, automation, dashboards, and playbooks to raise alert quality and cut manual work, and help roll out new security tools and processes.

• Solid understanding of alert triage, endpoint security, identity risk, cloud security, and response workflows.
• Strong communication skills, a practical and straightforward approach, and the ability to work well with both technical teams and business stakeholders.
• Experience with Purview, EDI security, MSSP coordination, SIEM tuning, or automation is a plus. A bachelor’s degree in Cybersecurity, Information Systems, Computer Science, or a related field is preferred.
