Respond to security incidents, conduct root cause analysis, and drive continuous improvement in incident response processes.
Collaborate with cross-functional teams to deliver technical workshops, training, and security awareness sessions for both technical and non-technical stakeholders.
Stay current with evolving threats, Microsoft security product updates, and industry best practices to proactively enhance the organization’s security posture.

Experience with security assessments, risk management, and remediation planning in enterprise environments.
Ability to communicate complex security concepts to both technical and business audiences.
Experience leading or supporting large-scale security projects and customer engagements.
Relevant Microsoft certifications (e.g., SC-100, AZ-500, MS-500, SC-300, SC-200) are highly desirable.
