What I'm looking for

I’m looking for SOC Analyst / Security Operations roles where I can run 24/7 and overnight coverage, perform Tier 1 alert triage and endpoint investigations, support IAM and secure onboarding, and document and escalate incidents in SLA-driven environments.

I support security operations for endpoint devices with hands-on experience in incident triage (Tier 1), security alert triage, and endpoint investigations. I work in SLA-driven environments to maintain operational continuity while enforcing security policy compliance and remediation.

In my recent roles, I’ve used CrowdStrike EDR, Microsoft Intune, Microsoft Entra ID, Zscaler, and BitLocker to monitor endpoints, remediate non-compliance, and support identity and access management workflows. I also assist with phishing detection and security awareness support, secure endpoint provisioning, and incident escalation documentation. I’m specifically seeking SOC Analyst / Security Operations work with availability for 24/7 and overnight shifts.
