• Administer endpoint security tools (Microsoft Defender, EDR), assist in vulnerability scanning and remediation tracking, and support compliance evidence collection for audits (ISO 27001, SOC 2).
• Independently resolve complex Tier 2/3 escalations across servers, network, and infrastructure, diagnose and resolve authentication, connectivity, and platform issues, and develop and refine escalation playbooks and operational runbooks.
• Mentor Associate Systems Administrators on troubleshooting techniques and contribute to SLA/OLA monitoring for infrastructure services.
• Participate in Change Advisory Board (CAB) processes for standard and normal changes, maintain and audit the IT asset management (ITAM) database, and contribute to problem management investigations.
• Write and maintain PowerShell or Python scripts for IT operational tasks, automate onboarding/offboarding workflows using Entra ID and HR integrations, and build Power Automate flows for service request processing.
• Participate as a technical responder during infrastructure and service incidents, conduct root cause analysis, contribute to post-incident reports, and support on-call rotation coverage.
• Create and maintain standard operating procedures (SOPs), operational runbooks, and IT asset/configuration documentation.
• Execute against quarterly IT operational plans and team OKRs, and participate in cross-functional project teams as a technical contributor.

In addition to core responsibilities, the role is ideal for candidates who possess:
