• Vulnerability Remediation: Identify and address system vulnerabilities. Work toward raising compliance benchmarks (e.g., improving from 60% to 70%).
• Automation & Scripting: Develop PowerShell scripts for automation—monitoring services, generating patch reports, and tracking compliance.
• Endpoint Management: Use tools like Tanium and compare its effectiveness with SCCM in managing server environments.
• Security Collaboration: Partner with security teams to resolve real-time threats (e.g., CrowdStrike alerts) and support hardening initiatives.

• ITSM & Compliance: Manage change tickets through ServiceNow, aligning with ITIL frameworks (Incident, Problem, Change Management).
• Client Interaction: Engage directly with clients, explain technical solutions clearly, and support decision-making with pros/cons analysis.
• Team Leadership: Handle escalations, resolve team conflicts, and support a collaborative, solution-oriented environment.
• Directory Services: Provide support for Active Directory, Group Policy, and authentication services.

Qualifications:

• 8+ years of experience in Windows Systems Engineering in large-scale enterprise environments.
• Deep expertise with SCCM for server patching, deployment, and reporting.
• Strong knowledge of vulnerability management and server hardening practices.
• Proven ability to script and automate with PowerShell in real-world scenarios.
• Hands‑on experience with Tanium, and comparative understanding with SCCM.
• Working knowledge of ServiceNow for ticketing and change control.
• Proficiency in managing Windows Server OS (2016/2019/2022).
• Familiarity with security compliance tools and enforcing security baselines.
• Exposure to Azure and AWS in hybrid environments.
• Strong interpersonal and communication skills—comfortable working with cross‑functional teams and clients.

Bonus Skills & Certifications:

• Experience with Ansible for configuration management is a plus.
• Microsoft Certified: Azure Administrator or Windows Server Hybrid Admin Associate.
• CompTIA Security+ or equivalent security certification.
• ITIL v4 Foundation Certification.
