• Manage user accounts, permissions, and policies in Azure AD and Active Directory
• Support firewalls, VPN connectivity, switching, and general networking issues
• Assist with server administration and maintenance across client environments
• Support VoIP and business phone systems

• Document troubleshooting steps and maintain accurate ticket notes
• Provide exceptional customer communication with clear and confident explanations
• Contribute to knowledge base documentation and continuous service improvement

Qualifications

• Strong customer facing technical support experience
• Proven troubleshooting ability across multiple client environments
• Excellent verbal and written communication skills
• Comfortable supporting users over phone and remote sessions
• Experience supporting virtual desktop infrastructure (Citrix required, VMware Horizon preferred)
• Experience supporting Microsoft 365 from an operational support perspective
• Solid networking and server troubleshooting fundamentals
Nice to Have
• Citrix certifications or hands on advanced administration
• Azure or Microsoft certifications
• Experience supporting security and endpoint management policies
• Exposure to multiple industry client environments
What Success Looks Like
