As the Senior Infrastructure Engineer, you'll be responsible for the administration, security, availability, and performance of enterprise hosting and infrastructure environments. Work across on-premises, cloud, and hybrid environments while serving as a technical leader for complex client infrastructure, projects, escalations, and modernization initiatives.

Why This Opportunity Stands Out

• Serve as a trusted technical advisor for multiple client environments.
• Work across Windows Server, VMware, Azure, networking, storage, security, and backup.
• Lead infrastructure upgrades, migrations, cloud projects, and modernization initiatives.
• Own complex technical escalations and critical infrastructure incidents.
• Mentor junior technical staff and help establish infrastructure standards and best practices.
• Build leadership experience while remaining hands-on with enterprise infrastructure.

What You'll Do

• Design, implement, maintain secure, scalable, and highly available infrastructure environments.

What Makes You Successful: You enjoy solving complex problems and taking ownership of critical environments. Move comfortably between hands-on technical troubleshooting, infrastructure design, project leadership, and client communication. You stay calm during critical incidents, think strategically about long-term solutions, and can explain complex technical concepts to stakeholders.

What You'll Bring

• 7+ years of systems engineering/infrastructure admin and 3+ years of MSP experience.
• Windows Server, Active Directory, Group Policy, DNS, DHCP, PowerShell, VMware, vSphere.
• Strong networking knowledge across routing, switching, VLANs, VPNs, firewalls, and wireless.
