• Lead the assessment, rearchitecture, and remediation of inherited infrastructure issues to establish a modern, secure, and reliable baseline
• Define and implement enterprise-wide technical standards, documentation, and operating procedures across infrastructure and endpoint management
• Manage and optimize a hybrid Microsoft Azure environment, including conditional access policies, identity management, and security controls
• Lead the design, performance tuning, and support of VDI environments (e.g. Azure Virtual Desktop, Citrix, or VMware Horizon)
• Ensure consistent and secure operation of all networking infrastructure including firewalls, VPNs, switches, and WAN connectivity
• Establish clear monitoring, patching, and incident response processes aligned with best practice and regulatory expectations
• Develop and deliver infrastructure roadmaps, collaborating with application, security, and service teams to support business goals
• Manage relationships with external vendors, MSPs, and tooling providers as required

Preferred Qualifications

• Microsoft certifications (AZ-104, AZ-305, MS-500) or equivalent cloud infrastructure credentials
• Security certifications such as CompTIA Security+, CISSP, or vendor equivalents
