Role Overview 

We are seeking an experienced and pragmatic Manager of Infrastructure, Engineering & Architecture to take full ownership of a fragmented and underperforming IT estate. This is a critical role for a candidate who thrives in challenging environments, is confident rearchitecting legacy systems, and can deliver measurable improvements in performance, security, and stability. 

You will be responsible for managing and mentoring a small team of engineers, leading the modernization of infrastructure platforms, enforcing technical policies, and delivering a scalable and secure cloud-first environment. The ideal candidate will have a strong background in Azure, VDI, networking, and security, and will be comfortable operating with minimal direction. 

 

Key Responsibilities 

• Take ownership of all infrastructure services, including cloud, on-prem, network, endpoints, and user platforms. 

• 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. 

 

Required Experience 

• Strong experience remediating, rearchitecting, and stabilizing poorly implemented or neglected infrastructure. 

• Demonstrated leadership in hybrid or cloud-first environments using Microsoft Azure (ARM, conditional access, RBAC, policy, cost control). 

• Proficiency in building and managing VDI platforms, ensuring performance, resilience, and user adoption. 

• Deep understanding of networking, including Layer 2/3, firewall rule sets, VPNs, SD-WAN, and DNS/DHCP services. 

• Strong security mindset with hands-on experience in endpoint hardening, patching, device compliance, and access controls. 

• Experience implementing infrastructure-as-code and automation using PowerShell, Terraform, or equivalent tools. 

• Proven ability to lead engineering teams, drive accountability, and embed a proactive support culture. 

 

Desirable Skills 

• Microsoft certifications (AZ-104, AZ-305, MS-500) or equivalent cloud infrastructure credentials. 

• Security certifications such as CompTIA Security+, CISSP, or vendor equivalents. 

• Familiarity with identity federation, SSO, and device compliance within Microsoft 365 environments. 

• Experience with toolsets including Azure Monitor, Sentinel, Intune, Fortinet, Cisco, and backup/DR platforms. 

• Comfortable operating in regulated or multi-site environments with varied technical maturity. 

 

Candidate Profile 

• Hands-on and delivery-oriented, with a proven ability to solve complex infrastructure challenges quickly and effectively. 

• Excellent communicator who can work across technical and non-technical teams and articulate infrastructure strategy to senior stakeholders. 

• Strong documentation habits and a clear focus on building resilient, supportable environments. 

• Thrives in high-change, low-structure settings where initiative and technical leadership are essential.
