We are seeking a Senior Cloud Infrastructure Engineer to own and evolve a predominantly Azure-based infrastructure environment. This is a hands-on, senior-level individual contributor role with high autonomy and responsibility across cloud infrastructure, identity, endpoint management, and security. 

The right person serves as a technical authority across the Microsoft ecosystem, responsible for designing, operating, and continuously improving a cloud-first environment that supports a distributed workforce and field operations at scale. This role requires ownership, proactive communication, and the judgment to prioritize without constant direction.

• Perform patch management, vulnerability remediation, and security baseline enforcement across the server and endpoint fleet 

• Execute and maintain disaster recovery and backup procedures; participate in DR testing and unplanned outage response 

• Develop and maintain PowerShell automation to reduce manual operational overhead for the team 

• Document system configurations, architecture decisions, and change history; maintain operational runbooks 

• Participate in on-call rotation; support planned maintenance windows and off-hours patching 

• Act as escalation point for infrastructure issues from the broader IT team 

Required Qualifications 

• 5+ years of hands-on Windows Server administration in production environments 

• 4+ years of Azure IaaS experience - VMs, VNets, NSGs, Storage, Key Vaults, Azure Virtual Desktop 

• Strong Entra ID (Azure AD) expertise: RBAC, Conditional Access, identity governance, hybrid identity 

• Production experience with SQL Server and/or Azure SQL Managed Instances 

• Proficiency in PowerShell scripting for infrastructure automation and operational tooling 

• Experience with Microsoft 365 administration - Exchange Online, Teams, SharePoint 

• Familiarity with Microsoft Defender suite and endpoint security operations within M365 E5 

• Solid understanding of networking fundamentals (TCP/IP, DNS, firewall concepts, VPN, routing) 

• Demonstrated ability to work autonomously - self-direct priorities, manage workload without daily oversight 

• Strong written and verbal English communication skills; comfortable in vendor and stakeholder calls 

Preferred Qualifications 

• Fortinet experience - hands-on FortiGate administration or FortiManager familiarity is a strong differentiator 

• Microsoft Intune & endpoint management - Intune policy authoring, compliance baselines, app deployment across Windows and Android devices 

• Vulnerability management - experience with Defender Vulnerability Management or equivalent within the M365 E5 stack 

• Android / mobile device management - prior Zebra or ruggedized Android device deployment experience a plus given the active rollout

On-call expectations 

• Participation in a shared on-call rotation (~1 week every few weeks) 

• Occasional off-hours maintenance windows for patching and upgrades 

• Low-to-moderate incident volume, with a focus on proactive stability 

What Makes a Great Fit 

• You treat infrastructure as a product - documented, repeatable, and improvable over time 

• You proactively identify gaps and surface them with proposed solutions, not just problem reports 

• You can context-switch between strategic architecture discussions and hands-on troubleshooting in the same day 

• You communicate clearly with non-technical stakeholders and hold your ground constructively in vendor conversations 

• You are comfortable owning work streams end-to-end with minimal hand-holding 

Why This Role Matters 

• Own and shape a 99% Azure IaaS environment with minimal on-prem footprint 

• Drive improvements across identity, endpoint management, and security posture 

• Operate in a high-autonomy environment with direct impact on infrastructure direction 

• Work with enterprise-scale systems supporting thousands of endpoints and users 

• Influence standards, automation, and long-term infrastructure strategy
