Full job description

Advance your IT career. We are recruiting on behalf of our client for a Lead Systems Administrator & Architect

Work Location: Hybrid Montreal
Work mode: Remote (Toronto or Ottawa)
Salary range: $110,000- $130,000 depending on experience
Type of role: Permanent position

At MSP Corp, we don’t just build our own teams — we help our clients build theirs. As a national leader in managed IT services, we partner with exceptional companies to find the right talent to power their growth. We are currently supporting one of our clients in the search for a Lead Systems Administrator & Architect

About the Role

As the Lead Systems Administrator you will be responsible for the strategic design, implementation, and ongoing management of our server infrastructure, hosted primarily in Microsoft Azure. This role combines high-level system architecture with hands-on administration across Windows environments, ensuring the infrastructure is secure, reliable, and optimized for the company's evolving needs.

What You Will Do

Lead the ongoing design and implementation of improvements to our Azure infrastructure, ensuring that it remains scalable, secure, and cost-efficient. Collaborate with key stakeholders to identify areas for optimization, enhance system performance, and ensure the infrastructure evolves to meet changing business needs.
Oversee the administration of Azure resources, including virtual machines, storage, networking, and identity management. Ensure ongoing optimization for performance, security, and cost-effectiveness.
Manage day-to-day administration of Windows Server environments and Unix appliances, ensuring high availability, performance, and system health. Troubleshoot and resolve issues promptly, coordinating with other teams as necessary.
Leverage tools such as PowerShell, Azure Automation, and Ansible to automate repetitive tasks, streamline infrastructure management, and ensure efficient deployment processes.
Ensure the security of infrastructure by implementing robust access controls and adhering to best security practices for both Azure and on-premises systems. Collaborate closely with Security Ops to continuously monitor systems for vulnerabilities and ensure compliance. Coordinate efforts to remediate security issues and maintain a proactive, security-first posture.
Proactively monitor the performance of both Azure-hosted and on-premises systems, identifying bottlenecks, performance issues, and opportunities for improvement. Ensure systems scale effectively to meet business needs.
Ensure the ongoing health and availability of backup systems and disaster recovery plans. Monitor, test, and maintain existing backup and recovery strategies to ensure data integrity and business continuity.
Provide leadership and mentorship to junior system administrators. Share knowledge of best practices and cloud technologies to promote professional growth and team development.
Partner with development, operations, and other technical teams to ensure infrastructure aligns with application requirements and business objectives. Lead infrastructure projects and initiatives to support new services or major system updates.

What We Are Looking For

7+ years of experience in systems administration with a strong background in Azure and hybrid cloud environments.
Extensive experience managing Windows Server environments (Active Directory, Exchange Server, Hyper-V, etc.) and Unix-based systems.
Proficiency with Azure services, including VMs, AVD, App Services, Storage, Identity, Monitoring, Azure Active Directory, etc.
Strong experience with PowerShell, Azure Automation, Ansible, or other tools to automate and streamline processes.
Solid understanding of Azure architecture, with hands-on experience optimizing and maintaining cloud infrastructure for cost, performance, and scalability.
Strong troubleshooting and analytical skills, with the ability to resolve complex issues across both Windows and Unix environments.
Excellent interpersonal and communication skills for working cross-functionally with teams and stakeholders.
Microsoft Certified: Azure Solutions Architect Expert
Microsoft Certified: Azure Administrator Associate
