As the Systems Administrator you will run the IT backbone of an entire family office group - servers, identity, virtualization, security, and second-tier support across multiple operating businesses. This is a hands-on, ownership-heavy role for an experienced sysadmin who wants real responsibility, modern infrastructure, and a security-forward team. You'll own the day-to-day operation of the servers, storage, virtualization, identity, and security tooling that keep the Lorval group running - and you'll have real latitude to harden the environment, automate the routine, and bring discipline to the work that matters most. You'll report to the Manager, IT Infrastructure & Security and work alongside the Network Administrator and IT Technicians. The IT Technicians handle tier-1 - your seat is for the work that needs more than a quick fix. Duties and Responsibilities • Server & Infrastructure Operations - Maintain and support the server, storage, virtualization, and SAN infrastructure that runs the Lorval group. Monitor performance and availability. Keep things running cleanly and catch problems before users do. • Identity & Access Management - Administer Active Directory and Entra ID - user accounts, group policy, conditional access, role assignments, and the rest of the identity surface that sits at the centre of every modern environment. • Microsoft 365 Administration - Own the Microsoft 365 tenant - Exchange Online, Teams, SharePoint, OneDrive, security and compliance configuration. Keep it tidy, current, and well-governed. • Security Hardening - Partner with the Manager, IT Infrastructure & Security on patching cadence, endpoint protection, and the day-to-day security hygiene work that quietly keeps the lights on. • Backup & Disaster Recovery - Run, test, and verify backup and recovery operations using Veeam, Acronis, or equivalent tooling. Treat a backup that has not been tested as a backup that does not exist. • Tier-2 Support - Take the escalations the IT Technicians can't close. Diagnose methodically, communicate clearly, and leave better documentation behind than you found. • Project Delivery - Lead and contribute to infrastructure projects - upgrades, migrations, new platform rollouts, and the larger initiatives the team takes on each year. • Documentation & Automation - Document what you build and what you change. Use PowerShell to automate repetitive work so it stops being repetitive. Required Qualifications • 5+ years of system administration experience in a professional environment. • Bachelor's degree in Information Technology, Computer Science, or a related field - or equivalent experience. • Hands-on experience administering Windows Server, Active Directory / Entra ID, and Microsoft 365. • Working knowledge of virtualization (VMware vSphere or Hyper-V), storage systems, and networking fundamentals (TCP/IP, LAN/WAN, VLANs, VPN). • Practical experience with backup and disaster recovery tools (Veeam, Acronis, or equivalent). • Disciplined approach to documentation, change management, and operational procedures. • Strong written and verbal communication - able to translate technical issues for non-technical stakeholders. • Strong troubleshooting, analytical, and problem-solving skills. • Strong organizational skills with a disciplined approach to documentation, operational procedures, and change management. • Ability to work independently and collaboratively within a team environment. • This role is a 100% in-office position and will require in-person collaboration with IT team members and business stakeholders across multiple operating companies. "Nice to Haves" • Security certifications (Security+, SSCP) or equivalent Microsoft certifications (MS-102, AZ-500). • Experience supporting multiple entities or business units within a parent organization. • Proficiency with PowerShell for automating routine administration tasks. • Familiarity with Nutanix, Linux, or manufacturing/industrial IT environments. We offer a comprehensive benefits package, including Medical, Dental, Drug coverage, and a RRSP matching plan.
