Senior Systems Administrator – Level 2/3 Managed Services

Location: Midtown Toronto, ON

Work Arrangement: Primarily office-based with flexibility for remote work and scheduled client/site visits

Job Type: Full-Time, Permanent

Salary: $85,000 – $110,000 per year, based on experience and qualifications

About the Role

Our client is a growing managed IT and security services organization supporting professional services, legal, and commercial real estate clients across North America. They are seeking a Senior Systems Administrator to take ownership of complex client environments from day-to-day operations through project delivery.

This is a senior, client-facing technical role that combines systems and network administration, Microsoft 365, cybersecurity, managed services, and building technology environments. The successful candidate will serve as a senior escalation point for Level 1/2 technical issues while also providing day-to-day technical direction and mentorship to junior technicians.

The role offers broad exposure across multiple client environments rather than being dedicated to a single account, making it an excellent opportunity for an experienced MSP professional who enjoys variety, problem-solving, client interaction, and technical ownership.

Key Responsibilities

Systems, Network & Client Environment Management

Manage day-to-day network and systems operations across multiple client environments, including servers, firewalls, switches, Wi-Fi, and endpoints.
Serve as a senior escalation point for Level 1/2 technical issues and drive incidents through to resolution.
Lead patch management, firmware updates, maintenance windows, and infrastructure upgrades while minimizing business disruption.
Maintain accurate technical documentation, including network diagrams, credentials, run-books, and client environment information.
Support legal and professional services applications, including document and practice management platforms.
Provide hands-on technical support across diverse client environments.

Microsoft 365 Administration

Administer Microsoft 365 environments end-to-end, including Exchange Online, SharePoint, Teams, OneDrive, licensing, and user provisioning.
Configure and maintain Microsoft 365 security controls, including Conditional Access, MFA, Intune, Defender for Office 365, and Data Loss Prevention.
Manage Microsoft Entra ID/Azure AD, including hybrid Active Directory synchronization, user and group management, and single sign-on.
Lead and support migrations from on-premises infrastructure to Microsoft 365.
Monitor tenant health, licensing, security, and compliance across multiple client environments.
Maintain accurate documentation of Microsoft 365 configurations, licensing, and security settings.

Cybersecurity & Security Operations

Administer and maintain endpoint detection and response (EDR) solutions across client environments.
Monitor and respond to security alerts, investigate detection, and coordinate remediation activities.
Work with external managed detection and response/SOC providers on security investigations and escalations.
Ensure appropriate endpoint and network coverage across managed environments.
Support SIEM log source onboarding and monitoring.
Participate in vulnerability remediation, security posture reviews, and cybersecurity maturity initiatives.
Document security incidents, remediation activities, and lessons learned.

Managed Building Technology & OT

Support network and infrastructure operations across multi-building commercial property environments.
Manage servers, domain controllers, endpoints, networks, and operational technology (OT) systems.
Administer Nutanix hyper-converged infrastructure, including cluster health, virtual machines, and routine maintenance.
Support network segmentation and firewall management to isolate OT environments.
Assist with EDR/MDR monitoring and firewall log reviews.
Manage vendor remote access, including VPN provisioning, credential audits, and access registers.
Participate in vulnerability scanning, remediation tracking, and cybersecurity initiatives across building networks.

Team Leadership & Mentorship

Provide day-to-day technical direction to Level 1 technicians and help prioritize incoming work.
Review Level 1 ticket resolutions for quality, completeness, and adherence to documentation standards.
Act as the first escalation point for junior technicians.
Mentor and coach technicians on troubleshooting methodology and best practices.
Assist with onboarding and training new technical team members.
Identify recurring issues and drive root-cause solutions and process improvements.

Projects & Client Relationships

Lead or support infrastructure projects, including server migrations, Microsoft 365 projects, and building technology initiatives.
Develop strong relationships with client stakeholders and act as a trusted technical advisor.
Communicate technical information effectively to both technical and non-technical stakeholders.
Deliver a high level of customer service within professional, confidentiality-sensitive client environments.
Participate in strategic service delivery initiatives as the organization continues to grow.

Requirements

5+ years of experience in systems/network administration within an MSP or similar multi-client environment.
Hands-on experience with an RMM and PSA platform used for ticketing, SLA management, monitoring, and reporting.
Experience with platforms such as HaloPSA, NinjaOne, ConnectWise, AutoTask, or similar.
Experience administering Nutanix HCI, including cluster management and AHV/VM administration.
Strong experience with Microsoft 365 administration, including Exchange Online, SharePoint, Teams, and OneDrive.
Hands-on experience with Microsoft 365 security features, including Conditional Access, MFA, Intune, Defender for Office 365, and DLP.
Practical knowledge of on-premises Active Directory, Microsoft Entra ID/Azure AD, and hybrid environments.
Experience supporting or leading migrations from on-premises infrastructure to Microsoft 365.
Solid understanding of networking concepts, including LAN/WAN, VLANs, and firewalls. FortiGate experience is an asset.
Familiarity with EDR/MDR platforms and fundamental security operations concepts.
Experience mentoring, coaching, directing, or reviewing the work of junior technicians.
Strong client-facing communication skills with the ability to work comfortably with non-technical stakeholders.
ITIL Foundation certification or working knowledge of ITIL incident, change, and problem management is an asset.
Experience supporting law firms, professional services organizations, or commercial property environments is an asset.
Experience with operational technology (OT), building automation systems, or multi-site commercial environments is an asset.
Valid Ontario driver's license and reliable vehicle preferred.
Must be able to complete a criminal background check before employment successfully.
