Systems Administrator
Job Summary
Title - Systems Administrator
Department - Client Support Services
Type - Full-time, permanent, salaried
Reports to - CTO
Location - Downtown Toronto office, with occasional client site work
As a Systems Administrator at Business Cloud, you are responsible for the security, availability, and recoverability of the systems our clients depend on across a portfolio of Microsoft 365 and Google Workspace environments. You remediate security findings, keep servers and network infrastructure patched and supported, verify that backups can be restored, and maintain consistent configuration across cloud tenants, identity, and endpoint management platforms.
Much of this work is proactive and does not start with a ticket. You find configuration drift, unresolved findings, and maintenance gaps through routine review, and you close them through direct work, automation, or coordination with other teams. Support handles frontline user issues; you own system-level problems and outages.
Your work falls into three areas:
Most work is performed remotely from our downtown Toronto office, with occasional on-site work for servers and network equipment. The role is client-facing. Some maintenance windows fall outside standard business hours.
Key Responsibilities
Security and Incident Response: Triage and remediate security findings and alerts from managed detection and response, Microsoft Defender, and endpoint security tools. Lead technical containment, eradication, and recovery during security incidents, preserving evidence and documenting findings and follow-up actions.
Backup and Business Continuity: Administer backup and continuity platforms, verify coverage and job health, and resolve problems. Perform and document testing, confirm restore readiness before major changes, and escalate continuity risks that cannot be resolved technically.
Server Administration and Lifecycle: Administer physical and virtual servers, including domain controllers, Hyper-V and VMware, directory synchronization, and remote and break-glass access. Coordinate patching and maintenance, validate service health, and plan upgrades.
Network, DNS, and Certificates: Administer firewalls, switches, wireless, and VPN infrastructure across different environments, including firmware and alert response. Manage DNS zones, mail authentication records, and certificate renewals.
Cloud Platforms and Identity: Administer client cloud environments, primarily Microsoft 365 and Google Workspace, along with Azure and related services, keeping tenant configuration, identity, and access policies consistent and secure. Manage privileged and emergency access through a documented, controlled process.
Health and Documentation: Monitor for configuration drift and correct it. Conduct proactive environment reviews and cleanup efforts. Own small non-billable changes. Maintain current documentation of systems, configurations, and their relevant procedures.
