Senior Microsoft Systems Administrator / Technical Lead

Toronto, ON | Hybrid (3 Days In office) | 7+ Years | Day-1 Impact Required

The Hook

We are not hiring an administrator. We are poaching a superstar.

If you have spent years being the person everyone calls when the environment is on fire, when the migration is going sideways, or when the architecture needs to be rebuilt from the ground up—keep reading.

We need a technical heavyweight who does not need a 90-day ramp-up. Someone who can walk in on Day 1, open the hood, understand the environment, and start making it better immediately. If you are the type of engineer who automates before you are asked, documents before you are required, and leads before you are promoted—we want you.

This is not a maintenance role. This is a "come in and own it" role.

THE ENVIRONMENT

You will be joining a fast-growing cloud company that manages and operates business-critical systems—including Enterprise Resource Planning (ERP)—where downtime is not an option, security is non-negotiable, and environments must be predictable, resilient, and highly available.

You will be working in a complex, secure, virtualized, and hybrid cloud infrastructure that spans on-premises Windows environments, VMware virtualization, and Azure/AWS cloud services. You will be the highest escalation point for infrastructure issues, the architect for new deployments, and the mentor for the next generation of administrators.

The environment fosters learning and provides opportunities for growth across systems, cloud, cybersecurity, and networking. If you want to expand your skills while solving real,



high-stakes problems—this is the place.
