A Quebec success story
S3 is one of Quebec’s IT growth stories. 20+ years in Montreal. A team of 100. A portfolio of serious Quebec SMBs that have stayed with us for 10, 15, 20 years.
Recognized by our peers as one of the most technically solid MSPs in Quebec.
We didn’t grow through aggressive sales. We grew because we deliver. And our clients talk.
That’s the environment you’ll be working in.
The team you’re joining
A team of technical experts. Dedicated. Close to our clients. Tight with each other.
We push each other to learn. We trade what we know. We even hang out.
When somebody hits a complex challenge, we put our minds together. You’re surrounded by smart people. That’s what makes you grow.
Working side by side with people who are better than you on some things, and where you’re better than them on others.
This is the place where you make a massive leap in your technical knowledge.
A culture that puts the right things first
Two priorities at S3:
- Our clients’ satisfaction. They’re the ones who let us build this company. They come first, always.
- Our team’s well-being. Because without a strong, engaged team, we can’t deliver.
The founders are still here. Involved daily. Managers are super approachable. When you have an idea to make things better, you’re 100% heard.
What you actually do
You take ownership of client environments. You drive the evolution of Quebec SMB infrastructure: reliability, continuous optimization, security, documentation. You communicate directly with clients to keep what you’re building aligned with what they actually need.
You work shoulder-to-shoulder with co-managed client IT teams. Many of our clients have their own internal IT staff. You’re the technical counterpart on the other side — having real, detailed technical conversations, trading knowledge, solving problems together. Over time, you become the person they call when it counts. That’s why our clients stay with us for decades.
You step in where it matters. Critical incidents, complex problems, architecture challenges. You prioritize based on real client impact, not noise. There’s an on-call rotation, but our team in the Philippines absorbs most of the off-hours volume.
You take other sysadmins under your wing. You make sure they evolve. You teach them what you’ve learned. You contribute to our technical standards. A big part of this senior role is coaching the next generation of S3 talent.
We’re looking for someone who…
- Has 7+ years as a system administrator
- Has solid command of Active Directory, Windows Server, Microsoft 365 / Exchange
- Knows networking (LAN/WAN, firewall, Wi-Fi), virtualization, and cloud
- Has worked with Cisco, Dell, Fortinet
- Communicates well in French and English
- Is curious, proactive, solution-oriented
- Has a DEC or AEC in IT (or equivalent)
Bonus: MSP experience, PowerShell, Microsoft, Azure, or Fortinet certifications.
