Job description

Before you read another boring IT job posting…

Let’s be honest. You've probably read ten Systems Administrator postings today. They all say the same thing: Windows Server, Linux, AWS, great culture, competitive salary.

You don’t need another list. What you probably want to know is: who am I actually going to work for, and what kind of problems will I get to solve?

So instead of HR telling you about the role, here’s a conversation with the person you’d actually be working for, Juan, our Director of Technology.

An Interview with the Hiring Manager

Q: What are you actually looking for?
A: I want to grow the team to continue the evolution of our infrastructure and build new systems.

Q: What’s one of the biggest problems you’re trying to solve right now?
A: Finishing our hosting infrastructure evolution and optimization.

Q: What’s the day really like?
A: A mix of forward‑looking planned work, incident response, and client support—anything “systems” will need. There’s also a fair amount of ITOps work: endpoint management, office setup, vendor setup, and so on.

Q: What kind of person succeeds at Rebel on your team?
A: Somebody adaptable who’s ready to take on any challenge. We can do hard things — and that means anything. Our focus right now is Linux servers and AWS infrastructure, but we can expect a lot of different challenges in the future.

Q: What makes someone a bad fit?
A: Somebody who operates like a checklist and doesn’t want to move outside their box.

What You’ll Be Doing

• Managing Windows and Linux servers
• Supporting our AWS infrastructure (IAM, networking, compute, storage)
• Maintaining hosting platforms, Plesk, WordPress, and helping with migrations
• Managing endpoints and user access, including onboarding/offboarding
• Improving documentation and processes
• Troubleshooting production issues and participating in incident response
• Participating in on‑call rotation
• Strengthening our security posture, patching, access controls, audit logs
• Automating repetitive work whenever you can

You’ll get hands‑on with AWS, Plesk, and WordPress regularly, but those are things we can teach. What we’re really hiring for is underneath that.

What You Bring

Must have:

• A generalist mindset, comfortable moving between very different problems
• Strong networking fundamentals and protocols (DNS, HTTP, etc.)
• Linux system administration experience on production servers
• Familiarity with at least one public cloud (networking, user management)
• Scripting and automation ability

Very nice to have:

• AWS
• Configuration management / Ansible
• Git and version control

Nice to have:

• Virtualization
• Infrastructure‑as‑code / Terraform
• Incident management experience
• Security fundamentals
• Plesk
• WordPress
• Experience delivering training
• Hardware setup
• Practical AI usage

What Matters Most

• Take ownership
• Stay calm under pressure
• Communicate clearly
• Keep learning
• Like solving problems
• Aren’t afraid to say “I don’t know — but I’ll figure it out”

What We Offer

• CAD $70,000–$90,000 annually, plus benefits

NON‑SMOKERS ONLY PLEASE.
