Job description

Position Title: Systems Administrator Team Lead
Location: Ottawa, ON (377 Dalhousie Street)
Work Model: Hybrid - 4 days onsite, 1 day work from home
About Rebel
OUR CUSTOMERS BRING A VISION - WE BRING THE PLATFORM TO SHARE IT ONLINE.
Our customers bring a vision. We give them the platform to share it.
Rebel helps people and businesses show up online. Domains, hosting, infrastructure. We keep it simple, reliable, and built to scale.
No unnecessary layers. No corporate theatre. Just smart people doing good work together.
Our manifesto: Be Thoughtful, Be Simple, Be Brave.
Role Overview
We’re hiring a Systems Administrator Team Lead to lead our Systems Team, responsible for reliable, secure, and scalable operations across IT, cloud/server infrastructure, hosting platforms, and Live Production Support (LPS). 
You’ll combine hands-on systems administration and platform engineering with people leadership—setting priorities, improving processes, and ensuring strong service delivery and operational excellence. 
What You’ll Do
  • Lead a small, sharp Systems team
  • Run agile workflows. Keep work moving and priorities clear
  • Own IT operations. Access, endpoints, processes, documentation
  • Drive security practices. Patching, access control, incident readiness
  • Manage AWS, servers (Windows & Linux), and infrastructure
  • Oversee hosting platforms (Plesk, WordPress)
  • Improve automation, DevOps, and deployment workflows
  • Strengthen uptime, monitoring, and disaster recovery
  • Participate in on-call and support production when it matters

What Matters Most
We can teach tools. We can’t teach mindset.
We’re looking for someone who:
  • Takes ownership and follows through
  • Stays calm under pressure and solves problems
  • Knows how to lead without overcomplicating things
  • Balances technical depth with practical decision-making

What You Bring
  • Experience leading a small technical team
  • Strong systems admin background (Windows + Linux)
  • Solid AWS experience (IAM, networking, compute, storage)
  • Exposure to DevOps practices and Git workflows
  • Experience with hosting environments (Plesk, WordPress)
  • Comfort with incident response and on-call environments

What We Offer
The opportunity to work in an atmosphere that truly rewards hard work and creative thinking.  We offer a competitive salary, benefits, and opportunities for growth and advancement within our company.
As if that wasn’t enough we also offer a smoke-free environment, a downtown location, a fully stocked fridge free for all staff. If Rebel sounds like the perfect workplace for you, there is only one question- What are you waiting for? 
Compensation
CAD $90,000 - $130,000 annually, plus benefits. 
How We Hire
As part of this recruitment process, we use automated or artificial intelligence–enabled tools to support the screening and assessment of candidates’ applications. All hiring decisions are made by our team.
