Why this role mattersAt Rebel, we’re in the middle of a bold reinvention. We were early to the cloud (hello, AWS circa 2016), and we’ve kept our hands on the wheel ever since—constantly experimenting, optimizing, and evolving how we serve our customers. Now we’re looking for someone who’s ready to help us take it further.This isn’t just a support role. You’ll be embedded in a tight-knit, nimble team of engineers and developers, working across both live production and new cloud-based infrastructure. From web hosting to email, DNS to domain management, you’ll help power the services that keep thousands of websites online—and make sure they’re fast, secure, and future-proof.You’ll be the kind of person who enjoys being in the thick of things: hands-on, proactive, quietly confident in your problem-solving, and motivated by a desire to keep improving. If you’re the one your team relies on when something’s on fire, this is your kind of place.What you’ll do
  • Provide second-level technical support for websites, applications, and email services
  • Handle occasional after-hours support (about 1–2 incidents per week)
  • Maintain and improve our hosting platforms: Plesk, Managed WordPress, Virtuozzo VPS, and more
  • Own and optimize our infrastructure stack—AWS, Ghost and others
  • Support and streamline customer migrations
  • Monitor system performance, troubleshoot issues, and resolve them efficiently
  • Proactively track costs and propose ways to deliver more value with less spend
  • Administer Linux/Unix and Windows environments
  • Manage and tune database systems (MSSQL, MySQL)
  • Write and maintain scripts using Bash, Python, Perl, or JavaScript
  • Use infrastructure-as-code tools like AWS OpsWorks
  • Contribute to IT operations process improvement and documentation
What you bring
  • Strong systems administration skills and a love of clean, scalable infrastructure
  • Deep knowledge of core network protocols and services: TCP/IP, HTTP/S, DNS, SSL, firewalls, load balancers, etc.
  • 5+ years of DevOps or sysadmin experience in Linux and Windows environments
  • 5+ years working in AWS cloud environments (EC2, VPC, ELB, EBS, S3, RDS, Route53)
  • Hands-on experience with scripting and automation
  • Familiarity with Agile/Scrum and modern CI/CD practices
  • A mindset for performance, optimization, and reliability
  • A collaborative attitude—you support what you build and help others level up too
  • A degree in Engineering, Computer Science, or a related technical field
Our approach
  • We build things to last: simple, testable, maintainable
  • We stay curious: always experimenting, always learning
  • We value impact over ego
  • We help each other out, and celebrate wins together
  • We take action—even when things aren’t perfect yet
