Job Description

Tucows Domains is the world’s largest wholesale domain registrar, responsible for maintaining the health, neutrality, and openness of an important—but largely invisible part of the Internet: the domain name system (DNS). As a Senior DevOps / Systems Engineer at Tucows, you will be responsible for designing, building, and maintaining our hybrid infrastructure — spanning both on-premises environments and AWS cloud. You will lead the development, enhancement, and migration of systems infrastructure, collaborating with cross-functional teams to translate requirements into scalable, secure, and reliable solutions. In this role, you’ll be a technical leader, mentoring junior engineers, driving automation, and ensuring operational excellence across our platforms.

Job Responsibility

  • Architect, maintain, and enhance hybrid infrastructure across AWS and on-premises data centers
  • Lead migration projects, modernizing legacy systems and integrating them with cloud-native solutions
  • Collaborate with cross-functional teams to gather and analyze requirements and design scalable solutions
  • Build and optimize CI/CD pipelines using tools such as Jenkins, GitHub Actions, ArgoCD
  • Implement Infrastructure as Code (IaC) with Terraform and CloudFormation
  • Guide testing, monitoring, and incident response for production systems
  • Troubleshoot and resolve system issues, ensuring stability and performance across all environments
  • Oversee containerization and orchestration initiatives with Kubernetes (EKS, on-prem clusters), Docker, or ECS
  • Maintain hardware compatibility and integrations in on-prem environments
  • Stay current with emerging technologies in systems engineering, automation, and cloud services
  • Provide technical guidance and mentorship to junior engineers

Requirements

  • 8+ years of experience in systems engineering, DevOps, or site reliability roles
  • Proven experience with AWS infrastructure services (EC2, S3, RDS, VPC, IAM, CloudWatch, etc.)
  • Strong hands-on experience managing on-premises infrastructure, including virtualization (OpenStack or similar), networking, and storage systems
  • Proficiency with Infrastructure as Code (Terraform, CloudFormation)
  • Strong CI/CD pipeline development experience
  • Proficiency in one or more scripting/programming languages (Python, Go, Bash etc.)
  • Strong troubleshooting, incident response, and root cause analysis skills
  • Solid understanding of networking fundamentals (DNS, TCP/IP, routing, load balancing)
  • Strong Linux and Unix fundamentals, server automation, scripting, networking and security experience
  • Experience with configuration management tools (e.g., SaltStack, Ansible or similar)
  • Bachelor’s or Master’s degree in Computer Science, Systems Engineering, or a related field — or equivalent experience

What we offer

  • Remote-first work
  • Fair compensation and generous benefits
  • Commitment to inclusion across race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status or disability status
  • Reasonable accommodation for individuals with disabilities
