• Support development teams across connected and disconnected environments, including use of cloud services where needed.
• Develop CI/CD pipelines, iOS signing/sideloading automation, and test infrastructure with containers and Infrastructure-as-Code.
• Monitor, troubleshoot, and improve infrastructure, observability, and network reliability to support developer productivity.
• Must be authorized to work in Canada or the U.S. without visa sponsorship and be willing to collaborate across global time zones.
• Eligibility to obtain security clearance.

Qualifications

• Bachelor’s Degree and minimum 4 years of prior relevant experience. Graduate Degree and a minimum of 2 years of prior related experience. In lieu of a degree, minimum of 8 years of prior related experience.

Preferred Additional Skills

• 8 years of experience in platform, infrastructure, or DevOps engineering, including disconnected/offline environments.
• Strong programming skills in Python and JavaScript, plus hands‑on Git and GitLab pipeline experience.
• Experience managing TLS certificates, reverse proxies, automation/orchestration tools, and headless browser automation.
• Practical experience with AWS S3, Linux administration, VMware vSphere, virtual machines, and Infrastructure as Code.
• Solid networking knowledge, including Layer 2 concepts like VLANs, switch configuration, and network troubleshooting tools.
• Comfortable working with Docker and Docker Compose.
• Broader AWS experience, such as EC2, Lambda, and Route 53.
• Experience supporting developers in disconnected environments.
• Familiarity with storage and object storage platforms like TrueNAS Scale and MinIO.
• Understanding of Layer 3 networking operations.
• Experience with Kubernetes, Ansible, Terraform, and other IaC tools.
• Familiarity with iOS build, code‑signing, provisioning, and side‑loading workflows.
