DevOps Engineer / Platform Engineer, Senior

About Telesat Telesat is a leading global satellite operator, providing reliable and secure satellite-delivered communications solutions worldwide to broadcast, telecommunications, corporate and government customers. Backed by a legacy of engineering excellence, reliability and industry-leading customer service, Telesat has grown to be one of the largest and most successful global satellite operators.
We are seeking a Senior DevOps Engineer to own and evolve the cloud infrastructure and CI/CD platform for Telesat's Lightspeed satellite constellation. You will be responsible for the reliability, scalability, and automation of our Azure-based deployment platform, supporting a multi-technology monorepo (Java, Python, TypeScript, MATLAB) serving multiple development teams.
Cloud Infrastructure (Azure): Design, provision, and manage Azure cloud resources — primarily Azure Kubernetes Service (AKS), networking, storage, and identity — ensuring high availability and cost efficiency for satellite mission-critical workloads
Infrastructure as Code: Author and maintain Terraform modules to provision and manage all cloud environments (dev, staging, production), following DRY principles and modular design
CI/CD Pipeline Engineering: Own and extend GitLab CI/CD pipelines (merge request pipelines, merge trains, nightly builds, deployment workflows) across a polyglot monorepo. Ensure fast, reliable feedback loops for Java (Gradle), Python (Poetry/pytest), Matlab, and TypeScript (npm workspaces/Vite) build targets
Manage AKS cluster lifecycle including upgrades, scaling policies, and namespace isolation
Write and maintain Bash/Python scripts for deployment automation, environment provisioning, secret rotation, and developer tooling (pre-commit hooks, quality gates)
Operate and improve the monitoring stack (Grafana, Prometheus, Loki) to provide actionable dashboards, alerting, and log aggregation across all services
Implement and enforce cloud security best practices — network policies, RBAC, secret management, vulnerability scanning, and compliance controls for satellite communication systems
Collaboration: Work closely with backend, frontend, QA, and MATLAB engineering teams to unblock deployments, improve developer experience, and maintain platform reliability
Maintain runbooks, architecture decision records, and onboarding guides for infrastructure and deployment processes
5+ years of professional DevOps / Cloud / Platform Engineering experience

• Azure (AKS, Virtual Networks, Key Vault, Storage, Entra ID) — hands-on production experience
