Infrastructure Engineer

About CGI

CGI has been recognised in the Sunday Times Best Places to Work 2025 and named one of the ‘World’s Best Employers’ by Forbes.

We offer a competitive salary, strong pension, private healthcare, and a share scheme (3.5% + 3.5% matching), making you a CGI Partner rather than just an employee.

We are committed to inclusivity and diversity, building a strong tech community and supporting careers across critical sectors, including the Armed Forces community.

This role sits within CGI’s Space, Defence and Intelligence business unit, focused on delivering secure, mission-critical systems for government clients.

Due to the secure nature of the work, candidates must either hold or be eligible for high-level UK Security Clearance (sole British nationality, 10 years UK residency, and strict travel limitations). The role is primarily onsite at a secure client location, 5 days per week.


Role Overview

As an Infrastructure Engineer, you will work within a fast-moving DevSecOps team delivering hybrid on-premise, cloud, and multi-cloud infrastructure solutions.

You will design, build, deploy, and support secure infrastructure environments using a wide range of modern cloud and automation technologies.

The role involves working across infrastructure, networking, security, and platform engineering in highly secure environments.


Key Responsibilities

  • Design, build, deploy, test, and support infrastructure solutions
  • Work across on-premise, cloud, and hybrid environments
  • Implement Infrastructure as Code using Terraform, Ansible, or CloudFormation
  • Support Kubernetes-based platforms and containerised workloads
  • Configure and manage Docker containers and images securely
  • Develop automation scripts (Python, Shell, etc.)
  • Support CI/CD and GitOps workflows (e.g. Argo CD)
  • Manage infrastructure security, compliance, and governance
  • Monitor systems and resolve infrastructure issues
  • Collaborate across DevSecOps teams and stakeholders
  • Support system performance, resilience, and networking improvements

Required Skills & Experience

  • ~3+ years infrastructure engineering experience (build, deploy, support)
  • Experience with cloud and on-prem infrastructure
  • Strong Kubernetes knowledge (pods, services, deployments, networking)
  • Experience with Docker (image creation, container management, security patching)
  • Infrastructure as Code (Terraform, Ansible, or CloudFormation)
  • Experience with cloud platforms (AWS preferred, also Azure/GCP)
  • Scripting skills (Python or Shell)
  • Experience with Git and Agile delivery environments
  • Understanding of infrastructure security and governance
  • Experience with monitoring tools (Prometheus, Grafana, ELK)
  • Strong troubleshooting and problem-solving skills

Desirable Skills

  • GitOps tooling (e.g. Argo CD)
  • Service mesh technologies (Istio, Linkerd)
  • CNCF ecosystem knowledge
  • Additional container orchestration tools (Docker Swarm, Mesos)
  • Broader platform engineering experience

Life at CGI
