At CGI, we’re redefining the standards of infrastructure reliability and performance across hybrid and cloud environments. As an Infrastructure Test Engineer, you’ll play a vital role in ensuring that mission-critical platforms are resilient, secure, and production-ready. Working at the intersection of infrastructure, automation, and quality engineering, you’ll help shape the foundations that keep organisations connected, scalable, and future-proof. This is your opportunity to make an impact through precision, collaboration, and innovation — delivering trusted infrastructure that drives real-world outcomes.

CGI was recognised in the Sunday Times Best Places to Work List 2025 and has been named a UK ‘Best Employer’ by the Financial Times. We offer a competitive salary, excellent pension, private healthcare, plus a share scheme (3.5% + 3.5% matching) which makes you a CGI Partner not just an employee. We are committed to inclusivity, building a genuinely diverse community of tech talent and inspiring everyone to pursue careers in our sector, including our Armed Forces, and are proud to hold a Gold Award in recognition of our support of the Armed Forces Corporate Covenant. Join us and you’ll be part of an open, friendly community of experts. We’ll train and support you in taking your career wherever you want it to go.

Due to the secure nature of the programme, you will need to hold UK Security Clearance or be eligible to go through this clearance. Please note this is a long-term role suited to Gloucester-based Partners able to commute daily to the client’s office (five days per week).

Candidate profile

In this role, you will take ownership of infrastructure quality across complex hybrid environments — designing, automating, and executing validation processes that ensure platform integrity and performance. You’ll collaborate closely with DevOps, SRE, and network specialists to embed testing excellence into every stage of delivery.

You will drive automation, integrate testing within CI/CD workflows, and use advanced monitoring insights to anticipate and resolve issues before they impact operations. Supported by a culture of collaboration and continuous learning, you’ll help shape robust infrastructure that delivers dependable, secure outcomes for CGI clients.

Key responsibilities:

• Design & Execute: Develop and run functional, non-functional, and performance tests for servers, networks, containers, and cloud platforms.

• Automate & Streamline: Build automated test scripts using Ansible, Terraform, Python, or Bash to validate infrastructure deployments.

• Integrate & Enhance: Embed automated testing within CI/CD pipelines using Jenkins, GitLab CI, or Azure DevOps.

• Monitor & Diagnose: Analyse logs and telemetry via Prometheus, Grafana, or ELK to detect anomalies and inform continuous improvement.

• Collaborate & Document: Work with platform engineers and SREs to define coverage, maintain traceability, and capture results for release assurance.

Required qualifications to be successful in this role

You should bring a strong technical foundation in infrastructure testing, automation, and validation — with a proven ability to ensure quality across hybrid and cloud environments.

Essential qualifications:

• Proven experience testing infrastructure platforms (compute, storage, networking, or virtualisation).

• Strong Linux/Unix skills and proficiency in shell scripting.

• Hands-on experience with IaC and automation tools (Terraform, Ansible, or Puppet).

• Familiarity with AWS, Azure, or GCP environments.

• Exposure to container technologies (Docker, Kubernetes).

• Understanding of network protocols, firewall configurations, and security best practices.
