At CGI, you’ll help shape the future of secure, scalable digital platforms that power critical services across the UK. As a Platform Engineer, you will play a central role in strengthening high-performance environments that enable agile delivery and continuous innovation initially for our major UK Government and Justice clients. You will take ownership of complex platform challenges, collaborate closely across multi-disciplinary teams, and apply creative problem-solving to drive automation, reliability, and resilience. Supported by a community of experts, you will contribute to modernising platforms that make a real impact while evolving your skills in an environment that values curiosity, initiative, and continuous growth.
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. This is a hybrid position with very occasional travel to one of our client’s sites in Newcastle, Bristol, Leeds and Telford.
In this role, you will maintain and enhance secure, resilient, and scalable platform environments that underpin continuous delivery for multiple teams. You will take ownership of platform health, proactively identifying improvements, strengthening automation, and ensuring the reliability and performance of core systems. Working closely with developers, security specialists, and infrastructure teams, you will help streamline CI/CD pipelines, embed secure-by-design practices, and support the rapid deployment of high-quality applications.
You will contribute ideas, trial new approaches, and be supported by a collaborative community as you help drive forward platform innovation, operational excellence, and continuous improvement.
Key responsibilities include:
• Lead & Innovate: Configure, manage, and optimise platform infrastructure to ensure high availability, scalability, and resilience.
• Develop & Deliver: Build automation for provisioning, deployments, remediation, and system maintenance using IaC and CaC.
• Monitor & Enhance: Implement advanced monitoring, analyse performance metrics, and optimise system capacity.
• Secure & Strengthen: Embed security controls throughout environments and CI/CD pipelines, ensuring compliance and automated vulnerability detection.
• Collaborate & Enable: Work with developers and security teams to streamline deployments and integrate secure DevSecOps practices.
• Resolve & Improve: Lead incident triage, troubleshoot issues, and introduce automated remediation where possible.
• Explore & Evolve: Research new technologies and integrate modern practices to uplift platform performance and reliability.
To succeed, you will bring hands-on experience in platform engineering or DevSecOps, with strong knowledge of cloud platforms, IaC, automation tooling, and secure development practices. You should be comfortable working across cross-functional teams, contributing to continuous improvement, and supporting mission-critical environments.
You should have:
• Extensive experience in platform engineering, DevSecOps, or similar roles.
• Strong understanding of cloud platforms such as Azure.
• Proficiency with container tools (e.g., Docker, Docker Swarm).
• Expertise with IaC tools (Terraform, ARM Templates).
• Experience with CI/CD tools (Azure DevOps, Jenkins) and Git.
• Knowledge of monitoring technologies (Prometheus, Grafana, Dynatrace).
• Proficiency in scripting (Python, Bash) and CaC tools (e.g., Ansible).
• Understanding of cloud and container security, automation tooling, and frameworks such as OWASP and CIS Benchmarks.
