At CGI, we empower our members to shape the future of secure digital infrastructure that supports critical missions and national resilience. As a Technical Author within our Compute Infrastructure team, you will transform complex technical information into clear, accessible documentation that helps users in demanding environments operate with confidence. Your work will play a vital role in ensuring mission readiness—delivering clarity, precision, and usability across advanced computing systems. You’ll collaborate closely with engineers and solution architects, turning innovation into actionable guidance that drives real-world impact while working in an inclusive, collaborative environment that values your creativity, ownership, and 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 position is based on site near Gloucester.
In this role, you will be responsible for developing, maintaining, and improving high-quality technical documentation that enables users—often operating in challenging environments—to effectively deploy and maintain complex computing solutions. You will work closely with engineers, system architects, and project teams, translating detailed technical designs into practical, user-friendly materials that enhance operational performance and knowledge sharing.
You’ll take ownership of documentation lifecycles, apply creativity in developing consistent templates and style guides, and be supported by a collaborative team dedicated to delivering excellence in every output. Your contribution will ensure our solutions are accessible, reliable, and ready for use wherever they’re needed.
Key responsibilities include:
Lead & Deliver: Author, edit, and maintain clear, accurate documentation across compute infrastructure systems.
Collaborate & Innovate: Work with engineering and project teams to gather insights and ensure accuracy of all materials.
Translate & Simplify: Turn complex concepts into clear, step-by-step guidance suitable for non-technical audiences.
Standardise & Control: Maintain document templates, version control, and consistency in line with defence standards.
Support & Enable: Contribute to training materials and knowledge bases to enhance internal capability.
Optimise & Improve: Ensure documentation supports offline usability and meets mission-critical operational needs.
To succeed in this role, you’ll bring a blend of technical understanding, precision in writing, and the ability to communicate clearly to diverse audiences. You should be comfortable working across hardware, operating systems, and virtualised environments, with strong attention to detail and commitment to quality.
You should have:
Proven experience as a Technical Author or Technical Writer in an IT or infrastructure environment.
Strong understanding of compute, virtualisation, and containerisation technologies (e.g., Linux, VMware, OpenShift, Kubernetes).
Experience documenting monitoring tools such as Nagios or CheckMK.
Ability to translate complex technical information for non-technical audiences.
Familiarity with defence or highly regulated documentation standards is advantageous.
Excellent written communication and document lifecycle management skills.
