Description
Position Description
The Space, Defence and Intelligence business unit in CGI is a true IT Systems Integrator. We work, build, and operate bespoke, technically complex, mission-critical systems which help our clients keep us all safe and secure. We bring innovation to our clients using proven and emerging technologies, agile delivery processes and our deep expertise across the breadth of space, defence, intelligence, aerospace and maritime, all underpinned by our end-to-end cyber capability. We work collaboratively with global technology companies, cutting edge SMEs and academia to deliver the optimal solution for each client.
CGI was recognised in the Sunday Times Best Places to Work List 2025 and has been named one of the ‘World’s Best Employers’ by Forbes magazine. 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 will be based on sites near Chippenham and Reading 2/3 days a week.
Your future duties and responsibilities
As a Senior Test Manager at CGI, you will play a pivotal role in defining and delivering the Test Strategy and Test Plan for a high-impact migration programme. Working as part of a small, senior team, you will provide the client with clarity and assurance to shape future cloud migration activities. This position offers the opportunity to influence one of the client’s most significant technology transformations by setting robust testing standards from the outset. You will engage directly with stakeholders, collaborate with technical leads, and ensure all testing aligns with long-term strategic goals. Operating within a sensitive defence environment, the role requires HLC clearance, UK Sole Nationality, and site presence near Chippenham and Reading.
To succeed in this role, you will need deep expertise in testing secure cloud deployments, with strong awareness of infrastructure-as-code and its impact on testing approaches. You must be confident in engaging with senior business and technical stakeholders, translating complex testing concepts into clear, actionable insights. Previous hands-on experience leading migration testing of legacy systems into the cloud, particularly within Defence, is essential. A consultancy background is highly valued, especially in client-facing requirements gathering and assurance delivery. Familiarity with UK Government frameworks, DevSecOps practices, and holding active HLC clearance are critical prerequisites.
Life at CGI is rooted in ownership, teamwork, respect and belonging. Here, you’ll reach your full potential because…
You are invited to be an owner from day 1 as we work together to bring our Dream to life. That’s why we call ourselves CGI Partners rather than employees. We benefit from our collective success and actively shape our company’s strategy and direction.
Your work creates value. You’ll develop innovative solutions and build relationships with teammates and clients while accessing global capabilities to scale your ideas, embrace new opportunities, and benefit from expansive industry and technology expertise.
You’ll shape your career by joining a company built to grow and last. You’ll be supported by leaders who care about your health and well-being and provide you with opportunities to deepen your skills and broaden your horizons.
Come join our team—one of the largest IT and business consulting services firms in the world.
