Position Description
At CGI, you’ll help strengthen the cyber resilience of critical UK programmes by building the data and detection capabilities that underpin an effective Security Operations Centre. Joining our Space, Defence and Intelligence business, you’ll work with customers and experienced colleagues to onboard secure cloud environments, engineer security data pipelines, and develop practical detection content. This is an opportunity to take ownership of meaningful technical work while expanding your skills across Oracle Cloud, Elastic, and other major cloud platforms. You’ll have the freedom to explore better ways of detecting threats, with the guidance and support of a collaborative team around you. Whether you’re developing your cyber career or ready for your next challenge, you can make a tangible contribution to protecting important services.
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 role requires full-time onsite working in Chippenham within a restricted working environment. Applicants who already hold Security Clearance are welcomed and will need to be willing and eligible to progress to a higher level of clearance where required. Additional payments are available for full-time onsite working and for working within the restricted environment.
Your future duties and responsibilities
In this role, you will join CGI’s Data and Detection Engineering team, supporting the onboarding of new customers into the Security Operations Centre (SOC). You’ll work directly with customers to understand their environments and requirements before helping design how security data is ingested into Elastic. With a primary focus on Oracle Cloud and opportunities to build exposure to AWS, Microsoft Azure, and Google Cloud, you’ll develop detection logic and triage guidance that enables the SOC to identify and respond to potential threats effectively.
