Platform Engineer

Position Description

At CGI, we engineer secure, scalable cloud platforms that enable transformation across the UK’s most critical sectors. As a Platform Engineer, you will take ownership of designing and evolving resilient digital platforms that accelerate delivery and power mission‑critical services. Working across cloud infrastructure, automation, security, and observability, you will help set engineering standards and drive measurable improvements in reliability, performance, and cost efficiency.

Within a collaborative, multidisciplinary environment, you will have the autonomy to innovate, influence platform strategy, and continuously improve how we deliver for our clients — shaping modern cloud ecosystems that make a national impact.

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.
