Job description

Shape secure, data-driven solutions that help government clients tackle some of their most complex challenges.

As a Senior Data Engineer within CGI’s Secure Innovation team, you’ll turn complex datasets into trusted insight, with particular emphasis on Kibana visualisation and hands‑on data engineering.

You’ll take ownership of data quality and end‑to‑end flows, creatively solve technical challenges, and collaborate with experts to deliver secure, scalable solutions that make a measurable difference.

Working with modern technologies including Python, Elasticsearch, Kibana and AWS, you’ll have the freedom to innovate while being supported with ongoing learning and development to keep your skills at the forefront of an evolving technology landscape.

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 DV level UK Security Clearance or be eligible to go through this clearance.

This is a hybrid position and will require the holder to spend a minimum of 3 days a week on site in Central London.
