Lead Data & Integration Architect

Position Description

At CGI, you’ll help shape the data foundations and integration capabilities that underpin major digital transformation programmes. As a Lead Data & Integration Architect, you’ll provide strategic architectural leadership across data migration, governance and enterprise integration, ensuring solutions are secure, scalable and aligned to business objectives. Working closely with programme teams, suppliers and stakeholders, you’ll influence critical design decisions, provide independent assurance and help manage the risks and complexities associated with large-scale ERP and technology change. This is an opportunity to play a key role in delivering lasting business value, driving architectural excellence and enabling successful transformation through effective data and integration strategies.

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 is a hybrid position but will require occasional trips to a client site in Mansfield.
