Senior Solution Architect

Position Description:

CGI is looking for a Senior Solution Architect to shape the technical direction of major public and private sector digital transformation programmes. Working closely with client and CGI teams, you’ll turn strategic business needs into secure, scalable and resilient solutions that deliver lasting outcomes. You’ll take ownership of high-level architecture, influence critical technology decisions and bring creative thinking to complex integration and transformation challenges. As a trusted technical leader, you’ll connect business and technology stakeholders, guide multidisciplinary teams and help ensure solutions move successfully from design through delivery.

You’ll be supported by CGI’s collaborative community of experts while building your career across future client engagements and transformation programmes throughout the UK.
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 client-facing role, requiring regular attendance in Belfast, typically 1–2 days per week. Depending on the assignment, you may also be required to attend other CGI or client locations across the UK.

Your future duties and responsibilities:

In this client-facing role, you will lead the technical solution architecture for a complex, business-led digital transformation programme. You’ll work closely with client stakeholders, transformation teams and CGI delivery specialists to translate strategic objectives into robust architectural designs. You will take ownership of high-level designs, ensuring solutions are secure by design, scalable, resilient and capable of progressing successfully through security accreditation, detailed design and Technical Design Authority approval.

You’ll provide technical leadership throughout delivery, creating the space for teams to explore effective solutions while maintaining strong architectural governance. You’ll bridge business and technology conversations, manage technical risks and oversee implementation quality, supported by a collaborative CGI community.

• Own the end-to-end technical solution architecture and translate business requirements into deliverable designs aligned with transformation objectives.
• Create, maintain and evolve high-level architectural designs, diagrams, specifications and technical guidance.
• Ensure architecture is secure by design, scalable, resilient and aligned with security, data protection and regulatory requirements.
• Design integrations with existing and external systems, enabling effective data flow and interoperability while addressing risks and constraints.
• Provide technical leadership to development and Scrum teams and establish strong architectural standards and governance.
• Explain complex concepts clearly to technical and non-technical audiences and present designs and options to the Technical Design Authority.
• Identify technical risks early, develop mitigation strategies and escalate appropriately through programme governance.
• Oversee implementation quality, conduct architectural reviews and use feedback and emerging approaches to continually improve the solution.

Required qualifications to be successful in this role:

You will bring significant solution architecture experience within complex digital transformation environments, combined with the confidence to operate as a trusted technical adviser in a client-facing role. You should be comfortable owning architecture from business requirements through high-level design, governance and implementation, while collaborating effectively across business, delivery and technical teams.

• Extensive experience in Solution Architecture, ideally within large-scale digital transformation programmes.
• Strong experience producing high-level designs (HLDs) and comprehensive architecture documentation.
• Strong knowledge of enterprise integration, scalability, resilience, security and secure-by-design principles.
• Experience or strong knowledge of Salesforce, ideally including Salesforce Public Sector Solutions (PSS), and its wider ecosystem.
• Knowledge of MuleSoft integration technologies and Tableau.
• Proven ability to translate business requirements and operating models into practical technical solutions.
• Experience providing technical leadership to multidisciplinary development, delivery or Scrum teams.
• Strong understanding of architecture governance and experience engaging with Technical Design Authorities or equivalent governance forums.
• Proven ability to identify, communicate and mitigate technical, security and integration risks.
• Excellent stakeholder management skills, with the ability to communicate complex technical concepts clearly to senior and non-technical audiences.
• Ability to work collaboratively while taking ownership of architectural decisions and delivery outcomes.
