At CGI, we are shaping the future of responsible, scalable AI, helping organisations unlock measurable value, transform decision-making, and reimagine customer experiences. As an AI Specialist within our AI Practice, you will play a pivotal role in designing and delivering innovative AI solutions that solve complex business challenges across industries. Working at the heart of our UK & Australia business, you will turn emerging technologies into practical, high-impact outcomes, guiding clients from strategy through to deployment. Here, you will take ownership of meaningful work, apply creative thinking to real-world problems, and be supported by a collaborative community committed to delivering secure, ethical, and forward-thinking AI solutions.

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. Our teams operate within a flexible hybrid working model, however on-site requirements vary by project, so the ability to travel as required to meet client needs is essential.

Candidate profile

In this role, you will lead the design and delivery of end-to-end AI solutions that address complex business challenges and deliver measurable outcomes. You will work closely with clients and cross-functional teams to identify opportunities, shape AI strategies, and translate requirements into scalable, ethical, and secure solutions. From proof of concept to deployment and optimisation, you will take ownership of the full AI lifecycle, ensuring solutions are robust, compliant, and aligned to industry best practice.

You will apply advanced techniques across Machine Learning, Generative AI, Natural Language Processing, Computer Vision, and analytics, while mentoring colleagues and contributing to the growth of our AI Practice. By combining technical expertise with commercial awareness, you will turn AI innovation into tangible business value, supported by a collaborative and forward-thinking community.

Key responsibilities:

• Deliver end-to-end AI solutions from concept through to deployment and optimisation

• Shape AI strategies and roadmaps aligned to client objectives

• Design and build ML, NLP, Generative AI and advanced analytics models

• Experiment and refine models through structured testing and validation

• Ensure ethical, secure, and scalable AI architectures

• Translate complex AI outputs into actionable business insights

• Mentor colleagues, promoting innovation and knowledge sharing

• Stay ahead of emerging AI tools, frameworks, and methodologies

Required qualifications to be successful in this role

You will bring proven experience delivering AI solutions in a commercial environment, with strong expertise across Machine Learning, NLP, Generative AI, and advanced analytics. You should be confident designing scalable AI architectures, applying software engineering best practices, and communicating complex concepts clearly to technical and non-technical stakeholders. A postgraduate qualification in a relevant field is advantageous but not essential.

Essential qualifications:

• Proven track record delivering AI or ML solutions in industry

• Strong proficiency in Python and leading AI frameworks (e.g., scikit-learn, TensorFlow, PyTorch, LangChain)

• Experience with data engineering, MLOps, CI/CD, and containerisation (Docker, Kubernetes)
