The Opportunity

We are looking for an experienced Lead AI Architect to join a leading Technology & Transformation consultancy, working on some of the UK's most complex and high-profile Security, Justice and Public Sector programmes.

This is an opportunity for someone who wants to move beyond AI experimentation and Proof of Concepts. You will play a leading role in architecting and delivering production-grade AI systems , helping clients take Generative AI and Machine Learning solutions from initial concept through to secure, scalable and operational services.

You will combine deep technical expertise with consulting, delivery and leadership experience. Working closely with senior client stakeholders and multidisciplinary engineering teams, you will translate complex business challenges into practical, robust and cost-effective AI solutions.

This is a hands-on technical leadership role, ideal for someone currently operating as a Lead AI Architect, Principal AI/ML Engineer, AI Engineering Lead, Principal Architect, AI Practice Lead or similar , and looking to take the next step into an Associate Director-level position.

The Role

• Design end-to-end, scalable and secure AI architectures for complex enterprise and public sector environments.
• Lead the development and deployment of production-grade Generative AI and Machine Learning solutions.
• Architect systems integrating LLMs and ML models into wider enterprise applications and workflows.
• Oversee the full technical lifecycle, from solution design and model selection through to deployment, monitoring and continuous improvement.
• Design and implement robust MLOps and LLMOps practices, including CI/CD, model monitoring, evaluation and governance.
• Deploy and optimise models using cloud-based AI services such as AWS Bedrock, Azure AI Foundry and other AWS, Azure or GCP services .
• Work with self-hosted inference and model-serving technologies where appropriate, including tools such as vLLM, SGLang and Ollama .
• Design evaluation, observability and monitoring frameworks to assess model performance, system health, reliability and business impact.
• Optimise AI solutions for performance, scalability, security and cost-efficiency.
• Identify where AI can deliver genuine value and, equally importantly, recognise when a simpler engineering solution is more appropriate.
• Translate high-level client requirements into technical architectures, delivery roadmaps and actionable engineering plans.
• Identify and mitigate technical risks, including security, deployment and operational challenges.
• Lead and mentor multidisciplinary teams of AI Engineers, Machine Learning Engineers, Data Scientists and Software Engineers.
• Engage with senior stakeholders and communicate complex technical concepts to both technical and non-technical audiences.
