Lead AI Solutions Architect

Salary: £68,000 - 108,000 per year

Requirements:

• Deep knowledge of modern AI architectures on AWS, including Generative AI, RAG (Retrieval-Augmented Generation), and large-scale asynchronous inference workloads.
• Ability to translate enterprise business problems into AI-driven products, promoting decentralized model ownership while maintaining central standards for safety, evaluation, and reliability.
• Expert-level experience designing and operating AWS/Databricks with strong mastery of Model Serving, Vector Search, and the integration of Foundation Models.
• Strong understanding of AI security architectures, including private model endpoints, PII masking/redaction in prompts, IAM least-privilege for model access, and secure data egress/ingress for external LLM providers.
• Strong understanding of Infrastructure-as-Code (Terraform) and containerization (Docker, Kubernetes, Helm) to architect scalable, reproducible, and environment-agnostic AI platforms.
• Experience optimizing for GPU-accelerated compute, distributed model training, and high-availability inference services.
• Hands-on experience applying MLOps and LLMOps principles, including automated model evaluation, drift detection, CI/CD for model weights/code, and operational resilience of real-time inference APIs.
• Demonstrated ability to apply AI FinOps (Token Economics), managing cost-performance trade-offs between proprietary LLMs and fine-tuned open-source models.
• Proficiency in AI-native development workflows, utilizing Agentic IDEs and LLM-driven code generation to rapidly prototype, iterate, and deploy production-grade AI components.
• Proven experience designing multi-agent orchestration workflows (e.g., LangGraph, CrewAI) and utilizing MCPs to bridge the gap between LLM reasoning and enterprise data actions.

Responsibilities:

• Act as the primary AI solutions architect and trusted advisor for the business function, supporting initiatives from ideation through to production.
• Ensure enterprise Data, ML, and AI architecture principles are applied pragmatically to deliver measurable business value.
• Partner with business stakeholders, product managers, and engineering teams to understand business use cases and constraints.
• Design and document end-to-end AI system architectures aligned with enterprise standards.
• Review and guide solution designs to ensure they are secure, scalable, resilient, and cost-effective.
• Work closely with domain leadership to help shape domain data and AI strategy and roadmaps.
• Act as the voice of the business domain within the central Enterprise Architecture and AI communities.
• Provide structured feedback to central teams to evolve enterprise blueprints, platforms, and governance models based on practical experience.
• Represent the business function in Central Design Authority and architectural review forums.
• Ensure solutions meet enterprise security, AI governance, and AI risk standards while remaining delivery-oriented and scalable.
• Champion architectural best practices, data literacy, and AI-responsible design within the business function.
• Balance governance with enablement, ensuring standards accelerate rather than hinder delivery.
• Proactively identify opportunities where data, ML, and AI initiatives can deliver significant business value.
• Advise on MLOps, LLMOps, and AgentOps principles, and prioritisation and sequencing of initiatives based on feasibility, impact, and architectural readiness.
• Support the maturation of the domains data product and AI operating model.
