Job description

We have an exciting opportunity for an AI Solution Architect to join our team on an initial 6 month fixed term contract, with opportunities for extensions. We are looking for a pragmatic, commercially aware Enterprise AI Solution Architect to lead the technical discovery and architectural definition of a new enterprise AI capability.

Working as the technical counterpart to the Product Manager, you will turn prioritised use cases into a target architecture, technical option recommendation, proof-of-concept approach and phased delivery roadmap. You must bring strong solution architecture skills across data, integration, cloud, security and generative AI, and communicate clearly with senior stakeholders.

In this role you will define a secure, reusable and scalable architecture enabling AI assistants and agents to access trusted organisational knowledge, data, systems, tools and workflows, with governance built in by design.

This is a hybrid working role based out of our head office in Central Birmingham.

You’ll be rewarded with:

• 33% discount across all M&B brands.
• 20% Friends & Family discount for up to five people.

• Define and assure proof-of-concept architecture and success criteria, present recommendations through M&B architecture governance and jointly develop the phased implementation roadmap.

What you will be delivering:

• Current-state architecture and technical gap assessment.
• Target and reference architecture, including key diagrams, data flows, trust boundaries and transition states.
• Enterprise AI architecture principles, reusable patterns, guardrails and non-functional requirements.
• Security, identity, privacy, governance and monitoring architecture.
• Service and operating model covering ownership, support, observability, change control and lifecycle management.
• Technical build vs buy vs partner assessment, including risks, costs, dependencies and resourcing evidence.
• Architectures, assurance findings and recommendations for priority proofs of concept.
• Phased implementation roadmap, architecture decision record and handover pack for delivery teams.
• Knowledge transfer to M&B Architecture, Engineering, Data, Cyber Security and IT Operations teams.
