What you'll do:

As a Senior Artificial Intelligence Engineer – Centre of Excellence at MUFG in London you will play a pivotal role in shaping the future of applied AI across global financial markets. Your day-to-day responsibilities will involve leading the design and delivery of mission-critical AI capabilities that require full enterprise controls. You will define technical standards that empower both citizen developers and function-aligned teams to scale their solutions safely while directly engineering complex cross-functional projects where risk or dependency demands central ownership. You will build reusable platform components that accelerate delivery across the organisation while maintaining rigorous governance over architecture reviews and release processes. Collaboration is key: you will partner closely with other engineers to unblock issues and promote best practices; engage with diverse stakeholders from compliance to operations; and ensure every solution is auditable and resilient. Success in this role means delivering measurable outcomes—productivity uplift, cost reduction and improved controls while maintaining impeccable quality in documentation and operational support.

• Lead the engineering design and delivery of high-risk, cross-functional enterprise AI capabilities for Global Markets outside Japan, ensuring all solutions meet rigorous architecture, security, governance and operational standards.

• Define, maintain and continuously improve engineering standards, reusable patterns, control requirements and reference architectures for responsible AI adoption within Global Markets.

• Own or support technical governance processes including intake management, risk classification, lane routing, architecture review, threat modelling, model evaluation, release approval and production monitoring.

• Build reusable platform components such as retrieval-augmented generation frameworks (RAG), agentic workflow patterns, connector templates, evaluation harnesses, audit trails and deployment packs.

• Partner with function-aligned engineers to review designs, resolve engineering challenges collaboratively, promote reuse of components and ensure local solutions remain aligned with Centre of Excellence standards.

• Enable citizen-led delivery by providing safe templates, guardrails, training materials, certification processes and controlled runtime patterns for distributed teams.

• Maintain high-quality inventory of production AI solutions with clear ownership documentation, data lineage tracking, access control protocols and robust monitoring systems.

• Design integrations between AI platforms and enterprise tools/data sources—including entitlement controls, DLP mechanisms, audit logging features and operational resilience requirements.

• Engage regularly with Technology, Cybersecurity, Risk Management, Compliance, Legal Affairs, Finance Operations and Front Office stakeholders to ensure all AI adoption is safe, supportable and aligned with regulatory obligations.

• Ensure every AI-enabled solution includes human oversight mechanisms such as explainability features, validation/testing routines, exception handling procedures and evidence capture proportional to risk.
