Who we are looking for
The Head of Enterprise Architecture owns the target-state design of the technology estate and the standards, patterns and governance through which it is realised. This is the architectural blueprint that determines how every platform, application and integration in the firm is built, connected, secured and retired.
The mandate is to reduce complexity while increasing optionality — cutting technical debt, rationalising a fragmented estate, and establishing the reusable architectural foundations that let engineering teams move faster within known-good boundaries. Success is measured not in documents published but in estate outcomes: fewer bespoke solutions, faster architectural decisions, demonstrably lower run cost, and an architecture capable of absorbing the pace of change that Frontier AI and post-quantum cryptography will impose.
A central element of this mandate is establishing the architecture that makes the firm AI-forward — the compute, serving, integration and control foundations on which AI becomes a governed production capability rather than a portfolio of experiments. This is delivered in deliberate partnership with the Head of Data & AI, who owns model strategy, data products and AI delivery.
This is a deeply technical leadership role. The successful candidate is a credible principal-level architect who has personally designed systems at scale, and who will lead through technical authority rather than positional mandate — equally effective authoring a reference architecture, defending a standard to a skeptical business-unit CIO, and presenting an estate rationalization case to the Senior Leadership.
What you will be responsible for
Architecture strategy & governance
Own the enterprise technology blueprint across infrastructure, cloud, security, data and application domains; maintain a coherent target state aligned to long-term business strategy.
Pattern portfolio & technology standards
Define, curate and govern the enterprise pattern library across infrastructure, cloud, integration, security and AI/ML domains, with a formal maturity model (Emerging / Validated / Strategic / Deprecated).
Publish a quarterly Technology Radar translating market signal into firm guidance on adopt, trial, assess and hold positions, with named executive accountability for retiring end-of-life technologies.
Define the AI infrastructure reference architecture — accelerated compute, model serving, inference optimisation, AI gateway and access-governance patterns — providing the substrate on which the Data & AI organisation delivers models and AI products.
Establish enterprise architectural standards for agentic systems: orchestration topology, tool-use patterns, human-in-the-loop escalation, and audit-trail requirements for AI-assisted decisions in regulated workflows.
Own the architectural control framework for AI — risk tiering, explainability requirements by use case, data provenance controls and output governance — ensuring deployments satisfy SR 11-7, EU AI Act and emerging supervisory expectations, jointly with the Head of Data & AI and the CISO.
Build the approved AI integration pattern set (RAG, document intelligence, structured output generation, model-in-the-loop workflows) so engineering teams build on validated foundations without bespoke review.

Organization & leadership
Education and preferred qualifications
Extensive, hands-on engineering and architecture career culminating in principal-architect or enterprise-architecture leadership roles, with demonstrable personal technical depth — not solely management tenure.
Deep expertise across cloud-native architecture, Kubernetes, distributed systems, event streaming, API and integration patterns, infrastructure-as-code and zero-trust security architecture.
Demonstrable depth in AI infrastructure architecture — model serving and inference optimisation, accelerated-compute cluster design, vector store selection and design, retrieval patterns and AI observability — sufficient to set standards and evaluate engineering decisions credibly.
Financial-services or comparably regulated experience, with working knowledge of SR 11-7, DORA, FFIEC, BCBS 239 or OCC Heightened Standards, and awareness of EU AI Act risk classification.
