Descripción de la vacante

EY is seeking an experienced Solutions Architect to own target-state architecture for core banking transformation. You’ll define domain models, API/event contracts and non-functional controls to enable safe delivery, interoperability and AI-ready data exposure in regulated environments.

In this role you will lead architecture strategy, govern quality and security, and coach delivery teams while shaping proposals and reusable patterns across programmes.

Formación

• 8+ years in solution/domain architecture with significant core-modernisation experience.
• Mastery of domain-driven design, integration via APIs/events, and modern platform patterns (microservices, containers, cloud).
• Stakeholder leadership with CIO/Chief Architect/COO teams; crisp written architecture artefacts.
• Fluency in NFR engineering (resilience, security, observability) and release governance in regulated environments.

Responsabilidades

• Define target architectures for core and adjacent domains (customer, ledger, lending, treasury) with clear API/event contracts and data responsibilities.
• Lead strategic optioning and roadmaps (progressive modernisation vs replacement) with credible delivery pathways.
• Govern design quality and NFRs (availability, performance, security, operability); manage design risks and decisions.
• Embed AI-ready patterns (secure data/logic exposure, test harnesses, guardrails for non-deterministic components).
• Shape and deliver scalable, resilient, end-to-end solutions, ensuring designs are fully considered, robust and aligned to agreed architectural standards.
• Act as the conduit between business and technology functions; translate outcomes into clear design options and actionable plans.
• Provide high-quality guidance and documentation to enable a rapid, secure path from design to build/run.
• Contribute to business development: shape proposals, provide solution credibility in pursuits, and support mobilisation of wins.
• Develop people and communities of practice; coach junior colleagues and embed reusable patterns, assets and playbooks.

We help Financial Services clients navigate complex, technology-enabled transformations. If you’re excited by solving hard problems in a fast-moving environment, this is where your expertise makes a real impact.

Role purpose

Own the target-state architecture for core-banking transformation. Define domain models and contracts, API/event patterns and non-functional controls so delivery teams can build safely, interoperate reliably and expose data/logic for AI use cases without compromising resilience or compliance.

Your key responsibilities

• Define target architectures for core and adjacent domains (customer, ledger, lending, treasury) with clear API/event contracts and data responsibilities.
• Lead strategic optioning and roadmaps (progressive modernisation vs replacement) with credible delivery pathways.
• Govern design quality and NFRs (availability, performance, security, operability); manage design risks and decisions.
• Embed AI-ready patterns (secure data/logic exposure, test harnesses, guardrails for non-deterministic components).
• Shape and deliver scalable, resilient, end-to-end solutions, ensuring designs are fully considered, robust and aligned to agreed architectural standards.
• Act as the conduit between business and technology functions; translate outcomes into clear design options and actionable plans.
• Provide high-quality guidance and documentation to enable a rapid, secure path from design to build/run.
• Contribute to business development: shape proposals, provide solution credibility in pursuits, and support mobilisation of wins.
• Develop people and communities of practice; coach junior colleagues and embed reusable patterns, assets and playbooks.

Skills & experience – required

• 8+ years in solution/domain architecture with significant core-modernisation experience.
• Mastery of domain-driven design, integration via APIs/events, and modern platform patterns (microservices, containers, cloud).
• Stakeholder leadership with CIO/Chief Architect/COO teams; crisp written architecture artefacts.
• Fluency in NFR engineering (resilience, security, observability) and release governance in regulated environments.

Ideally, you’ll also have

• Experience across multiple core vendors and integration to channels, GL, risk and data platforms.
• Background in setting architecture review boards and guardrails for multi-vendor squads.

Success measures (KPIs)

• Design integrity and interoperability outcomes across programmes.
• Roadmap credibility and on-track delivery against architectural milestones.
• Reduction in defects/rework linked to architecture; NFR compliance.
• Uptake of reusable patterns and models by delivery teams.

What we offer

A competitive rewards package, flexibility in how and where you work, coaching and feedback from engaged colleagues, and opportunities to develop new skills (including access to technology learning pathways).
