The opportunity\n

At EY, you’ll have the chance to build a career as unique as you are, with the global scale, support, inclusive culture and technology to become the best version of you. 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.

\n

Lead market development and end‑to‑end execution of core‑banking transformation across Tier‑1/2 institutions. Shape strategy with CIO/COO stakeholders, define target platform architectures and orchestrate delivery so modernised cores expose secure APIs/events, operate with robust release governance, and provide a safe foundation for AI at scale.

Your key responsibilities\n

\n
• Market leadership & growth: build trusted executive relationships; lead pursuits/propositions; grow a healthy, diversified pipeline.
\n
• Pillar I — Enterprise Technology Strategy: set enterprise target states, options and value cases; rewire IT operating model and vendor/FinOps controls.
\n
• Pillar II — Domain Modernisation Architecture: define core‑banking target architectures, domain boundaries and interoperability patterns (APIs, event flows, domain contracts).
\n
• Pillar III — Technical Transformation Leadership: sponsor TMOs and large programmes; align fast‑cycle digital/AI to slow‑cycle core releases; assure risk, quality and controls.
\n
• Shape and deliver scalable, resilient, end‑to‑end solutions, ensuring designs are fully considered, robust and aligned to agreed architectural standards.
\n
• Act as the conduit between business and technology functions; translate outcomes into clear design options and actionable plans.
\n
• Provide high‑quality guidance and documentation to enable a rapid, secure path from design to build/run.
\n
• Contribute to business development: shape proposals, provide solution credibility in pursuits, and support mobilisation of wins.
\n
• Develop people and communities of practice; coach junior colleagues and embed reusable patterns, assets and playbooks.
\n

Skills & experience – required\n

\n
• Proven track record leading core‑platform modernisation and complex technology transformations in major banks or top‑tier consultancies.
\n
• Architecture authority across enterprise/platform design, API/event‑driven integration, resilience, security and cloud‑native patterns.
\n
• Commercial leadership from origination to close; adept at optioning, business cases and shaping multi‑year roadmaps.
\n
• Executive communication and stakeholder influence; comfortable at ExCo/Board committees on risk, spend and delivery decisions.
\n

Ideally, you’ll also have\n

\n
• Experience with progressive modernisation vs replacement pathways across major core platforms.
\n
• History of establishing architecture controls, release governance and model‑risk guardrails for AI‑enabled systems.
\n
• Prior responsibility for practice growth (offers, assets, communities) and senior team leadership.
\n

Success measures (KPIs)\n

\n
• Qualified pipeline growth and win rate across core‑banking modernisation.
\n
• Mobilisation speed and reduction in delivery escalations tied to architectural coverage.
\n
• Adoption of standard interoperability patterns (APIs/events) across programmes.
\n
• Stable senior coverage on strategic accounts; positive client NPS at C‑suite level.
\n

What we offer\n

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).
