EY is hiring a Senior Manager – Core Banking Architect to shape the future of financial services technology. In this pivotal role, you will be responsible for owning target-state designs and domain boundaries for core banking, leading domain-driven design and interoperability efforts. You will act as the key conduit between business and technology, translating outcomes into clear, actionable plans while embedding AI-ready patterns and safe release governance into the architecture.
What You'll Do
- 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 modernization vs. replacement) with credible delivery pathways.
- Govern design quality and non-functional requirements (availability, performance, security, operability); manage design risks and decisions.
- Embed AI-ready patterns, including secure data/logic exposure, test harnesses, and guardrails for non-deterministic components.
- Shape and deliver scalable, resilient, end-to-end solutions, ensuring designs are 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.
What We're Looking For
- 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.
Nice to 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.
Benefits & Compensation
- A competitive rewards package.
- Flexibility in how and where you work.
- Coaching and feedback from engaged colleagues.
- Opportunities to develop new skills, including access to technology learning pathways.
