The opportunity
EY Tax is a market leader, renowned for delivering sustainable growth and empowering our people to shape their own careers. Our diverse, collaborative team advises on high-profile transactions, combining technical expertise, innovation and a genuine focus on continuous development. Join us to work on challenging, multi-country projects in a supportive, dynamic environment where your impact truly matters.
Our Tax Technology and Transformation (TTT) team sits at the heart of EY’s Financial Services Tax practice, helping banks, insurers and asset managers reinvent how their tax and finance functions operate. We combine data engineering, intelligent automation and artificial intelligence – from AI-ready data foundations to generative and agentic AI – to transform tax compliance, reporting and advisory. As a Manager, you will lead multi-disciplinary teams to deliver these solutions, own trusted client relationships, and help shape our AI and data propositions in one of the fastest-moving areas of the market.
Your key responsibilities
- Lead the end-to-end delivery of AI and data engagements for financial services tax clients – scoping requirements, shaping the solution design, and managing delivery to time, budget and quality.
- Act as a day-to-day client lead and trusted adviser, translating complex tax, data and AI concepts into clear business value for both technical and non-technical stakeholders.
- Design and oversee AI-enabled and data-driven tax solutions – including generative and agentic AI use cases, data pipelines and models – ensuring they are robust, well-governed and ready for production.
- Manage, coach and review the work of Seniors, analysts and interns, building AI and data capability across the team.
- Support business development – shaping propositions, contributing to proposals and demonstrations, and identifying opportunities to grow existing accounts.
- Champion responsible AI, data governance and quality standards, staying abreast of developments in AI, tax technology and regulation and translating them into practical action.
