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 through data, automation and artificial intelligence.

Your key responsibilities

 

• Build and deliver AI and data solutions for financial services tax clients – developing data pipelines, models, automations and generative AI use cases under the direction of Managers. 

• Analyse, cleanse and transform complex, often unstructured tax datasets into well-structured, AI-ready data. 

• Contribute to solution design, testing, documentation and quality assurance to make sure our output is accurate, robust and high quality. 

• Engage directly with client teams and EY colleagues, building relationships and communicating your findings and recommendations clearly. 

• Supervise and support analysts and interns, sharing knowledge and reviewing their work. 

• Stay current with developments in AI, data engineering and tax technology, continually developing your own skills.
