Job Description

NEW GROUND WON’T BREAK ITSELF.

Every day our teams help people in businesses and communities to do what is right and achieve their goals.

Our Business Risk Services (BRS) practice focuses on helping organisations manage risk, improve operational processes and realise strategic objectives. Our teams bring together deep sector knowledge with technical expertise to deliver internal audit, technology risk and assurance services to FTSE 100 and large, complex international organisations.

The Data, AI \& Analytics team provides audit, assurance and advisory services to Grant Thornton clients in the UK and internationally. We help organisations meet their data and AI obligations, strengthen governance and controls, and unlock value from advanced analytics and AI in a responsible, proportionate and business-relevant way.

As an Assistant Manager, you will take day-to-day responsibility for the delivery of client engagements across data and AI governance, managing fieldwork, financials and quality under the guidance of a Manager, while supporting the development of more junior team members. You will build strong working relationships with client stakeholders and start to build the network and experience needed to contribute to the growth of the practice.

We’re happy to talk flexible working and consider reduced hours and job shares — we’ll support you to balance your work and life.

• Build strong working relationships with clients and colleagues, demonstrating professionalism, curiosity and a commitment to quality in all interactions.
