Strategic Transformation - Manager EY-Parthenon, Financial Services, London At EY, we are committed to helping our clients shape their future with confidence in an increasingly uncertain world. As AI, technological advancements, shifting consumer preferences, and evolving geopolitical dynamics drive significant change, we stand ready to guide organisations through these complexities.

Our purpose is to build a better working world-not only for our clients and communities but also by providing our people with exceptional and challenging development opportunities that empower them to thrive.

Join EY and help to build a better working world.

The Opportunity EY-Parthenon is a leading global strategy consultancy and M&A practice, with over 25,000 dedicated professionals. Our core offerings involve helping clients to reimagine their business models through strategic advisory services, M&A execution and enterprise-wide, strategic transformation.

This opportunity relates to EY-Parthenon's Strategic Transformation practice, where we are making significant investment. We help Financial Services clients translate business strategy into an actionable transformation agenda, define where value will be created, and maintain the line of sight from strategic choices through mobilisation, delivery and benefits realisation.

Our Strategic Transformation mandates can be at Group level in a client's organisation or focused on a specific line of business or proposition. Across that spectrum, our work is:

• Strategy-led - focused on the priorities that matter most to clients: growth, efficiency and sustainable competitive advantage.
• End-to-end - connecting proposition and customer experience with the operating model, risk and controls, data and technology required to deliver them.
• Value-focused - ensuring transformation translates into tangible financial outcomes across P&L, balance sheet and ROTE.

We offer genuine opportunities to work on some of the world's highest profile strategic transformations in a market leading team. As we are making significant investment in this practice, we believe there are significant development opportunities for team members to help shape the practice and take early responsibility.

Your key responsibilities As a Manager, you will work with clients to solve complex strategic and transformation challenges, combining structured problem solving with a practical understanding of how change is delivered. You will play a central role in translating strategic ambition into actionable plans, while maintaining a strong focus on business value.

• Enterprise level efficiency and cost reduction programmes
• Set up and operation of Strategy Execution Office for client organisations

You will take responsibility for structuring work, managing day to day delivery and producing high quality client outputs, ensuring analysis translates into clear insights and practical recommendations.

You will manage workstream economics and proactively communicate progress, issues and risks to senior team members and client stakeholders.

Drawing on your Financial Services experience, you will build effective relationships with client teams, coordinate input from specialists across EY and supervise and coach junior team members.

You will also contribute to the growth of the Strategic Transformation practice by supporting proposals and business development activity, identifying potential opportunities through your client work, and contributing to the development of propositions and intellectual capital.
