Strategic Transformation – Senior 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 Senior Manager, you will help senior clients make high-stakes choices and orchestrate integrated EY teams. You will combine strategy-grade problem solving with delivery pragmatism, ensuring transformation remains grounded in business value.
As part of your day-to-day role, you will lead complex workstreams, and where appropriate, smaller engagements, working with cross-functional teams in a high-pressure environment. Your client work will include design, planning and execution of strategic transformation, including:
- Business model reinvention (at enterprise or line of business level)
- New ventures (strategic partnerships, market entry)
- Proposition reinvention or launch of a new proposition
- Enterprise-level efficiency and cost reduction programmes
- Set-up and operation of Strategy Execution Office for client organisations
A key part of your role will be to manage engagement economics and communicate significant issues, fees and general progress to partners and clients.
Drawing on your technical skills and Financial Services experience, you will coach more junior team members and play a lead role in developing the team's intellectual capital.
You will also help build the capability and market profile of the practice, developing propositions and intellectual capital, contributing external perspectives and thought leadership, and strengthening connectivity across EY.
