Manager, Client Services (Private Equity) job at London Full Time

Every day, somewhere in the world, important decisions are made. Whether it is a private equity company deciding to invest millions into a business or a large corporation implementing a new strategic direction, these decisions impact employees, customers, and other stakeholders.

Consulting and private equity firms come to proSapient when they need to discover knowledge to help them make great decisions and succeed in their goals. It is our mission to support them in their discovery of knowledge.

We help our clients find industry experts who can provide their knowledge via interview or survey: we curate this knowledge in a market-leading software platform; and we help clients surface knowledge they already have through expansive knowledge management.

We’re hiring a Client Services Manager to help scale our Private Equity business at proSapient.

This is a hands-on leadership role for someone who thrives in high-pace, high-expectation environments and wants real ownership: of people, of clients, and of outcomes.
