Client Solutions Manager

DESCRIPTION

People changing the way brands connect with consumers — one experience at a time.

Delivering experiences rooted in emotion and inspiring people to become the voice of a brand has made Mosaic one of North America's fastest-growing sales and marketing agencies. We are a destination to tell stories and pave new paths to connect brands with consumers through experiential, retail, and digital interactions.

The Role

The Client Solutions Manager (CSM) leads a portfolio of concurrent client programs within Mosaic's New Business group as the senior day-to-day client lead for each engagement. This is a multi-program role, responsible for launching, running, growing, and, where appropriate, winding down multiple small- to mid-size programs simultaneously, each at a different stage of maturity. The role reports to the Director, Client Service — New Business.

The defining mandate is growth through conversion: turning temporary, seasonal, and pilot engagements into ongoing continuity programs, and scaling small programs into larger, dedicated ones. The CSM directly manages field leadership (Regional Managers and Field Operations Managers), owns each program's operational, financial, and client-relationship performance, and builds the playbooks and staffing models that let Mosaic spin programs up and down quickly and profitably.
