Moore, a former Unilever global brand vice president, will join the Engine-owned agency on 2 August.
He will sit alongside Penny Herriman, WCRS managing director, and Leon Jaume, WCRS executive creative director.
His remit will include “focusing on the next stage in the WCRS strategic vision.”
Moore’s appointment follows the recent announcement that Simon Clift, former Unilever Global chief marketing officer, has joined Engine’s board of directors.
Debbie Klein, Engine’s joint chief executive and WCRS chairman, says: “Moore brings a new dimension to the WCRS planning and creative product and will be central in building the future of WCRS.”
Moore adds: “I am passionate about building great brands and excited to be taking on a role where I can do that from an agency perspective for the first time.”
Unilever bought the personal care business of Sara Lee for €1.27bn (£1.16bn) last year.
Clift’s replacement Keith Weed is profiled in this week’s issue of Marketing Week.
