About this role

About Scento Scento is Europe's largest perfume decant website. Founded in 2024 and headquartered in Paris on Place Vendôme, with a second office in Berlin, Scento offers more than 1,000 original designer and niche perfumes from a roster of 200 houses as perfume decants: 2 ml, 5 ml and 8 ml vials plus a 30 ml bottle on most perfumes.
