Win new restaurants across Germany and help build one of our fastest-growing markets from the ground up. Full-time About SOUS SOUS exists to give independent restaurants the same acquisition-to-retention infrastructure that only chains and delivery platforms could previously afford. We build it as one connected data layer, replacing the fragmented stack most restaurants run today: a listings tool here, a separate storefront there, and no CRM at all. Spotlight owns discovery, as search shifts from Google links to AI assistants recommending where to eat. Commerce owns the transaction and, critically, the guest relationship that marketplaces have been extracting for a decade.

Our long-term bet is simple. As AI becomes the default interface for "where should I eat", the restaurants that own their guest data and their presence in that layer will keep the margin, and the ones still renting both from marketplaces will not. We are building the infrastructure to make the first outcome the default, not the exception. We are a team of 27, working from our headquarters on the Vijzelstraat in Amsterdam city centre, and we are growing fast across the Netherlands, Germany and South Africa. About the role SOUS helps independent food and beverage entrepreneurs grow by building what we believe will be the last employee a restaurant owner ever has to hire that touches a screen. After a strong start in the Netherlands, Germany is now one of our most important growth markets, and we are scaling our team there quickly. As Sales Manager Germany you bring SOUS to independent restaurants across the country. You are one of the first people building our German sales team, which means real ownership, a big market to win and a fast track to grow with it. Your team You join the Sales team Germany and re…
