Over 2 million food & beverage (F&B) businesses operate in the EU.


60% face failure within their first year


80% in five years.


SOUS is here to change that.


We’re building a platform that empowers independent F&B creators to thrive—unlocking new revenue streams, cutting costs, and scaling online growth with ease. From e-commerce to delivery management to building loyal communities, we’re reimagining how independent F&B brands grow in a digital-first world.


In just two years, we’ve scaled rapidly, onboarded top talent, and brought in over €8M in sales for our clients. Now, we’re evolving—transitioning to a SaaS-first model that will shape the future of the €100B independent F&B market.


To make this vision a reality, we’re searching for a Senior Full-Stack Product Engineer who’s as excited about building great products as they are about leading a team. If you’re ready to roll up your sleeves, write brilliant code, and influence the technical direction of a high-growth startup, we’d love to meet you.
