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 Full-Stack Tech Lead 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.

Tasks

Code, Build, and Ship (50%-60% of your time):

• Create and improve APIs for users, orders, shipping, and partner tools.
• Build smart integrations with tools like Shopify and Mendrix.
• Scale and optimize serverless microservices on GCP (and AWS in the future).
• Ensure our stack is clean, scalable, and future-proof.

Lead, Inspire, and Strategize (40%-50% of your time):

• Architect and scale multi-tenant SaaS solutions for the next phase of SOUS.
• Collaborate with product, design, and operations teams to align technical plans with business goals.

• Mentor developers to help them grow while creating a culture of engineering excellence.
• Own the technical roadmap—spotting opportunities to innovate and improve.

Frontend Know-How:

• Modern frameworks (React, Material UI, React-Query) are where you shine.
