Informatie

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.

Tasks

Code, Build, and Ship

  • Develop and refine our core backend (Django) and frontend (React + TypeScript).
  • Create and improve APIs for users, orders, shipping, and partner tools.
  • Build smart integrations with tools like Shopify and Mendrix.
  • Set the bar for code quality, testing (TDD/BDD), and CI/CD workflows.
  • Identify opportunities to innovate and improve.
Requirements

Hands-On Experience:

  • You’ve been in the trenches as a full-stack developer for 3+ years, and you’re fluent in Python (Django).
  • You’ve built SaaS applications that are battle-tested in production.
  • Your database game is strong—PostgreSQL and ORMs are second nature to you.

Smart Development Practices:

  • Testing isn’t just a buzzword for you—it’s how you build (Pytest, React Testing Library).
  • You’re fluent in Git workflows and CI/CD tools (e.g., Bitbucket Pipelines).

API experience:

  • Experience in building and integrating APIs—whether it’s RESTful APIs, JWT Auth, or third-party tools like Shopify and Mendrix.

Frontend Know-How:

  • You know your way around React.

Bonus Points For:

  • Experience with Firebase (Auth, Hosting) or Google Analytics.
  • Building SaaS platforms and multi-tenant architectures.
  • A background in e-commerce, marketplaces, or scaling startups.
Benefits

Why SOUS?

  • Competitive Salary + Equity: €65k + options—you’ll grow with us.
  • Shape the Future: Your contributions will define what SOUS becomes.
  • Flexibility: While we’re primarily on-site, we value flexibility when it makes sense.
  • Passion-Driven Team: Join a group of foodies and techies who love solving big problems.
  • High Impact: Be part of a mission that’s changing the way F&B creators succeed.

What to Expect in the Hiring Process:

  • A 60-minute intro call to get to know each other and learn more about the projects you've worked on.
  • A take-home project (with a 90-minute review session).
  • A 45-minute cultural alignment chat to see if we’re a match.
  • Ready to make an impact? Let’s build something incredible together.
