Job description

At SOUS, we help independent food & beverage entrepreneurs grow. We’re building what we believe will be the last employee a restaurant owner ever has to hire that touches a screen. Our AI agent handles what matters most: being found, powering commerce, and bringing guests back.

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 (70%-80% of your time):

• 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.
• Scale and optimize cloud hosting on GCP (and AWS in the future).
• Ensure our stack is clean, scalable, and future-proof.

Product Engineering (20%-30% 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.
• Set the bar for code quality, testing (TDD/BDD), and CI/CD workflows.
• Mentor developers to help them grow while creating a culture of engineering excellence.
• Identify opportunities to innovate and improve.

Requirements

Hands-On Experience:

• You’ve been in the trenches as a full-stack developer for 10+ years, and you’re fluent in Python (Django) and JavaScript/TypeScript (React).
• You’ve built and scaled SaaS applications that are battle-tested in production.
• Your database game is strong - PostgreSQL and ORMs are second nature to you.

Leadership in Action:

• You’ve led teams, balancing writing code with mentoring and decision-making.
• You can architect systems that are both elegant and robust while keeping your hands dirty in the codebase.

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:

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

Frontend Know-How:

• Modern frameworks (React, MUI) are where you shine.
• You know how to make frontends fast, responsive, and delightful.

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.

Why SOUS?

• Competitive Salary + Equity: €95k + 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.
