Senior Full-Stack Product Engineer (Startup, SaaS, Amsterdam)
Posted Updated
Description
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 (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.
Benefits
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.
What to Expect in the Hiring Process:
1. A 30-minute intro call to get to know each other.
2. A 60-minute technical deep dive.
3. An technical assessment at our offices in Amsterdam.
4. A 30-minute cultural alignment chat to see if we’re a match.
