Backend Symfony Developer

We are a dynamic scale-up and have been revolutionising the Swiss e-commerce market for over 5 years. With our unique platforms — from Brands for Employees to Brands for Students and the MyAXA Deals Platform — we offer exclusive access to leading products and services to closed communities.

With 80+ passionate team members (incl. IT, Business Operations, Sales, Finance) across Europe, we generate a mid double-digit million turnover and have grown at an average of 70% annually. Awarded the SEF.Growth High Potential Label by the Swiss Economic Forum, we’re on an ambitious journey and you know what — we’re just getting started 🚀.

We are now looking for a Backend Engineer with strong expertise in Symfony and Sylius to take ownership of building and evolving the core services behind our platforms. You will play a key role in shaping one of the most critical and impactful areas of our business: the systems that power our e-commerce platforms and internal ERP. As one of your first missions, you will work closely with our Lead Backend, CTO, and product teams to implement new features and extend existing applications — contributing directly to the scalability and reliability of our technology stack, a major milestone on our product roadmap.

Mission

Join us as a Backend Engineer (Symfony | Sylius) to build the services and APIs powering our commerce platforms and internal ERP. You will implement reliable, scalable backend features in PHP with Symfony and Sylius, helping us ship business-critical functionality at pace and quality. You report directly to our Lead Backend & CTO.

What makes this role unique? You’ll work across our customer-facing platforms (e.g. Brands for Employees, Brands for Students, MyAXA Deals) and our self-developed internal ERP system — extending existing applications and building new services from scratch to meet evolving business needs.
