About easycosmetic

easycosmetic is a leading online shop for beauty products in the DACH region, the Netherlands, and Belgium. We offer over 40,000 products and utilize a completely in-house developed e-commerce platform. We handle all development internally: from the platform itself, product management, and logistics to SEO, AEO, GEO, and advertising.

Our management actively drives technological transformation, with an AI-First approach being a top priority. This isn't just talk; we live it daily. Claude Code is our primary development tool. We use the latest cloud-based models as well as local models on our own NVIDIA DGX Spark Cluster. Every architectural decision is guided by the question: "How can we solve this better with AI?"

You will shape this transformation – hands-on, with real impact on a system used by hundreds of thousands of users daily.
