About NICCOS

Everyone talks about Shopify. We make sure it actually works.
NICCOS is a 15-person Shopify Plus agency based in Freiburg - focused on complex migrations, enterprise commerce, and conversion optimisation in the DACH region. 150+ migrations, typically 10–20% conversion uplift after launch, and up to 70% less ongoing engineering overhead. Our clients are established brands with seven- to nine-figure annual revenue - names like Groundies, MyCR7, and Smilodox.
No corporate theatre. No fluff. Real work.

Most Shopify developers build themes. You build systems. For us it is not about launching a pretty store - it is about making complex e-commerce architectures work: migrations from Magento, Shopware, and OXID, custom apps, middleware, and performance optimisation for brands that generate revenue every day.
As a Shopify developer at NICCOS, you work on projects that truly matter. No toy setups, no cookie-cutter theme tweaks - technically demanding solutions for enterprise clients who depend on your work.
You are not on your own: you work closely with our Head of Development, exchange ideas with the team, and have direct influence on how we are set up technically as an agency.
