Backend Developer / Programmer (f/m/d)

Shopify Themes
On behalf of our customers, we develop individual storefronts (also called themes in Shopify) for their online stores. In most cases, these are server-side rendered templates that are implemented with the Shopify template language Liquid and of course HTML, CSS and Javascript.
Shopify apps (plugins)
Extensions for Shopify are called Shopify Apps. These are plugins to add new functions to the system. We develop them in the backend using Ruby on Rails and React in the frontend. These are our own Shopify apps as well as plugins for other software providers and merchants.
Headless E-Commerce Architektur
A new trend in e-commerce is stores with sophisticated backend requirements. For this, we use Ruby on Rails to build robust, scalable APIs that power modern e-commerce experiences.
Custom backend solutions
We develop tailored backend solutions for complex e-commerce requirements, integrating various third-party services and ensuring high performance and security.
