What is waiting for you

Together with our long-term partner Conrad Electronic we have created the ACDC (ACTUM Conrad Development Campus) project. This is not just another development hub, but a project where developers can learn and progress to new levels, becoming part of the prestigious Conrad family of developers. As one of the leading B2B supplier portals in Europe, and as one of the key strategic partners of Google, Conrad is not only a great company to work for, but a real innovator of new technologies.  

The position

As a horizontal service team in a mostly vertical oriented environment, we are working with Kanban. This means we offer support to every team regarding data (provisioning, migration, …).  We are always on it to improve our services and processes, and we are open to new technologies and tools which can help us do this. Following the principle “run what you build” we are fully responsible for our services. We provide data for the complete Conrad shopping platform, related systems and external customers or partners. We control our environment, infrastructure, processes, and architecture. With more and more data coming our way, we “process data for breakfast” making sure the teams can rely on us.

The team

A team of eight highly motivated developers with experience grades from senior, mid-level to junior. We are collaborating closely, supporting each other, and sharing knowledge. From a personal perspective we are very diverse, but we all share the same data mindset. We also work together with the other teams, especially Master Data Management, Price and Availability, Product, Search and Data Science.

Safe and proven handling of common tools, databases, technologies, etc. Good overview of state-of-the-art technologies and hot news regarding data processing, to improve and push our processes and architecture forward.

"After many years of working in corporations, I really enjoy the family environment in Conrad. I'm pleasantly surprised at how smart and friendly colleagues I have. Here in Conrad I can directly affect the quality of services provided to customers. As a developer, I really appreciate the freedom to choose tech stack. I can spend 10% of my time on anything I want: learning new technologies, researching my ideas or just working on a side project to relax from daily business."
