About us

What can you expect at freshcells?

Designing, developing, and maintaining e-commerce applications is our business. Cutting-edge technologies, customers who want more than average, and a fun, vibrant team of over 40 web experts aged 20 to 50+ from five countries – plus seven office dogs. We also have a stylish office and rec room on the spacious premises of a former carpet factory in the heart of Dusseldorf.

We are vibrant and want to stay that way, and we always look forward to welcoming new colleagues. You should be able to communicate in English.
