What we offer

Your career at Kernkonzept

There are no fixed career paths at Kernkonzept. We want you to grow your career according to your talents and interests.​

We encourage you to acquire further specializations, whether in software engineering, product or key account management. We provide several days off and sponsor your choice of training.​

Our work is characterized by middle and longterm customer projects and our own product development. Short-term orders and tight deadlines do occur, but they are not part of our work ethic.​

We do not value rigorous project management routines. You will work in organically grown functional teams with sufficient time. ​

Our open, friendly working environment fosters learning and personal growth. Respect and cooperation are very important for us.​

Obviously there is a close proximity to hardware.​

Work with us

Do you fit into the team?

At Kernkonzept we work in an international team. You can and should speak English all the time. Get familiar with the cultures of our Canadian, Brazilian, Czech, or German colleagues!

We work with Linux OS and almost exclusively with open-source software. Some of us are conjurers with emacs – others with vim. There are keyboard enthusiasts who are discussing the advantages of red and blue Cherry MX switches, lovers of Douglas, Lem, or Pratchett, and walking movie lexicons. There are sporty spices who ride the Dresdner Heide with their fullies at lunch break or engage at triathlons in their free time.

Our engineers are literal veterans in the open-source software universe. Some have been providing the mirrors for German Ubuntu or Debian for years, or maintaining the Minicom program as a hobby – thus keeping open-source software tools running that are being used by thousands of users.

You feel proud to be a nerd and love the elegance of code? We could be your perfect match.
