Jobbeschreibung

Vision to Products

Welcome to Hahn-Schickard: The research center for innovative microsystems technology. With a team of over 300 employees, we transform ideas into cross-industry solutions - from conception to production at three locations in Baden-Württemberg. At our Freiburg site, the emphasis is on developing analytical solutions in microsystems technology, particularly for point-of-care diagnostics.

At the Freiburg site, the focus is on analytical solutions, especially for point-of-care diagnostics. But we also research, develop and manufacture electrochemical energy systems, autonomous fluidic robots and 3D printing of electronics.

For our Laboratory Automation division, we offer at Freiburg im Breisgau the following position (beginning from November 2026 or later):
