If you enjoy combining technical know-how with teamwork—and want to play a part in accelerating the energy transition at BA Wind—we look forward to hearing from you.

You will be based in Hamburg, Deutschland, with flexible working hours and a hybrid work model. A laptop will be provided, and the expected start date will approximately be April 2026. The role offers up to 20 hours per week during the semester, which can be increasing to 37 hours per week in the semester break.
