However, jobs for postdocs are far rarer in companies than they are in universities and non-university research institutes in Germany. Nevertheless, engineers and natural scientists in particular often find a new home here after completing their doctorates.
If you are seeking a future in applied research, would like to see your results swiftly transformed into practical applications and regard the constraints of feasibility and economic viability as a challenge, then a research job in industry could be highly attractive. Here discoveries flow directly into new products or solutions. Teaching duties and the pressure to publish do not exist here.
However, that is also one reason why the path back into a university in Germany is not necessarily easy. You should therefore carefully consider a move to industry.
If you aspire to a career as a professor at a university of applied sciences in Germany, however, subject-related experience outside higher education is generally a mandatory. A postdoc position in a company then enables you to gain the practical experience and expertise required for a professorship at a university of applied sciences.
