About us

LS Instruments AG, a spin-off from the University of Freiburg, is a technological leader in the field of optical characterization of nanoparticles. In July 2026, LS Instruments became part of Postnova Analytics GmbH , marking the beginning of a new chapter for our company. We recently received a contract to develop a modular light-scattering instrument for the aerospace industry.
In this context, we are enlarging our team and are looking for reinforcement. We are looking for a dynamic person to join us as an Instrument Development Engineer to take responsibility for the mechanical, thermal, and electronics engineering of our scientific instruments, starting with the space instrumentation project and continuing with our commercial product line.
