• Resource budgets (mass, power, thermal dissipation) and technical content for system-level documentation and specifications
• Prototyping, testing, and design iteration of hardware in close collaboration with the optics and software teams

Your profile

• Graduate degree (Master’s or PhD) in mechanical engineering, mechatronics, physics, optics or a closely related discipline
• working independently in a small, cross-disciplinary team.
• self-motivated and proactive in concluding assigned tasks according to the company goals
• Proficiency in 3D parametric CAD (SolidWorks) for precision mechanical assemblies and mechanism design
• Thermal analysis of instrument-scale systems: steady-state and transient modelling, TEC/Peltier temperature control design
• Prior experience in scientific instrumentation, laboratory equipment, or analytical device development
• Understanding of how optical, mechanical, and electronic sub-systems integrate into a functioning instrument
• Good written and spoken English
• Swiss/EU citizenship or valid working permit for Switzerland

Experience in one or several of the following areas is advantageous:

• Electronics design (power distribution, PCB layout, low-noise signal conditioning)
• FEM simulation (structural or thermal)
• Optics, photonics, or laser-based measurement systems
• Space engineering standards (ECSS) or aerospace qualification processes
• Hands-on prototyping (3D printing, CNC, soldering, laboratory assembly)
• Good command of French and/or German

About us

LS Instruments AG, a spin-off of the University of Fribourg, is a technology leader in the field of optical characterization of nanoparticles. LS Instruments develops advanced scientific instruments for analytical applications in life sciences, food, personal care, and many more.

We have recently been awarded a contract by the European Space Agency (ESA) to develop a modular light-scattering instrument for the International Space Station. The PRISM-L Phase A feasibility study will be carried out by a European consortium led by SpaceApps (Belgium), with LS Instruments responsible for the Dynamic Light Scattering measurement module.

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 PRISM-L space instrumentation project and continuing with our commercial product line.
