Zusammenfassung

LS Instruments AG, now part of Postnova Analytics GmbH, seeks an Instrument Development Engineer to lead mechanical, thermal, and electronics engineering for advanced scientific instruments. The candidate will work on space instrumentation projects and a commercial product line, blending optics, mechanics and embedded electronics.

The role demands a Master’s or PhD in a related field, strong CAD skills (SolidWorks), and experience with instrument-scale thermal design.

Qualifikationen

• Graduate degree (Master’s or PhD) in mechanical engineering, mechatronics, physics, optics or related discipline.
• Experience working independently in a small cross-disciplinary team.
• Self-motivated and proactive in completing assigned tasks.
• Proficiency in 3D CAD (SolidWorks) for precision mechanical assemblies.
• Thermal analysis of instrument-scale systems: steady-state and transient modelling, TEC/Peltier control design.
• Prior experience in scientific instrumentation or laboratory equipment development.
• Understanding of how optical, mechanical, and electronic sub-systems integrate.
• Good written and spoken English.
• Swiss/EU citizenship or valid working permit for Switzerland.
• French and/or German language skills advantageous.

Aufgaben

• Mechanical and optomechanical design of scientific instruments: optical bench layouts and mounts.
• Thermal analysis and design of temperature control systems, including Peltier regulation.
• Electronics architecture definition: power distribution and cabling layouts for laser/detector systems.
• Resource budgets for system documentation and specs.
• Prototyping, testing, and design iteration with optics and software teams.

Jobbeschreibung

Your mission

• Mechanical and optomechanical design of scientific instruments: optical bench layouts, kinematic mounts, sample positioning mechanisms, structural enclosures
• Thermal analysis and design of temperature control systems, including thermoelectric (Peltier) regulation for sample environments requiring sub degree stability
• Electronics architecture definition: power distribution, signal routing, connector and cabling layouts for instruments combining lasers, detectors, and embedded computing
• 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 usLS 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.
