Pasan SA designs and builds solar simulators that measure the performance of photovoltaic cells and modules, and is the reference in PV measurement, on Earth and in space, where our systems also qualify the cells and panels that power satellites. Together with our sister company Avalon ST, we supply LED and xenon flashers, thermal chambers, electroluminescence systems and complete test labs such as the Nexun range to the largest PV manufacturers, national laboratories, government agencies, certification bodies and research institutes worldwide. The roleWe are looking for an R&D and Service Engineer who enjoys both building new hardware and making installed machines run perfectly at customer sites. Roughly 70% of the time goes to development and 30% to service: installation, commissioning, calibration and troubleshooting, on site or remotely.The two halves feed each other. What you learn in the field shapes the next design, and what you design you will one day commission yourself.
Location: Neuchâtel, Switzerland, with travel to customer sites worldwide (about 20 to 30% of the year)
Occupation: Full Time - On Site
Reports to: CTO Start: as soon as possible
Responsibilities
Research and development Use AI tools throughout development, from design exploration and firmware and software coding to test analysis and documentation, to bring products to market faster Design and improve electronics for our simulators: LED driver boards, power stages, electronic loads, measurement and acquisition circuits Develop and debug embedded firmware for instrument control and data acquisition Build and run test benches to validate irradiance uniformity, spectral match, temporal stability and IV measurement accuracy Contribute to the PC control software, test protocols and calibration procedures Write technical documentation: schematics, test reports, user and service manuals Work with suppliers on component selection, obsolescence and second sourcing
Your profile
