What they need
We are looking for a hardware developer with experience in the field of power electronics and the ambition and potential to develop their knowledge and contribute to the growth of our international team’s expertise.
🔧 TEAM AND PRODUCT
At KOSTAL Electro Mobility (KEM), we develop power electronics for electromobility, in particular on-board chargers (OBCs) and HV/LV DC/DC converters.
We work closely with colleagues in Germany and at other KOSTAL sites.
We design, prototype and test the equipment at the Prague R&D centre, where the entire product is developed through multidisciplinary collaboration between hardware, software, design and other specialist teams.
🛠️ WHAT YOU’LL BE DOING
You will be involved in hardware development throughout the entire development cycle: from calculations and analyses, through schematic design and collaboration on PCB design, to the construction and testing of prototypes.
You’ll work in a modern laboratory with a specialised workstation for evaluating MOSFET behaviour (8-channel oscilloscope, optically isolated probes with very high CMRR, specialised shunts), an EMC workstation and a climatic chamber.
The role will also involve streamlining development through automation, for example using Python and AI.
At a senior level, you may also get involved in research-focused topics, such as magnetics, EMC or the optimisation of converters with selected topologies, often in collaboration with industrial partners.
⭐ WE WOULD ALSO VALUE
Experience in the automotive sector or a similar environment, for example with relevant standards and processes, including ISO 26262.
Programming experience related to the creation of tools for hardware development, ideally in Python.
⚡ WHAT WE OFFER
A friendly, young and ambitious team, supported by experts from Czech and international R&D centres.
A modern laboratory and state-of-the-art equipment located directly within the office building, operational from 2024.
