Power Electronics Engineer

Title: Power Electronics Engineer

Reports to: Principal Power Electronics Engineer (Team Lead)

Based at: Newport

Contract Type: Permanent – Full time

Job purpose:

Here at Compound Semiconductor Applications (CSA) Catapult we are focused on bringing compound semiconductor applications to life in three key areas: the road to Net Zero, future telecoms and intelligent sensing.

We are a Not for Profit organisation based in South Wales.  We focus on three technology areas: Power Electronics, RF & Microwave and Photonics and have an Advanced Packaging team for these high-power innovations.

This is an excellent opportunity to take the next step in your Power Electronics career and be part of a small, friendly and progressive and experienced  team working on cutting edge technology. We are passionate about internal development with ongoing training opportunities both internally and externally to help you learn new skills and reinforce existing ones.

Our Engineers have different focuses and we have outlined the 2 key specialisms that we would be looking for. If you have the experience specified in any one of the below roles please send in your CV indicating which you are applying for. 


Electrical Engineer specialist in Electromagnetic Modelling & Simulations

  • Numerical modelling (Finite Element, Method of Moments) and optimization of electromagnetic and semiconductor devices and PCBs.
  • Electric circuits simulation (Pspice, SABER, SIMetrix).
  • Extensive knowledge of the following modelling tools: ANSYS ELECTRONICS DESKTOP, SIwave, COMSOL MULTIPHYSICS, SolidWorks, MATLAB.
  • Experience in designing magnetic components for power electronics converters.
  • Experience in performing magnetic field measurements (Hall Probe, rotating coils).
  • Experience in operating B-H Analysers and Impedance Analysers /Frequency Response Analysers.
  • Experience in modelling multi-physics coupled problems such as thermal and electromagnetic modelling of semiconductor devices.



Power Electronics Engineer specialist in Thermal Reliability & Thermal Characterization of Semiconductor Devices
