SIMULIA Spark3D is a simulation tool for determining the Radiofrequency (RF) breakdown power level in a wide variety of passive devices, including cavities, waveguides, microstrip and antennas. It imports electromagnetic field monitors from CST Microwave Studio to analyze vacuum breakdown (multipactor) and gas discharge. Spark3D calculates the maximum power that the device can handle without causing discharge effects.

Position based in Valence (Spain) - Temporary contract - 6 months

Your missions :
Spark3D performs full numerical simulations of the multipactor effect considering the 3D EM field distribution. To perform this simulation, Spark3D emits electrons in the component, tracking their trajectories and checking the evolution of the electron number with time.

Spark3D performs full numerical simulations of gas discharge considering the 3D EM field distribution. Spark3D solves the free electron continuity equation in the component, checking if the electron density grows with time for a particular input power level. With this, users can calculate their devices' breakdown voltage and power level.

The job position will consist on collaborating in the maintenance and enhancement of Spark3D user interface and back-end.

Your qualifications :
Master’s degree in Physics or Electrical/Telecommunication Engineering with 1–3 years of relevant experience.

Solid knowledge of electromagnetism, numerical methods for electromagnetic simulation, and C++/Qt programming.
Strong team player with effective communication skills, able to collaborate in multidisciplinary R&D environments, manage priorities efficiently, contribute to software performance improvements, and support knowledge sharing initiatives.
