Power Electronics Engineer

About the role

Proxima Fusion is developing the world’s first commercial stellarator fusion power plant. The Power Electronics Engineer will design and integrate high‑performance power conversion solutions that meet demanding efficiency, reliability and thermal requirements.

Key responsibilities

• Evaluate and develop power‑conversion topologies, considering efficiency, electrical stresses, thermal behaviour and power density.
• Design magnetic components (inductors, transformers, chokes) and select appropriate materials, core geometries and winding concepts.
• Create analytical and simulation models to predict converter performance, semiconductor stresses and losses.
• Build prototypes, conduct laboratory testing, characterization, troubleshooting and validation of power‑electronic circuits.
• Analyse test results, correlate measurements with simulations and propose design improvements.

Required profile

• University degree in Electrical Engineering, Power Electronics or a related field.
• Proven experience taking power‑stage designs from concept through simulation, prototype, testing and validation.
• Strong knowledge of power conversion topologies, power semiconductors and magnetic components.

Required skills

• Power conversion topologies
• Power semiconductors (SiC, GaN)
• Magnetic component design
• Electro‑thermal simulation tools (e.g., PLECS)
• High‑frequency magnetics
