Proxima Fusion is Europe's fastest-growing fusion company and the continent's best-funded fusion player, backed by over €650M. As a spin-out from the Max Planck Institute for Plasma Physics, the company is developing hardware and infrastructure for the world's first commercial stellarator fusion power plant. The team spans Munich, Zurich, and Oxford, combining stellarator optimization, advanced computation, machine learning, and high-temperature superconducting magnet technology.
In this role, you will design and develop PCB-based electronic circuits for converters that enable reliable and high-performance operation of fusion systems. You will translate functional requirements into robust electronic circuits, taking designs from initial concept and simulation through PCB implementation, laboratory testing, and integration into complete converter systems.
Key responsibilities include:
- Design and develop PCB-based electronic circuits for converters, including gate drivers, auxiliary power supplies, sensing, signal conditioning, protection, and DC-link balancing circuits
- Define circuit architectures, select components, perform simulations, and develop schematics and PCB designs according to functional, electrical, thermal, and reliability requirements
- Explore novel circuit topologies, component technologies, and integration concepts to improve converter performance, efficiency, reliability, compactness, and functionality
- Build prototypes and perform laboratory testing, characterization, verification, troubleshooting, and validation of electronic circuits and PCBs
- Collaborate closely with power electronics, embedded software, mechanical, thermal, and system engineers
Your work will directly influence the performance, reliability, safety, and maintainability of systems that power the world's first commercial stellarator fusion plant.
REQUIREMENTS:
- University degree in Electrical Engineering, Electronics Engineering, or related field
- Passion for PCB design from concept through simulation, prototyping to production qualification
- End-to-end ownership of electronic system design through multiple rapid iteration cycles
- Expert-level knowledge in analog and digital electronics, including sensing, signal conditioning, power supplies, isolation, gate drivers, and optical interface circuits
- Hardware-in-the-loop testing, automated test equipment, or laboratory test automation experience is a plus
