Principal MVDC Circuit Breaker Engineer

Nuremberg

We’re looking for an experienced Principal Engineer to lead the development of next-generation medium-voltage DC (MVDC) circuit breaker technology.

This is an opportunity to work at the forefront of power electronics, protection systems and high-voltage engineering — combining advanced simulation, hands‑on prototyping, laboratory testing and collaborative research to solve some of the most challenging problems in modern electrical networks.

What you’ll be doing

Lead the design, simulation and testing of MV circuit breakers across vacuum, solid‑state and hybrid technologies, with a particular focus on ultrafast MVDC interruption and next‑generation protection architectures.

Push actuator technology further

Design, model and optimise coil actuators, balancing speed, electromagnetic performance, reliability and practical implementation.

Turn concepts into working technology

Develop MV/MVDC test circuits, build prototypes and lead high‑voltage laboratory testing. Use simulation and experimental data to validate performance and drive continuous improvement.

Work with universities, research organisations and technology partners on advanced topics including smart grids, fault protection and high‑speed switching. Help translate research into publications, patents and real‑world technology.

Shape the technology roadmap

Explore new approaches to MVDC interruption, fault mitigation and protection — while ensuring designs meet relevant IEC/IEEE standards.

What you’ll bring

We’re looking for someone with deep technical expertise and a genuine passion for solving complex power‑system challenges.

You’ll ideally have:

• 5+ years’ hands‑on experience in MV/HVDC protection, circuit breaker development, fault analysis and interruption technologies.
• Strong knowledge of hybrid circuit breakers, ultrafast protection, MVDC breakers and innovative interrupter technologies.
• Experience with DER integration, including PV and BESS applications.
• Expertise in electromagnetic and thermal modelling for high‑power applications.
• Experience with real‑time simulation and/or FPGA‑based control systems.
• Knowledge of vacuum or gaseous circuit breaker technologies is advantageous.
• A track record of research, publications or collaboration with universities/research institutions in MV protection or related fields.
• Experience providing technical leadership within circuit breaker development or other complex engineering programmes.
• A creative, analytical mindset and the ability to turn challenging technical problems into practical solutions.
