Power Electronics Test Engineer — Lead System-Level Validation

Lightyear; Venray; On-site; EUR 55,000 - 90,000; Full time

Benefits offered by this job

Pension scheme

40 vacation days per year

Job summary

Lightyear is developing a family of power converters to convert solar energy from PV panels on vehicles to their batteries. The converter range consists of LV variants, HV variants and a multi-port variant that is able to convert energy from multiple solar panels to both LV and HV batteries.

By intelligently combining several functions, this topology allows for a reduction in component count and improvement in efficiency.

Qualifications

• Bachelor’s in Electronics Engineering or similar.
• Knowledge of power electronics fundamentals.
• Experience with hardware debugging and instrumentation.
• Experience with PCB and system level troubleshooting.
• Experience with embedded software (C, C++ or Rust) debugging.
• Experience with electronics certification (ISO 16750, CISPR25, R10) is a plus.
• Scripting/automation.
• Basic understanding of control systems, preferably in the context of power electronics, motor drives, battery systems, or similar dynamic systems.
• Ability to interpret control‑related converter behavior such as stability, transient response, tracking performance, protection behavior, and interaction with hardware limits.
• Able to act as a technical bridge between hardware, embedded software, and control engineering during test definition, debugging, and issue resolution.
• Experience with model‑based development, control tuning, or MATLAB/Simulink is a big plus

Responsibilities

• Design and build custom test setups that simulate demanding real-world conditions.
• Write robust automation software to streamline data acquisition.
• Perform in-depth tests to characterize system behavior, including efficiency, tracking performance, EMC, transient behavior, and control-related dynamics.
• Investigate anomalies, identify root causes, and coordinate with domain experts to implement lasting solutions.
• Develop test automation software for end‑of‑line testing.
