Principal Engineer - High-Speed Test Instrument Hardware Development Engineer

As Principal Engineer in Munich, you will advance microwave photonics hardware for 224G test and measurement instruments. You will own circuit design, simulation, and debugging of RF/microwave blocks and integrate with analog front-ends. You’ll drive component selection, schematic/PCB design, and lab measurement to optimize complete microwave systems. You will collaborate across teams, document designs, and stay at the forefront of RF/optical instrumentation and tech trends.
