- Communication: Fluent English is required for technical documentation and international collaboration.

## Preferred Qualifications

- Supply Chain Leadership: Direct experience working with vendors and manufacturers for high-volume production.

- High-Speed Design: Advanced understanding of Signal Integrity (SI) and Power Integrity (PI).

- Experience with S-parameters, PDN impedance modeling, and TDR measurements.

- System-Level Thinking: Ability to write or review embedded software (C/C++, STM32) to facilitate deep-level debugging and hardware-software co-design.

- Regulatory Mentorship: Experience guiding products through global certifications (UL, CE, RED), beyond basic compliance.

## Benefits
