Minimum Qualifications:

• Proficiency in wireless technologies, specifically Wi-Fi and Bluetooth standards.
• Intermediate experience with Python and MATLAB for scripting and system characterization tasks.
• Basic familiarity with RF measurement equipment and techniques for setting up lab test stations for wireless systems and testing signal strength and power consumption.
• Ability to develop and execute test plans, focusing on the integration and characterization of wireless systems.
• Experience with measuring and analyzing key performance metrics such as throughput (under different data traffic profiles), signal strength (RSSI, SNR), and power consumption.
• Ability to setup end-to-end wireless characterization stations, and addressing basic issues at RF level, wireless system/drivers, and OS/application running over the wireless links.

Preferred Qualifications:

• Previous experience with wireless system characterization in a development and testing environment.
• Familiarity with power consumption measurement techniques for varied wireless link use cases.
• Experience in executing on-body link quality measurements and interpreting the data for product development.
• Strong ability to innovate in scripting and automation processes to enhance testing efficiency.
