• Coordinate test schedules with certified external laboratories and manage customer test witnessing.
• Supervise testing at external laboratories while maintaining accurate, detailed activity logs. 

Required Skills 

• Test Equipment Proficiency: Expert level operating spectrum analyzers, EMI receivers, programmable power quality supplies, pin injection generators, data loggers, oscilloscopes, and digital multimeters (DMMs).
• EMI/EMC Principles: Deep technical understanding of conducted and radiated emissions, as well as RF susceptibility and immunity testing.
• RF & Coupling Hardware: Practical knowledge of EMI test antennas (rod, biconical, double-ridged horn, magnetic loop) and injection transformers used for conductive susceptibility testing.
• Test Chamber Setup: Proven ability to configure complex EMI and environmental test setups, including semi-anechoic chambers, thermal chambers, and vibration shakers.
• Automation Software: Familiarity with automated EMC test software suites (e.g., TILE, EMC32, or LabWindows/CVI) is highly desirable.
• Hardware Prototyping: Strong hands-on mechanical and electrical skills, including wire crimping, component soldering, and test fixture assembly. 

Qualifications and Education Requirements 

• Bachelor’s degree in Electrical Engineering (is a plus).
• Minimum of five years of related experience required.

Physical Requirements

• Prolonged periods sitting at a desk and working on a computer.
• Must be able to lift up to 15 pounds at times.
• Must be able to traverse production facility.
