Cox & Company solves the aerospace industry's most challenging ice protection and temperature control problems.  For over 80 years Cox has worked with OEMs, Tier 1 and Tier 2 Suppliers, as well as all major modification and finishing centers throughout the world. From initial design concepts through aircraft integration and operation, our company provides the highest quality full-lifecycle support to our customers.  

Cox & Company, Inc. is seeking a Test Engineer with comprehensive knowledge of aerospace industry testing standards to lead product qualification efforts. The ideal candidate will be responsible for developing formal test engineering procedures and coordinating and conducting qualification tests at certified external laboratories. Technical expertise must span electromagnetic interference (EMI) testing, including radiated and conducted emissions, susceptibility, and pin injection, as well as electrical power quality, transients, and environmental testing such as temperature, shock, and vibration.  

Role and Responsibilities 

• Develop detailed test plans and procedures in accordance with RTCA DO-160, MIL-STD-810, MIL-STD-704, and MIL-STD-461 requirements.
• Define and specify necessary support equipment, including wiring harnesses, electrical interfaces, vibration fixtures, instrumentation, and test setup diagrams.
• Plan, conduct, and evaluate internal risk-reduction tests at Cox and Company.
• Collect, analyze, and organize testing data to generate comprehensive Qualification Test Reports for customers and management.
• Provide regular testing status updates to Engineering Managers and Program Managers.
• 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.
