• Key tasks include supporting and/or leading in-house testing and local field testing of electromagnetic field propagation, antenna characterization and communication link performance. The role requires excellent communication skills and ability to effectively collaborate with multidisciplinary groups, including software and hardware engineering.

Responsibilities

• Provide expert level system test and troubleshooting using signal generators, vector network analyzers, signal analyzers, E-field and B-field sensors
• Integration and test of passive LF/HF high power, standard and electrically small antennas as well as optimization of associated matching networks
• Anechoic chamber testing
• Support and/or lead engineering teams for in-house and local field testing of electromagnetic field propagation, antenna and communication link performance
• Drive solutions to complex problems with limited direction – contribute to requirements development, propose ways forward, and adapt appropriately to changes in requirements
• Perform analysis and modeling of RF hardware, provide insight and suggest design modifications based on analysis
• Identify program/system-level technical risks and develop and execute mitigation strategies
• Actively mentor less experienced engineers and provide thoughtful, constructive feedback

Requirements

• Extensive experience utilizing ferrite beads, RF chokes and baluns in radio and antenna systems
• Experienced with capacitive and inductive coupling
