Job Title : Senior RF & Electromagnetics Engineer
Location : Guilford, CT, USA
The Senior RF & Electromagnetics Engineer, designs, tests, characterizes, and optimizes RF coils and associated analog electronics for the low MHz frequency domain. Secondary to this, they may contribute significantly to the electromagnetic subsystem of the ultra low field MRI system, including B0 magnet and gradient system. They develop manufacturing and design verification processes to ensure manufactured products meet design goals with efficiency and cost-effectiveness. The senior engineer is expected to be able to conduct research and development activities independently when needed, collaborate cross-functionally, and provide guidance to junior engineers.
Key Responsibilities
Conduct research and development efforts related to radiofrequency coils, sensors, preamplifiers, and analog circuitry for portable MRI applications.
Simulate, test, and optimize coil and RF electronics designs.
Collaborate cross-functionally with systems engineers, mechanical engineers, electrical engineers, and MR scientists, product management and senior leadership to ensure seamless integration of RF and electromagnetic subsystems.
Develop and validate novel hardware-based EM-noise reduction methods for ultra-low-field MRI.
Partner with vendors and manufacturing teams to guide electromagnetic system prototyping, assembly, production scale-up and QA processes.
Document designs, models, and tools in accordance with the company’s quality system requirements.
Additional Responsibilities:
Contribute to research and development efforts related to low-field magnet, gradient coil, and shield design for portable MRI applications.
Develop and validate novel magnet characterization methods, including field mapping, eddy-current mapping and thermal stability assessments.
