Principal RF Engineer

Article2 minutes readSharePhysical Sciences Inc., an employee-owned company, located 25 miles north of Boston in Andover MA, is seeking an experienced and motivated Principal RF Engineer to support the research, development, and deployment of cutting-edge technologies including directed energy systems, novel microwave phase shifters, deployable phased array space antennas, and hypersonic antennas. A solid understanding of theoretical concepts and first principles is a must, as well as the ability to work independently. The ideal candidate will be multi-disciplinary, with strong abilities in systems engineering.The candidate will help design and build advanced RF systems including:Broadband and narrowband antenna systemsHigh temperature phased array antennasPhase shifters and lightweight transmission linesNovel RF sourcesFully integrated counter-electronic directed energy systemsApplications include counter-unmanned aerial systems (C-UAS) and vehicle/vessel engine stopping technologies, as well as high temperature antennas for missiles and hypersonic vehicles. The role offers a hands-on opportunity to work on real-world, field-deployable systems across all development phases, from early R&D through product development.What You’ll DoDesign, prototype, and maintain RF test platformsSimulate and develop novel antenna and transmission line architecturesCollaborate with mechanical engineers on design for manufacturing antennas and RF componentsSupport integration of RF sources and pulsed power systems into HPM prototypesConduct and interpret anechoic chamber and free-space measurementsAssist system engineers and business development teams in generating new technical proposals and system conceptsLead and mentor junior engineers while managing multi-disciplinary technical effortsRequired QualificationsBachelor’s degree in Electrical Engineering, Physics, or related field (MS or PhD strongly preferred)At least 6 years of hands-on experience in RF system design, test, and integrationHighly proficient in using RF test equipment: VNAs, spectrum analyzers, oscilloscopes, signal generators, and power metersDeep understanding of RF theory and first principles, including components like circulators, amplifiers, mixers, phase shifters and phased-array antennasStrong communication and documentation skillsDemonstrated ability to work independently and across engineering disciplinesPreferred Skills & ExperienceExperience with antenna and transmission line fabrication techniques as well as antenna characterizationFamiliarity with RF data acquisition and post-processing toolsExperience measuring the complex permittivity of solid and liquid dielectric materialsMagnetic circuit design and knowledge of ferrimagnetic materialsMechanical prototyping and lab system assembly experience (cooling systems, enclosures, electronics)Proficiency in RF simulation tools such as CST Microwave Studio, HFSS, or COMSOLPCB design and layout experience (e.g. Altium)U.S. Citizenship Is Required.All qualified applicants will receive consideration for employment without regard to their race,color, religion, sex, sexual orientation, gender identity, national origin, disability, or status as aprotected veteran
