RF Electrical Engineer

Job Description The Leidos Defense Space Business Area is seeking an RF Electrical Engineer to support the Emerging Space Systems Division in the development of advanced RF technologies for next‑generation space missions. Responsibilities Support the design, modeling, and experimental validation of electromagnetic technologies operating across the radio frequency spectrum. Contribute to RF antenna modeling and performance analysis, assist with design trades and system‑level evaluations based on laboratory measurements, and support the development of compact, high‑performance payloads. Play a hands‑on role in laboratory activities, including prototype antenna characterization, electronics integration, testing, and characterization of components and systems. Work closely with senior engineers and cross‑functional teams to evaluate and mature emerging RF technologies such as RF metamaterials and electrically small antennas, analyze experimental data to inform design decisions, and document results to support internal R&D and program efforts. Balance analytical and experimental work; be comfortable working across simulation and laboratory environments and be motivated to grow technical expertise in both domains. Basic Qualifications Bachelor’s Degree in Engineering, Physics, or a related field with 8+ years of prior relevant experience, or a Master’s Degree with 6+ years of prior relevant experience. May possess a Doctorate in the technical domain. US citizenship with the ability to obtain and maintain a Secret security clearance. Experience with RF antenna modeling, simulation, or analysis. Familiarity with RF aperture performance metrics such as Rx/Tx antenna gain, effective isotropic radiated power (EIRP), radiation efficiency, noise characteristics. Experience working in a laboratory environment, including anechoic chamber testing or characterization. Strong analytical and problem‑solving skills with attention to detail. Effective communication skills and ability to work in a collaborative team environment. Preferred Qualifications Active Secret clearance with ability to obtain a higher‑level clearance (TS/SCI). Hands‑on experience with building RF testbeds for characterizing RF technologies. Experience with antenna design tools such as COMSOL, CST Microwave Studio, or equivalent. Exposure to advanced RF technologies such as RF metamaterial antennas, space‑time modulation, or electrically small antennas. Pay and Benefits Pay Range: $107,900.00 – $195,050.00. Benefits include competitive compensation, Health and Wellness programs, Income Protection, Paid Leave and Retirement.
