RF Electrical Engineer

RF Electrical Engineer – Emerging Space Systems Division

The Leidos Defense Space Business Area is seeking a RF Electrical Engineer to support the development of advanced RF technologies for next-generation space missions.

• Design, model and experimentally validate electromagnetic technologies operating across the radio frequency spectrum.
• Perform RF antenna modeling and performance analysis, assist with design trades and system-level evaluations based on laboratory measurements.
• Support the development of compact, high-performance payloads.
• Conduct laboratory activities including prototype antenna characterization, electronics integration, testing, and characterization of components and systems.
• Collaborate 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 in simulation and laboratory environments, and grow technical expertise in both domains.

• 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.

• 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.
