Job description

Leidos’ NISC IV program is seeking a Radio Frequency (RF) Engineer/Spectrum Engineer to support the FAA Spectrum Engineering Services Group (AJW-194) in the area of National Defense and Electronic Attack. The ideal candidate will have experience in RF/spectrum engineering, EMI/EMC and interference analysis, RF propagation/modeling, and/or geospatial analysis. The engineer will provide technical engineering and spectrum management support to evaluate Counter-Unmanned Aircraft System (C-UAS) test, training, and operational activities for potential impacts to the National Airspace System (NAS). Prior C-UAS experience is highly desirable but not required. This is a hybrid position requiring regular on-site presence in Washington DC to access a Sensitive Compartmented Information Facility (SCIF) and perform work involving classified information.

Core Responsibilities

• Conduct RF spectrum compatibility and interference analyses of C-UAS detection and mitigation systems, including frequency deconfliction, RF propagation, and geospatial analysis, to identify potential impacts to FAA and National Airspace System (NAS) communications, navigation, surveillance, and other safety-critical systems.
• Evaluate C-UAS test, training, and operational requests submitted by FAA and interagency partners, review technical parameters for completeness, determine required engineering analyses, and provide technical support for FAA C-UAS testing and evaluation activities.
• Assess NAS impacts and develop mitigation recommendations using RF modeling and simulation tools, spectrum databases, geographic information, aeronautical charts, and other engineering data.
• Identify appropriate technical controls such as frequency, power, geographic, or operational restrictions necessary to protect FAA/NAS systems.
• Prepare and process Special Temporary Authorization (STA) requests using the Automatic Frequency Manager system to support temporary C-UAS spectrum operations.
• Utilize RF spectrum engineering tools and databases, including the Technical Compatibility and Analysis Tool (TCAT) and Government Master File (GMF), to perform circle searches, transmitter/receiver analyses, Desired-to-Undesired (D/U) signal ratio calculations, and other RF compatibility assessments.
• Prepare technical reports, white papers, briefings, and engineering documentation communicating analysis results, spectrum impacts, mitigation recommendations, and other technical information to technical and non-technical stakeholders.

Basic Qualifications

• Bachelor’s degree in electrical engineering or related technical discipline, completion of a formal spectrum management course, or equivalent military education and experience.
• 2+ years of relevant experience in RF/spectrum engineering, EMI/EMC and interference analysis, RF propagation/modeling, geospatial analysis, frequency coordination, or spectrum management.
• Experience reviewing and interpreting RF technical specifications and engineering data, including frequencies, bandwidths, power levels, antenna and emission characteristics, receiver characteristics, and geographic operating parameters.
• Ability to perform technical analysis to identify potential RF interference, spectrum compatibility, or frequency deconfliction issues between systems operating within the same or adjacent frequency bands.
• Experience using RF/spectrum engineering, modeling and simulation, propagation analysis, GIS/geospatial, or other technical analysis tools.
• Strong analytical and problem-solving skills with the ability to evaluate complex technical information and develop technically supportable recommendations.
• Strong written and verbal communication skills with the ability to communicate technical information to engineering, program management, government, and other stakeholders.
• Must be a U.S. citizenship and possess and maintain a DoD Secret security clearance or able to obtain and maintain a DoD Secret clearance.

Preferred but Not Required

• Experience with RF spectrum management, spectrum compatibility analysis, frequency assignment/coordination, or spectrum certification in a federal government, military, aviation, telecommunications, or similar environment.
• Knowledge or experience with Counter-Unmanned Aircraft Systems (C-UAS), Unmanned Aircraft Systems (UAS), electronic warfare, radar, RF detection systems, or RF-based mitigation technologies.
• Familiarity with FAA National Airspace System (NAS) infrastructure and Communications, Navigation, and Surveillance (CNS) systems.
• Knowledge of federal spectrum management regulations, policies, and processes, including NTIA and FCC requirements, the NTIA Manual and frequency assignment and protection practices.
• Experience reviewing spectrum certification and equipment allocation documentation, including DD Form 1494, Joint Frequency Allocation (J/F-12) documentation, Spectrum Reports, or similar RF technical documentation.
• Experience using federal spectrum management databases or systems such as the Government Master File (GMF), Automatic Frequency Manager (AFM), or similar frequency management databases and tools.
• Experience using aeronautical charts, GIS, or other geospatial information to evaluate potential RF, operational, or aviation impacts.
• Experience coordinating spectrum or technical matters with federal agencies and interagency organizations, such as the FAA, NTIA, FCC, DoD, DHS, DOJ, or the Interdepartmental Radio Advisory Committee (IRAC).
• Experience preparing Special Temporary Authorization (STA) requests or other temporary frequency authorization/coordination documentation.
