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 desirable but not required.\nThis is a hybrid position requiring regular on-site presence 3 days in Washington, D.C. to access a Sensitive Compartmented Information Facility (SCIF) to perform work involving classified information and 2 days remote work.\nCore Responsibilities:\nConduct 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.\nEvaluate 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.\nAssess 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.\nPrepare and process Special Temporary Authorization (STA) requests using the Automatic Frequency Manager system to support temporary C-UAS spectrum operations.\nUtilize 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.\nPrepare 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.\nBasic Qualifications:\nBachelor’s degree in electrical engineering or closely related technical discipline.\n1+ years of relevant experience in RF/spectrum engineering, EMI/EMC and interference analysis, RF propagation/modeling, geospatial analysis, frequency coordination, or spectrum management.\nExperience or knowledge on reviewing and interpreting RF technical specifications and engineering data, including frequencies, bandwidths, power levels, antenna and emission characteristics, receiver characteristics, and geographic operating parameters.\nAbility 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.\nExperience using RF/spectrum engineering, modeling and simulation, propagation analysis, GIS/geospatial, or other technical analysis tools.\nStrong analytical and problem-solving skills with the ability to evaluate complex technical information and develop technically supportable recommendations.\nStrong written and verbal communication skills with the ability to communicate technical information to engineering, program management, government, and other stakeholders.\nMust be a U.S. citizenship and possess and maintain a DoD Secret security clearance or able to obtain and maintain a DoD Secret clearance.\nPreferred but Not Required:\nExperience with RF spectrum management, spectrum compatibility analysis, frequency assignment/coordination, or spectrum certification in a federal government, military, aviation, telecommunications, or similar environment.\nKnowledge or experience with Counter-Unmanned Aircraft Systems (C-UAS), Unmanned Aircraft Systems (UAS), electronic warfare, radar, RF detection systems, or RF-based mitigation technologies.\nFamiliarity with FAA National Airspace System (NAS) infrastructure and Communications, Navigation, and Surveillance (CNS) systems.\nKnowledge of federal spectrum management regulations, policies, and processes, including NTIA and FCC requirements, the NTIA Manual and frequency assignment and protection practices.\nExperience 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.\nExperience using aeronautical charts, GIS, or other geospatial information to evaluate potential RF, operational, or aviation impacts.\nIf you're looking for comfort, keep scrolling.
