Leidos’ NISC IV program seeks an Electrical Engineer (Spectrum Engineer) with specialized experience in Unmanned Aircraft Systems (UAS) to support the FAA Spectrum Engineering Services Group (AJW-19) at FAA Headquarters in Washington, DC.

The Spectrum Engineering Group is responsible for securing, managing, and protecting all civil aviation spectrum resources to ensure interference-free operation of FAA communications, navigation, and surveillance (CNS) systems across the National Airspace System (NAS). As Unmanned Aircraft System (UAS) operations expand, the FAA requires engineers who understand the unique RF characteristics, propagation considerations, and regulatory frameworks associated with UAS command-and-control (C2/CNPC), payload data links, airborne terminals, and ground-based systems.

Core Responsibilities:

• Contribute to the planning, coordination, and execution of FAA and non-FAA frequency assignment actions, ensuring that technical analyses and documentation conform to FAA Orders, the NTIA Manual (Redbook), and established engineering standards.
• Perform analyses to determine whether UAS frequencies introduce unacceptable interference to FAA communications, navigation, and surveillance systems.
• Identify potential UAS-related interference risks and propose technical mitigation.
• Conduct technical analyses for both airborne and ground-based UAS systems, including propagation modeling, link analyses, terrain impacts, signal power, and interference potential.
• Evaluate scenarios involving BVLOS operations, networked vs non-networked UAS systems, Airbourne transmitter impacts on aviation systems; and UAS terminals transmitting in shared or congested federal bands.
• Validate all technical data (location, equipment, parameters, emission designator, power, bandwidth, and antenna characteristics) for completeness and accuracy.
• Evaluate UAS operations in federal and non-federal bands following FAA, RTCA, ITU, and ICAO guidance.
• Assist in preparing technical input for domestic spectrum certification processes and international coordination activities.
• Support technical studies and spectrum planning efforts related to expanding UAS operations in national and international airspace.
• Support the FAA’s role in global harmonization efforts for UAS communications and non-payload spectrum use.

Basic Qualifications:

• Bachelor’s degree in electrical engineering, Electronics Engineering, Telecommunications Engineering, or equivalent technical field; completion of a formal spectrum management course or equivalent military experience in spectrum management (e.g., AFSC 3D1X4, MOS 25E) is also acceptable.
• 3 years of relevant experience in Unmanned Aircraft Systems (UAS) integration, spectrum engineering, or aviation systems planning.
• Understanding of UAS command-and-control links, airborne transmitter characteristics, line-of-sight propagation, and RF interference mechanisms.
• Experience conducting propagation modeling, link-budget analysis, and electromagnetic compatibility (EMC) studies.
• Ability to apply spectrum-engineering methodologies to novel or emerging UAS systems.
• Ability to learn FAA-specific software and systems.
• U.S. citizenship and active Secret (or higher) clearance required.

Preferred Qualifications:

• Knowledge of spectrum-engineering principles, electromagnetic theory, and radio-frequency propagation as applied to communications, navigation, and surveillance systems that support the National Airspace System (NAS).
• Understand the unique spectrum requirements for Unmanned Aircraft Systems (UAS), Urban Air Mobility (UAM), and Advanced Air Mobility (AAM).
• Familiar with NTIA Redbook, FAA Order 6050.32, ICAO/RTCA UAS Spectrum Standards, and FCC Part 87/Part 90/Part 95 rules.
• Familiar with Spectrum XXI or similar federal spectrum management tools is highly desirable.

If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo — because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 — and moving faster than anyone else dares.
