Senior Electrical EngineerRadio Frequency (RF) Engineer

Leidos NISC IV program seeks an Electrical Engineer/Radio Frequency (RF) Engineer to support the Federal Aviation Administration (FAA) Spectrum Engineering Services Group. 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). The candidate will be responsible for supporting the investigation analysis and resolution of radio frequency (RF) interference affecting critical communications navigation and surveillance systems. The ideal candidate will have strong experience in RF spectrum analysis interference mitigation radio direction finding and field investigations using industry-standard test equipment.

Primary Responsibilities

RF Interference Investigation

• Investigate reports of radio frequency interference (RFI) affecting mission-critical communications navigation surveillance or wireless systems.
• Perform both on-site and remote RF interference investigations to identify characterize and resolve interference sources.
• Conduct root-cause analysis of intermittent and persistent RF interference events.
• Document findings recommend corrective actions and verify successful mitigation of interference issues.

Spectrum Analysis

• Operate spectrum analyzers monitoring receivers and related RF test equipment to identify interfering emissions.
  • Measure and analyze:
  • Frequency
  • Bandwidth
  • Occupied spectrum
  • Modulation characteristics
  • Power levels
  • Harmonics
  • Spurious emissions
• Evaluate RF propagation characteristics signal strength noise floor and overall spectrum utilization.
• Interpret RF measurements and prepare technical reports for engineering and operational stakeholders.

Radio Direction Finding (RDF)

• Perform radio direction finding (RDF/DF) operations to locate unknown RF interference sources.
• Utilize directional antennas GPS mapping and triangulation techniques during field investigations.
• Conduct drive testing and field measurements to accurately pinpoint interference locations.
• Support rapid response activities for high-priority interference events.

Required Qualifications

• Bachelors degree in Electrical Engineering Telecommunications Computer Engineering or a related technical field (or equivalent experience).
• Minimum 8 years of experience in RF engineering spectrum management interference mitigation or wireless communications.
• Experience conducting RF interference investigations and root-cause analysis.
• Proficiency using RF test equipment including:
  • Spectrum analyzers
  • Monitoring receivers
  • Signal generators
  • RF power meters
• Experience with radio direction finding equipment and techniques.
• Understanding of RF propagation antenna theory modulation methods and electromagnetic interference (EMI).
• Ability to analyze technical data and prepare detailed engineering reports.
• Strong troubleshooting and analytical skills.
• Willingness to travel for field investigations as required.
• Excellent troubleshooting and problem-solving abilities.
• Strong written and verbal communication skills.
• Ability to work independently and collaboratively in field and office environments.
• Experience working in fast-paced operational environments.
• Strong attention to detail and commitment to technical excellence.
• Valid drivers license.
• Must be a US citizen.

Preferred Qualifications

• Experience supporting aviation public safety defense telecommunications or government communications systems.
• Familiarity with FCC NTIA or international spectrum regulations.
• Experience with spectrum monitoring software and GIS/GPS mapping applications.
• Knowledge of digital communication systems microwave satellite LTE/5G or land mobile radio (LMR) technologies.
• Security clearance or ability to obtain one (if applicable).
