We are seeking an experienced Radio Frequency (RF) Wireless Engineering Advisor with deep expertise in RF link budget analysis, wireless system performance, and end-to-end radio frequency engineering.

The successful candidate will serve as a senior technical authority responsible for developing, validating, and optimizing RF link budgets across wireless communication systems. This role requires the ability to translate system requirements into quantitative RF performance models, identify link-margin limitations, assess propagation and interference impacts, and provide engineering recommendations that support architecture, design, deployment, and operational decisions.

The Advisor will work across multidisciplinary engineering teams-including RF, antenna, systems, network, hardware, software, and field engineering-to ensure wireless systems achieve required coverage, capacity, availability, reliability, and performance objectives.

RF Link Budget Analysis
• Develop comprehensive uplink and downlink RF link budgets for terrestrial, satellite, cellular, private wireless, tactical, or other wireless communication systems.

• Calculate and validate key link-budget parameters, including:

  • Transmit power and EIRP

  • Receiver sensitivity

  • Antenna gain and losses

  • Cable, connector, feeder, and implementation losses

  • Free-space path loss

  • Atmospheric and environmental losses

  • Fading and shadowing margins

  • Polarization losses

  • Noise figure and system noise temperature

  • Thermal noise and noise bandwidth

  • Receiver G/T where applicable

  • Carrier-to-noise ratio (C/N)

  • Carrier-to-interference-plus-noise ratio (C/(I+N))

  • Eb/N and related digital link-performance metrics

  • Required and available link margin

• Develop link budgets for different frequency bands, modulation schemes, bandwidths, antenna configurations, propagation environments, and operating conditions.

• Perform best-case, nominal, worst-case, and statistical link-budget analyses.

• Establish appropriate engineering margins based on system availability and reliability requirements.

• Identify link-budget sensitivities and determine which parameters have the greatest impact on system performance.

• Perform trade studies involving transmit power, antenna gain, receiver performance, bandwidth, coding/modulation, frequency selection, and deployment configuration.

• TS/SCI with relevant Polygraph

• Minimum of 12 years with BS/BA; Minimum of 10 years with MS/MA; Minimum of 7 years with Ph.D.; an additional four years of experience may be considered in lieu of degree

• Demonstrated expert-level experience developing and reviewing RF link budgets.

• Strong understanding of RF propagation, antennas, transmission lines, receivers, transmitters, and wireless communication systems.

• Strong understanding of:

  • RF power and gain/loss calculations

  • dB/dBm/dBW conversions

  • Noise figure and noise temperature

  • Receiver sensitivity

  • C/N, C/I, C/(N+I), and Eb/N

  • Free-space and non-free-space path loss

  • Fade and implementation margins

  • Antenna gain, beamwidth, polarization, and pointing considerations

  • Modulation and coding impacts on RF performance

• Experience performing quantitative RF trade studies and sensitivity analyses.

• Ability to independently review and validate complex RF engineering analyses.

• Strong technical writing, presentation, and communication skills.

• Master's degree in Electrical Engineering, RF Engineering, Telecommunications, or a related discipline.

• Experience with 5G/4G, private LTE/5G, satellite communications, microwave, tactical communications, or other advanced wireless systems.

• Experience with RF propagation and coverage modeling tools.

• Experience with tools such as MATLAB/Simulink, Python, STK, ADS, HFSS, CST, Atoll, Pathloss, or comparable RF engineering software.

• Experience with RF test equipment, including spectrum analyzers, signal generators, network analyzers, power meters, and related instrumentation.

• Knowledge of antenna system design and characterization.

• Experience with link availability and reliability analysis.

• Familiarity with applicable IEEE, ITU, 3GPP, FCC, or other relevant RF/wireless standards and regulations.

• Experience supporting field deployment, drive testing, RF acceptance testing, or system verification.

• Experience leading technical teams or serving as a senior engineering consultant/advisor.
