RF Modeling and Simulation Engineer - Levels

Regular

AV is seeking Mid-level to Senior-level RF Modeling and Simulation Engineers to work onsite at our Albuquerque, New Mexico or Germantown, Maryland offices
. These positions support the analysis, development, integration, verification, and production of advanced RF, phased-array, aerospace, and electromechanical systems.

RF Modeling and Simulation Engineers at AV develop system-level models and analysis tools that guide architecture, design, performance prediction, test planning, and production decisions. The ideal candidate has experience with RF system modeling, phased-array analysis, electromagnetic simulation, and correlation of analytical results with measured data.

You will collaborate with RF, digital hardware, antenna, PCB layout, mechanical, thermal, manufacturing, assembly, systems, and test teams throughout the product lifecycle—from early architecture and design trades through verification, qualification, production, and field support. Senior-level engineers may lead modeling activities, establish analysis methods, mentor engineers, and provide technical direction.

• Develop RF system, antenna, and phased-array models covering propagation, element behavior, beamforming, RF distribution, amplification, frequency conversion, digitization, and system interfaces.
• Analyze performance metrics such as gain, loss, noise figure, EIRP, scan loss, beam patterns, sidelobes, phase and amplitude error, dynamic range, and link margin.
• Evaluate the effects of component tolerances, calibration residuals, thermal drift, mutual coupling, packaging, layout, and assembly variation.
• Use MATLAB, HFSS, ADS, CST, Python, or comparable tools to develop reusable models, simulation workflows, automated analyses, and technical visualizations.
• Define and document model assumptions, interfaces, parameters, units, limitations, and validity ranges.
• Automate parameter sweeps, uncertainty studies, sensitivity analyses, optimization, and design trade studies.
• Correlate model predictions with measured data from RF boards, phased-array tiles, subsystems, antenna ranges, chambers, and production testing.
• Work with design and test engineers to investigate model-to-measurement differences, identify physical causes, and update models using controlled evidence.
• Provide performance margins, sensitivity results, and recommendations for architecture, component selection, PCB layout, calibration, packaging, and assembly decisions.
• Support requirements development, verification planning, test definition, and technical closure through analysis and measurable predictions.
• Participate in design, test-readiness, production-readiness, and customer technical reviews.
• Maintain configuration-controlled records of model inputs, outputs, revisions, configurations, and correlation results.
• Lead technical tasks, modeling efforts, special projects, or process improvements based on experience.
• Mentor junior and mid-level engineers and promote reusable, traceable, and disciplined modeling practices.
• Support occasional travel to customer, supplier, test, or field locations as required.

• Bachelor’s or master’s degree in Electrical Engineering, RF Engineering, Applied Physics, or a related technical discipline.
• Mid-Level: Typically five or more years of relevant experience in RF modeling, electromagnetic simulation, array analysis, RF system development, or related hardware development.
• Senior-Level: Typically eight or more years of relevant experience, including demonstrated technical leadership in RF modeling, simulation, or system analysis.
• Strong understanding of RF systems, phased-array architecture, beamforming, antennas, RF front ends, propagation, mixed-signal interfaces, and measurement correlation.
• Advanced MATLAB experience and working proficiency with at least one additional tool, such as HFSS, ADS, CST, Python, or a comparable RF simulation environment.
• Ability to define engineering assumptions, quantify sensitivity and uncertainty, and communicate model limitations clearly.
• Experience applying analysis results to design decisions, requirements evidence, test planning, or technical recommendations.
• Strong analytical, technical writing, visualization, communication, and presentation skills.
• Ability to work effectively across multidisciplinary engineering teams.
• Must be a U.S. citizen.
• Ability to obtain and maintain a U.S. security clearance, if required by the program.
