We develop physics-based models, simulation environments, and analysis tools that help engineering teams evaluate system behavior, improve designs, and reduce risk before hardware design, integration, test, and fielding.\nAbout the Role:\nAs a Modeling & Simulation Engineer for Radars, you will develop, integrate, and validate models of radar and RFsensing systems. You will work across analytical, behavioral, measurement-level, signal/IQ-level, and closed-loop system models, selecting the fidelity appropriate to the design decision, software integration activity, test event, or verification objective. You will partner with radar architecture, RFand antenna, signal processing, tracking, embedded software, systems engineering, test, and product teams.\nExperience in every area below is not expected; candidates with depth in one or more relevant modeling and simulation domains are encouraged to apply.\nWhat You'll Do:\nDevelop, integrate, and maintain physics-based and performance-based models of radar and RFsensing systems.\n\nBuild models at appropriate levels of fidelity, including analytical radar-performance models, behavioral sensor models, measurement-generation models, signal or complex-IQmodels, radar-mode models, tracker models, and closed-loop system simulations.\n\nModel applicable radar effects such as antenna and beam patterns, beam steering, waveforms, RF-chain behavior, thermal noise, propagation loss, atmospheric effects, multipath, clutter, interference, jamming, target radar cross section, calibration errors, measurement biases, and uncertainty.\n\nDevelop or integrate applicable detection, thresholding, discrimination, measurement extraction, data-association, tracking, estimation, classification, sensor-fusion, radar-mode, and resource-management functions.\n\nBuild target, scene, geometry, trajectory, environmental, and threat models needed to evaluate radar performance in operationally relevant scenarios.\n\nPerform design trades, sensitivity studies, Monte Carlo analysis, uncertainty quantification, and design of experiments.\n\nCharacterize performance using metrics such as signal-to-noise or signal-to-interference-plus-noise ratio, probability of detection, false-alarm performance, coverage, detection range, measurement accuracy, track accuracy, revisit rate, update rate, latency, track capacity, and robustness to environmental or threat effects.\n\nIntegrate radar algorithms, radar software, embedded software, sensor models, target models, and hardware interfaces into SIL, SITL, HITL, HWIL, real-time, or large-scale batch simulation environments as applicable.\n\nValidate and correlate models against analytical references, laboratory and chamber measurements, calibration data, recorded signal or IQdata, radar-range data, field-test data, flight-test data, and other authoritative sources.\n\nDefine model requirements, interfaces, assumptions, limitations, validity domains, configuration controls, and acceptance or credibility criteria.\n\nDevelop and maintain simulation software, model APIs, scenario-generation tools, configuration systems, data pipelines, visualization tools, analysis workflows, and automated regression tests.\n\nSupport pre-test prediction, test planning, test-card or scenario development, test execution, anomaly investigation, and post-test analysis.\n\nProduce clear model documentation, validation evidence, performance reports, engineering-review material, and customer or program deliverables.\n\nRequired Qualifications:\nSignal- or complex-IQ-level radar simulation.\n\nRadar detection, measurement generation, discrimination, or signal processing\n\nRadar tracking, estimation, data association, or

data, or field or flight-test data.\n\nExperience analyzing large engineering data sets and communicating technically defensible conclusions.\n\nExperience with Git, code review, automated testing, issue tracking, continuous integration, and reproducible software or analysis workflows.\n\nAbility to work independently, make sound technical judgments, document assumptions and limitations clearly, and collaborate across engineering disciplines.\n\nActive Secret clearance.\n\nPreferred Qualifications:\nMaster’s degree or higher in electrical engineering, computer engineering, physics, applied mathematics, or a related field.\n\nExperience with AESAor phased-array radar, digital beamforming, electronically steered arrays, waveform design, adaptive processing, or cognitive radar.\n\nExperience in one or more radar mission areas, such as airborne surveillance, air-to-air radar, fire-control radar, ground-based air defense, missile warning, space surveillance, seeker radar, SAR, ISAR, GMTI, maritime surveillance, or counter-UAS.\n\nExperience with advanced detection, low-SNRprocessing, clutter suppression, Doppler processing, pulse compression, space-time adaptive processing, or electronic protection.\n\nExperience with Kalman filtering, nonlinear estimation, multi-target tracking, multi-hypothesis tracking, probabilistic data association, track management, or multisensor fusion.\n\nExperience modeling electronic attack, electronic support, interference, contested-spectrum environments, low-observable targets, or target-signature uncertainty.\n\nExperience
