What you will do

• Develop, integrate, maintain, and validate physics-based and performance-based models for radar and RF sensing systems across analytical, behavioral, measurement, signal/IQ, radar-mode, tracker, and closed-loop system levels.
• Model radar effects including antenna and beam patterns, beam steering, waveforms, RF-chain behavior, noise, propagation, atmospheric effects, multipath, clutter, interference, jamming, radar cross section, calibration errors, biases, and uncertainty.
• Develop or integrate detection, thresholding, discrimination, measurement extraction, data association, tracking, estimation, classification, sensor-fusion, radar-mode, and resource-management functions.
• Build target, scene, geometry, trajectory, environmental, and threat models; perform design trades, sensitivity studies, Monte Carlo analysis, uncertainty quantification, and design of experiments.
• Integrate radar algorithms, radar and embedded software, sensor and target models, and hardware interfaces into SIL, SITL, HITL, HWIL, real-time, and batch simulation environments.
• Validate models against analytical references, measurements, recorded signal or IQ data, range data, field tests, and flight tests; support test planning, execution, anomaly investigation, post-test analysis, documentation, and customer or program deliverables.

Requirements

• Experience with signal- or complex-IQ-level radar simulation.
• Experience with radar detection, measurement generation, discrimination, or signal processing.
• Experience with radar tracking, estimation, data association, or sensor fusion.
• Experience with radar modes, resource management, or system-performance analysis.
• Experience with RF propagation, clutter, interference, electronic warfare, or electronic protection.
• Experience with real-time radar stimulation, HITL, or HWIL.
• Strong programming ability in at least one scientific or analytical environment such as MATLAB, Python, or C++.
• Experience with Monte Carlo simulation, sensitivity analysis, statistical analysis, uncertainty modeling, or design of experiments.
• Experience validating or correlating models against analytical results, laboratory measurements, recorded sensor data, range data, or field or flight-test data.
• Experience analyzing large engineering datasets and communicating technically defensible conclusions.
• Experience with Git, code review, automated testing, issue tracking, continuous integration, and reproducible software or analysis workflows.
• Ability to work independently, make sound technical judgments, document assumptions and limitations clearly, and collaborate across engineering disciplines.
• Active Secret clearance.

Nice to have

• Master’s degree or higher in electrical engineering, computer engineering, physics, applied mathematics, or a related field.
• Experience with AESA or phased-array radar, digital beamforming, electronically steered arrays, waveform design, adaptive processing, or cognitive radar.
• Experience in 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.
• Experience with advanced detection, low-SNR processing, clutter suppression, Doppler processing, pulse compression, space-time adaptive processing, or electronic protection.
• Experience with Kalman filtering, nonlinear estimation, multi-target tracking, multi-hypothesis tracking, probabilistic data association, track management, or multisensor fusion.
• Experience modeling electronic attack, electronic support, interference, contested-spectrum environments, low-observable targets, or target-signature uncertainty.
• Experience with antenna-pattern data, radar cross-section data, computational-electromagnetics outputs, or RF-system calibration data.
• Experience with GPU acceleration, CUDA, HPC, deterministic real-time systems, FPGA or SDR interfaces, radar stimulators, or high-throughput batch execution.
• Experience integrating embedded radar or tactical software into closed-loop simulations.
• Experience with requirements traceability, MBSE, model-based development, formal model V&V, simulation-credibility assessments, or verification evidence.
• Experience with distributed simulation frameworks such as DIS, HLA, TENA, or similar technologies.
• Experience supporting DoD, intelligence-community, missile-defense, DARPA, AFRL, ONR, MDA, NAVAIR, DEVCOM, advanced aerospace, or advanced commercial technology programs.
• Experience building simulation APIs, scenario-generation tools, configuration systems, data pipelines, analysis tooling, visualization workflows, or automated regression tests.
• Active or eligible to obtain and maintain a Top Secret / Sensitive Compartmented Information clearance.
