Modeling & Simulation Engineer, Radars

CHAOS Industries•El Segundo, CA

3d•$140,000 - $190,000•Onsite

About The Position

CHAOS Industries is hiring a Modeling & Simulation Engineer for Radars to develop, integrate, and validate models of radar and RF sensing systems. The role spans analytical, behavioral, measurement-level, signal/IQ-level, and closed-loop system models, with model fidelity selected to suit the design decision, software integration activity, test event, or verification objective. The engineer will work with radar architecture, RF and antenna, signal processing, tracking, embedded software, systems engineering, test, and product teams. Candidates with depth in one or more relevant modeling and simulation domains are encouraged to apply; experience in every listed area is not expected. The Modeling & Simulation team builds simulation capabilities used to design, integrate, test, and validate advanced aerospace and defense systems. It develops physics-based models, simulation environments, and analysis tools to evaluate system behavior, improve designs, and reduce risk before hardware design, integration, testing, and fielding. CHAOS Industries develops a multi-product defense portfolio powered by Coherent Distributed Networks (CDN™), serving warfighters, commercial air operators, and border protection teams. Founded in 2022, the company has raised $1 billion and is headquartered in Los Angeles, with offices in Washington, D.C., San Francisco, San Diego, Seattle, and London.

Responsibilities

Develop, integrate, and maintain physics-based and performance-based models of radar and RF sensing systems.
Build analytical radar-performance, behavioral sensor, measurement-generation, signal or complex-IQ, radar-mode, tracker, and closed-loop system models at appropriate levels of fidelity.
Model radar effects, including 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.
Develop or integrate detection, thresholding, discrimination, measurement extraction, data association, tracking, estimation, classification, sensor fusion, radar-mode, and resource-management functions as applicable.
Build target, scene, geometry, trajectory, environmental, and threat models to evaluate radar performance in operationally relevant scenarios.
Perform design trades, sensitivity studies, Monte Carlo analysis, uncertainty quantification, and design of experiments.
Characterize radar performance using relevant metrics, including signal-to-noise or signal-to-interference-plus-noise ratio, detection and false-alarm performance, coverage, detection range, measurement and track accuracy, revisit and update rates, latency, track capacity, and robustness.
Integrate radar algorithms and software, embedded software, sensor and target models, and hardware interfaces into applicable SIL, SITL, HITL, HWIL, real-time, or large-scale batch simulation environments.
Validate and correlate models against analytical references, laboratory and chamber measurements, calibration data, recorded signal or IQ data, radar-range data, field-test data, flight-test data, and other authoritative sources.
