Job summary

CHAOS Industries, founded in 2022 and headquartered in Los Angeles, seeks a Modeling & Simulation Engineer for Missiles. You will develop, integrate, and validate dynamic simulations for guided weapons, interceptors, and related flight vehicles across 3-DOF/6-DOF environments and real-time hardware-in-the-loop setups.

Candidate depth in missile modeling areas, strong programming in MATLAB/Python/C++, and experience with simulation environments are essential.

Qualifications

Bachelor’s degree in aerospace engineering, mechanical engineering, electrical engineering, computer engineering, computer science, physics, applied mathematics, or a related technical discipline, or equivalent demonstrated expertise.
Relevant experience in missile or flight-vehicle modeling and simulation, flight dynamics, GNC, trajectory analysis, weapon-system performance, or a closely related field.
Hands-on experience developing, integrating, or using 3-DOF or 6-DOF dynamic simulations.
Strong fundamentals in flight mechanics, rigid-body dynamics, coordinate systems and transformations, numerical integration, control or estimation concepts, and dynamic-system analysis.
Demonstrated depth in at least one relevant missile modeling area, such as flight dynamics and vehicle modeling; guidance-law development or analysis; flight-control, autopilot, or control-system modeling; navigation, estimation, or multisensor integration; trajectory optimization or weapon-system performance analysis; seeker, tracker, fire-control, or terminal-engagement integration; or real-time simulation, HITL, or HWIL.
Strong programming ability in at least one scientific or analytical environment such as MATLAB, Python, or C++.
Experience performing Monte Carlo analysis, error-budget analysis, sensitivity analysis, robustness analysis, uncertainty quantification, or design of experiments.
Experience validating or correlating dynamic models against analytical references, subsystem-test data, laboratory data, telemetry, flight-test data, range data, or other authoritative sources.
Experience with system requirements, subsystem interfaces, test objectives, verification methods, and performance criteria.
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.

Responsibilities

Develop, integrate, and maintain 3-DOF and 6-DOF flight and engagement simulations for missile systems and related flight vehicles.
Implement and validate equations of motion, coordinate-frame transformations, rigid-body dynamics, numerical integration, kinematics, environmental models, and vehicle-state propagation.
Develop or integrate models of aerodynamics, propulsion, mass properties, inertia, actuators, control surfaces, thrust-vector control, navigation sensors, IMUs, GPS, seekers, fuzing, launch and ejection systems, staging, separation events, atmospheres, winds, gravity, targets, and threats as applicable.
Integrate guidance algorithms, navigation and estimation functions, autopilots, control laws, seeker and tracker functions, fire-control interfaces, tactical software, embedded flight software, and hardware models into closed-loop simulations.
Evaluate trajectory and engagement performance, including launch and intercept envelopes, time of flight, time to intercept, acquisition and handover behavior, miss distance, accuracy, stability, robustness, actuator usage, control margins, navigation error, seeker performance, terminal performance, and degraded or failure modes.
Develop error budgets and perform Monte Carlo analysis, sensitivity analysis, uncertainty quantification, covariance analysis, design of experiments, and robustness studies.
Support system-design trades involving vehicle configuration, guidance concepts, control architecture, sensor selection, actuator performance, propulsion, aerodynamics, launch conditions, and operational scenarios.
Translate system and subsystem requirements into model requirements, simulation cases, performance measures, verification methods, and objective evidence.
Integrate models and flight or tactical software into desktop simulation, SIL, SITL, HITL, HWIL, real-time, processor-in-the-loop, and large-scale batch environments as applicable.
Support hardware and software integration laboratories, including interface definition, timing analysis, real-time execution, hardware stimulation, test automation, and anomaly investigation.
Develop preflight predictions, test scenarios, test points, expected-performance envelopes, and flight or range-test analysis products.
Reduce and analyze telemetry, laboratory, ground-test, captive-carry, flight-test, and range data.
Perform postflight reconstruction, model correlation, parameter estimation, root-cause analysis, and simulation-to-test discrepancy resolution.
Develop and maintain simulation software, reusable model components, model APIs, configuration systems, scenario-generation tools, data pipelines, visualization tools, analysis workflows, and automated regression tests.
Produce model documentation, assumptions and limitations, validation evidence, performance reports, engineering-review material, and customer or program deliverables.
