Job summary

Mach Industries Inc. in Huntington Beach, CA seeks a Senior GNC Engineer specializing in Modeling and Simulation to build and validate vehicle models and simulation environments for autonomous aircraft and related platforms.

You will own modeling workstreams spanning flight dynamics, subsystem models, Monte Carlo analyses, and real-time testing, turning flight-test data into actionable insights for design.

Qualifications

• Bachelor's degree in a technical field.
• 5+ years developing/validating physics-based simulations of dynamic systems.
• Strong understanding of rigid-body dynamics, flight mechanics, and aerodynamics.
• Experience with six-degree-of-freedom simulations and integrated models.
• Experience with Monte Carlo analysis, uncertainty modeling, and statistical analysis.
• Experience with software-in-the-loop or hardware-in-the-loop simulation.
• Proficiency in C/C++ or Rust, and MATLAB/Simulink.

Responsibilities

• Own development and maturation of simulation capabilities across requirements, architecture, and validation.
• Translate GNC questions into simulation requirements, fidelity, interfaces, metrics, and criteria.
• Choose fidelity levels balancing accuracy, run time, maintainability and schedule.
• Implement equations of motion and interfaces in C/C++ or Rust, plus MATLAB/Simulink.
• Define simulation architecture and data formats for reuse across vehicles.
• Document assumptions, data sources, and validation evidence.
