GNC Engineer, Modeling & Simulation

The Role

Mach Industries is seeking a GNC Engineer, Modeling & Simulation to design, build, and maintain high-fidelity aircraft simulation environments in support of Guidance, Navigation, and Control (GNC) development. You will be responsible for realizing equations of motion in software, developing and validating aerodynamic and plant models, and creating the simulation infrastructure required for both software-in-the-loop (SITL) and hardware-in-the-loop (HITL) testing.

This role is ideal for an engineer who thrives at the intersection of physics-based modeling, software development, and systems integration. You'll collaborate closely with aerodynamicists, controls engineers, and hardware teams to ensure Mach's autonomous platforms are accurately modeled and rigorously tested before flight.
Key Responsibilities

• Develop and maintain high-fidelity flight dynamics and vehicle simulation models.
• Implement equations of motion in C++ and Python for real-time and offline simulation environments.
• Collaborate with the aerodynamics team to incorporate aerodynamic models derived from CFD and wind tunnel testing.
• Perform system identification and parameter estimation to generate accurate plant models.
• Build and sustain simulation infrastructure supporting GNC verification and validation in SITL and HITL environments.
• Develop test harnesses, logging frameworks, and automated validation tools for simulation assets.
• Integrate with CI/CD pipelines to ensure continuous simulation regression testing and model integrity.
• Document and maintain model assumptions, configurations, and validation results.

Required Qualifications

• Bachelor's degree in Engineering, Physics, or Mathematics.
• 3+ years of experience developing and deploying navigation or simulation systems.
• Proficiency in C++ and Python, with strong understanding of software design for simulation environments.
• Experience using modern software development tools such as Git and Jira.
• Familiarity with CI/CD strategies and tools for code integration and automated testing.

Preferred Qualifications

• Experience modeling fixed-wing aircraft dynamics and control systems.
• Deep understanding of atmospheric flight kinematics and aerodynamics.
• Familiarity with satellite constellation modeling or orbital mechanics.
• Experience with radar seeker modeling and sensor integration.
• Background in real-time systems or embedded simulation environments.
