Jobs in Huntington Beach, CA

About 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. The salary range for this role is an estimate based on a wide range of compensation factors, inclusive of base salary only. Actual salary offers may vary based on (but not limited to) work experience, education and training, critical skills, and business considerations. Highly competitive equity grants are included in most offers and are considered part of Mach’s total compensation package.

What you'll bring

• 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.
• 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.
