The Role

Mach Industries is seeking a New Graduate Guidance, Navigation, and Controls (GNC) Engineer to support the development of next-generation autonomous defense systems. In this role, you will help design, simulate, test, and integrate algorithms that enable our vehicles to navigate, maneuver, and complete their missions.

You will work closely with flight software, avionics, aerodynamics, propulsion, systems, and flight-test teams to take GNC capabilities from early simulation through hardware testing and flight.

Key Responsibilities

  • Develop and test guidance, navigation, and control algorithms for autonomous aircraft and missile systems.
  • Build simulations and models to evaluate vehicle dynamics and system performance.
  • Support the development of flight-control laws, guidance algorithms, navigation filters, and state-estimation methods.
  • Analyze flight and test data to evaluate performance and identify opportunities for improvement.
  • Support software-in-the-loop, hardware-in-the-loop, ground, and flight testing.
  • Integrate GNC algorithms with flight software, sensors, actuators, avionics, and propulsion systems.
  • Perform Monte Carlo simulations and sensitivity analyses across different operating conditions.
  • Document algorithms, simulation results, test procedures, and technical findings.
  • Troubleshoot system-level issues alongside multidisciplinary engineering teams.

Required Qualifications 

  • Bachelor’s, master’s, or doctoral degree in Aerospace Engineering, Mechanical Engineering, Electrical Engineering, Computer Engineering, or a related field.
  • Graduating by summer 2027
  • Coursework or project experience in dynamics, controls, estimation, navigation, robotics, or flight mechanics.
  • Experience with MATLAB, Simulink, Python, C++, or a similar technical programming language.
  • Strong understanding of linear algebra, differential equations, and control-system fundamentals.
  • Experience gained through internships, research, academic projects, or student engineering teams

Preferred Qualifications

  • Experience with flight-control design, trajectory optimization, sensor fusion, or state estimation.
  • Familiarity with Kalman filters, PID control, optimal control, or nonlinear control methods.
  • Experience developing six-degree-of-freedom vehicle simulations.
  • Exposure to inertial measurement units, GPS, actuators, or other flight-system hardware.
  • Experience with software-in-the-loop or hardware-in-the-loop testing.
  • Participation in rocketry, UAV, robotics, Design/Build/Fly, Formula SAE, or similar technical teams.
  • Familiarity with Git, Linux, and modern software-development practices.
  • Experience analyzing ground-test or flight-test data.

Additional Requirements

  • Available to work extended hours and weekends as needed.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
