Mach is a defense manufacturing company that builds munitions to help the United States win future wars. Backed by $85M in funding from top venture firms, our small lean team ideates, designs, manufactures, and sells cutting-edge weapons to the Department of Defense.

Mach Industries is seeking a GNC Engineer (Navigation Focus) to develop and refine advanced navigation solutions for next-generation autonomous defense platforms. As a key member of our GNC team, you will be responsible for designing, implementing, and optimizing navigation algorithms that ensure precise, resilient positioning in contested and GPS-denied environments. Your expertise in sensor fusion, state estimation, and real-time navigation software will directly impact the performance and reliability of our unmanned systems in dynamic operational scenarios.

At Mach Industries, we build next-generation platforms that maintain an allied American edge. The future of warfare lies in decentralized autonomous systems, and we are committed to delivering scalable, adaptable solutions at unprecedented speed. As a GNC Engineer (Navigation Focus), you will work at the forefront of innovation, collaborating with cross-disciplinary teams to develop cutting-edge navigation technologies that enhance situational awareness, operational autonomy, and mission success in the modern battlespace.

Responsibilities:

• Lead the development and implementation of advanced navigation algorithms for autonomous and remotely operated defense platforms, ensuring robust and precise positioning in GPS-denied and contested environments.

• Design, simulate, and optimize sensor fusion techniques integrating IMU, GPS, LiDAR, vision-based navigation, and other aiding sensors to enhance navigation accuracy and reliability.

• Develop and refine Kalman filtering, Bayesian estimation, and other state estimation techniques to improve navigation performance across dynamic mission scenarios.

• Collaborate closely with guidance and control engineers to ensure seamless integration of navigation systems within the broader GNC framework.

• Implement and validate real-time navigation solutions using software-in-the-loop (SITL), hardware-in-the-loop (HITL), and flight test environments.

• Work with avionics and embedded systems teams to optimize navigation software for real-time execution on constrained computing platforms.

• Analyze and mitigate error sources affecting navigation performance, including sensor drift, signal interference, and environmental disturbances.

• Develop robust testing and validation frameworks for navigation systems, leveraging high-fidelity simulation tools and real-world field testing.

• Stay ahead of emerging navigation technologies, including alternative PNT (Positioning, Navigation, and Timing) solutions, AI-enhanced state estimation, and quantum sensing techniques.

• Ensure compliance with industry standards and defense-specific requirements for navigation systems, including resilience against jamming and spoofing threats.

Basic Qualifications:

• 5+ years of experience in navigation system development for aerospace, defense, or other mission-critical applications.

• Strong expertise in sensor fusion techniques, state estimation, and error analysis for navigation systems.

• Proficiency in developing navigation algorithms using MATLAB, Python, or C++.

• Experience with real-time software implementation and optimization for embedded systems.

• Deep understanding of inertial navigation systems (INS), GPS-aided navigation, and alternative PNT methods.

• Hands-on experience with navigation sensors such as IMUs, GNSS receivers, altimeters, LiDAR, and vision-based navigation systems.

• Bachelor’s or Master’s degree in Aerospace Engineering, Electrical Engineering, Computer Science, or a related field. A PhD is a plus.

Preferred Qualifications:

• Experience with navigation in GPS-denied environments, including terrain-relative navigation, visual odometry, and RF-based localization.

• Familiarity with defense industry standards and requirements for resilient PNT solutions.

• Expertise in AI/ML techniques for enhancing sensor fusion and state estimation.

• Hands-on experience with flight testing and navigation system validation.

• Strong knowledge of navigation error modeling and mitigation techniques.

• Experience with high-fidelity simulation tools such as Simulink, ROS, or Gazebo for navigation system development.
