Founded in 2023, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 350 employees, we operate with startup agility and ambition.

Depending on your background and team placement, you might work on:

Autonomous systems — guidance, control, and navigation software for unmanned platforms
Embedded firmware and real-time software for flight and drive systems
Mechanical and structural design, manufacturing, and test of hardware components
Propulsion, energetics, or systems integration for new defense platforms
Tools, infrastructure, and simulations that accelerate engineering velocity

What We're Looking For

Enrollment in a BS, MS, or PhD program in mechanical, aerospace, electrical, computer science, or a related engineering discipline
Intellectual curiosity and the drive to own problems end-to-end
Genuine interest in defense technology, national security, or the future of autonomous systems
