Build Engineer

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.

Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security.

Mach Industries is seeking a Build Engineer to own the transformation of our products from new designs to reality. In this role, you will work closely with the Product Engineering and Manufacturing teams to build first articles, enable rapid design iteration, and capture critical lessons that shape how products mature into production. This is a hands-on role that demands resourcefulness, speed, and technical rigor.

At Mach Industries, we are building decentralized, autonomous systems to maintain an allied American edge in modern warfare. As a Build Engineer, you will play a pivotal role in proving out design concepts through the initial manufacturing phase. Working with a world-class engineering team, you will bridge the gap between design and manufacturing, delivering solutions that ensure manufacturability, cost-efficiency, and mission-critical reliability.

• Act as the engineering owner for prototype builds across multiple products.

• Translate design intent into practical build steps, processes, and checklists for technicians.

• Debug and resolve design/manufacturability issues directly with design engineers.

• Actively participate in design reviews to ensure manufacturability of design concepts.

• Capture lessons learned and feed them back into the design and production system.

• Source and coordinate quick-turn parts and prototype tooling.

• Partner with technicians to train, enforce standard work, and improve safety/ergonomics.

• Bachelor’s degree in mechanical, aerospace, manufacturing engineering, or equivalent experience.

• 1+ years in production manufacturing, process engineering, or industrialization (internship and school projects experience qualifies).

• Strong troubleshooting, problem-solving, and communication skills.

• Familiarity with GD&T, tolerance analysis, and process capability.

• Hands-on experience with shop floor processes (machining, welding, composites, additive manufacturing, assembly, test).

• Willingness to be on the floor daily, working shoulder-to-shoulder with technicians.

• Experience in aerospace, defense, automotive, or other high-rate production environments.

• Ability to operate autonomously in ambiguity with minimal documentation.

• “Get it built” mindset with a bias for speed.

Additional Requirements

• Available to work extended hours and weekends as needed
