NDT Inspector

Engineering moves at software speed. Manufacturing doesn't. Yet.


Machina Labs is changing that. We build intelligent, software-defined factories that produce complex metal structures directly from digital design. By integrating advanced metal forming, robotics, and automated production inside a flexible factory architecture, we enable customers to move from prototype to production in weeks, not years.


Backed by Lockheed Martin, Toyota, and NVIDIA, we're building the manufacturing infrastructure that defense, aerospace, and advanced mobility programs will run on.


If you want to work on hard problems that matter and see them fly, drive, and defend, this is the place.
