About The Position
Re:Build's mission is to ensure the next generation of important products are made, at scale, in America. They are laying the foundation for a better future by revitalizing America's manufacturing base and creating meaningful jobs. They operate an advanced, end-to-end manufacturing platform that partners with industrial companies and innovators to take products from concept to full-scale production in critical verticals including aerospace and defense, electrification, medical, energy and environment, and robotics and automation. The way they operate is guided by The Re:Build Way, 16 principles that shape how they collaborate, partner with customers and vendors, and contribute to communities. Reflow, a part of Re:Build, is building the first AI-powered platform purpose-built for hardware product development.
