## Job description

About Re:Build

At Re:Build, our mission is to ensure the next generation of important products are made, at scale, in America. We are laying the foundation for a better future for our customers, employees, and communities by revitalizing America's manufacturing base and creating meaningful jobs across the country, including in historically deindustrialized regions.

We operate an advanced, end-to-end manufacturing platform that partners with industrial companies and innovators to take products from first concept to full-scale production in critical verticals including aerospace and defense, electrification, medical, energy and environment, and robotics and automation.

The way we operate is as important as the work we do. It's guided by The Re:Build Way, 16 principles that shape how we collaborate with each other, partner with our customers and vendors, and contribute to the communities where we operate. (link to [The Re:Build Way principles](https://rebuildmanufacturing.com/about/rebuild-way/))

We have extensive in-house laboratory and rapid prototyping capability including CNCs, 3D printers, waterjet and laser cutters, which help facilitate our ability to prototype and innovate fast. As part of Re:Build Manufacturing, we are able to collaborate with other member sites and leverage a greater network of capabilities including composites, industrial design, structural analysis, and embedded systems design.

## Who we are Looking For

- Experience designing biomedical or automation products a plus

The base salary range for this position is $165,320.12 - $247,980.18 per year. This range represents the Company’s good faith estimate of the base compensation for this role at the time of posting.  Actual compensation will be determined based on several factors, including but not limited to relevant experience, skills, qualifications, internal equity, and geographic location.
