Mechanical Engineer

Mechanical Engineer Substrate is addressing one of the most important technological problems facing the United States. At the intersection of advanced manufacturing and cutting-edge physics, we are developing technologies that will reshape the semiconductor industry and strengthen America's technological leadership.

We are a team of world-class scientists, engineers, and technical experts building technology for the United States. Summary As a Mechanical Engineer, you will design and develop ultra-high vacuum (UHV) systems, precision mechanisms and high speed motion systems.

This role requires deep hands-on engineering experience in high-precision manufacturing environments combined with the ability to work autonomously on complex technical challenges.

You must be comfortable supporting scientists, engineers, and technical specialists working on parallel projects across multiple locations including external production sites. This is a full-time, in office position.
