About The Position

The Mechanical Engineering Department within the Engineering Division at Lawrence Berkeley National Laboratory (LBNL) is seeking a skilled Mechanical Engineering Machinist to join our team. The Engineering Division provides essential technical expertise and transformative technologies that power scientific discovery across the Laboratory. In this role, you will perform journey-level machining assignments, applying intermediate-level knowledge, innovation, and creativity to support mechanical and shop-related operations for groundbreaking research projects. In this role, you will provide critical technical support in journey-level machining technology, using both conventional and Computer Numerical Controlled (CNC) machinery to program, set up, and manufacture complex hardware components and assemblies. You will collaborate closely with technicians, designers, engineers, and scientists to offer design-for-manufacturability advice and fabricate specialized work-piece fixtures for unique or production machine tool applications. May be assigned/rotated to a matrix assignment to provide direct machining support to specific projects/programs. We're here for the same mission, to bring science solutions to the world. Join our team and YOU will play a supporting role in our goal to address global challenges! Have a high level of impact and work for an organization associated with 17 Nobel Prizes!
