Mechanical Design Engineer

Position Overview:
\n
The Stanford Synchrotron Radiation Lightsource (SSRL) directorate of SLAC National Accelerator Laboratory is a national user facility providing synchrotron radiation for research in biology, chemistry, engineering, environmental science, material science, medicine, and physics. SSRL operates and maintains the 3GeV electron storage ring SPEAR3, the associated injector facility, and synchrotron radiation beam lines on SPEAR3. The SSRL Beam Line Systems (BLS) division designs, constructs, and commissions new synchrotron radiation beam lines and retrofits existing beam lines for new capabilities or improved performance.
\n
The SSRL Beam Line Development (BLD) group works with scientists and other engineers in the design of synchrotron radiation instrumentation and optics. Components of x-ray beam lines range in complexity from simple mechanical supports to intricate optical assemblies providing precise manipulation of optical elements subject to high thermal loads in ultra-high vacuum.
