Lead Engineer - X-ray Instrumentation Development Job ID 6134 Location SLAC - Menlo Park, CA Full-Time Regular **SLAC Job Postings** **Position overview** The Linac Coherent Light Source (LCLS) is an internationally preeminent science facility, operated by Stanford University at the SLAC National Accelerator Laboratory on behalf of the Department of Energy, Office of Science. This facility provides world-leading scientific capabilities to a global user community, covering a very broad research portfolio that includes the development of advanced materials and chemical catalysts for clean energy systems; drug discovery for modern pharmaceuticals; and fundamental studies of astrophysical phenomena. We are seeking a candidate to fill the position of Staff Mechanical Engineer. The successful candidate will help drive a dynamic and exciting environment, leading the engineering development and operation of a broad array of scientific instruments that operate at the frontier of science. Major upgrades to LCLS are currently underway, representing well over a billion dollars of investment. Over the next five years, LCLS will design and deliver a new suite of science instruments to transform this field, taking advantage of the orders-of-magnitude increase in X-ray beam power as the pulse repetition rate is increased from 120 pulses/second to 1 million/second. This drives the need for entirely new capabilities in X-ray optics, beam diagnostics, cryogenics, ultra-high vacuum assemblies, and precision opto-mechanical systems. In addition, a major multi-year project is underway to upgrade the LCLS facility with a Petawatt laser, enabling high peak power optical and x-ray photons to combine on target, providing world-leading capabilities in the field of fusion science. The successful candidate will join the LCLS mechanical engineering team. The successful candidate will lead the development of new X-ray and Laser science instruments, X-ray and optical beamline systems, and help lead the development of new operational capabilities for the LCLS facility.
