Lead Mechanical Engineer for Precision Positioning and Alignment Systems

Website advlightsource Advanced Light Source (ALS)

Lawrence Berkeley National Laboratory (LBNL) Engineering Division has an immediate opening for a Lead Mechanical Engineer to join the team.

This is a position within the Engineering Division that supports the various user facilities and projects at LBNL. Supported facilities and projects include, but are not limited to: the Advanced Light Source, the Advanced Light Source Upgrade project, DUNECMB-S4, and engineering support for the wide array of science and technology at LBNL.

The Lead Mechanical Engineer will be matrixed to the Advanced Light Source Upgrade (ALS-U) and will serve as the technical lead for the Supports and Alignment group. You will plan and coordinate design, fabrication, testing, and installation activities of sub-systems such as large magnet assemblies. Positioning and alignment of the sub-systems within the accelerometer system within a few-micrometers accuracy will be a key parameter to the success of this mega project.

ALS-U is a planned upgrade of the main electron particle accelerator complex of the Advanced Light Source (ALS) at Lawrence Berkeley National Lab that will provide revolutionary x-ray capabilities with up to 1000 times brighter x-ray beams. More information can be found at: http://als.lbl.gov/als-u/overview.  The project is scheduled for completion in 2026. This 1⁄2 billion dollar project has a talented and diverse team upgrading the existing light source. Join the team and be an integral part in the creation of the United States’ flagship soft x-ray light source.

Within the ALS-U Supports and Alignment team, the Lead Mechanical Engineer will advance the storage ring support and alignment systems through final design, fabrication, testing, installation and integration. The engineer will perform 3D CAD design work, provide supporting analysis, develop procurement packages and specification documents, serve as the technical representative for procurement contracts, develop test plans and verification methods.  The engineer will work together with mechanical designers to develop fabrication drawings and associated documents. You will work with the technicians on the testing and commissioning of the assemblies.

The Lead Mechanical Engineer will use a broad array of analytical, computational, experimental, instrumentation, and hardware design skills in the development of particle accelerator components:

  • Initiate the design, development, fabrication, and implementation of mechanical systems and components. Design and analyze mechanical equipment, detectors, and accelerator components and devices.
  • Independently apply expertise in select core disciplines of mechanical design, analysis,  and instrumentation to enable advances over a broad spectrum of scientific programs of national importance.
  • Embedded within a larger project, provide engineering oversight and management of sub-projects, integrating multiple engineering and scientific components.

This is a matrixed position that will provide opportunities for changing assignments/projects as work is completed or as project/program scope changes.

LBNL was based on a principle of team science.  It is the premise that everyone on the team or in support of the team is a contributor.  No idea is ignored.  All ideas are considered and included in the discussion.  It’s an exciting time to join our growing team!

This position will be hired at a level commensurate with the business needs; and skills, knowledge, and abilities of the successful candidate.
