Staff Engineer 4 - Mechanical Design, SSRL

Position Overview:

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.

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.

Your specific responsibilities include:

• Lead the effort to design advanced mechanical systems and state of the art experimental facilities to serve the SSRL beamline user community.


• Lead component design and development activities, including concept generation, engineering analysis, 3D CAD modeling, material selection, application of engineering standards, GD&T/tolerancing, detailed drawings, vendor coordination, procurement support, and preparation of technical documentation in accordance with SSRL standards.


• Manage the engineering process from conception through design, construction, and field installation. This includes interfacing with both physicists and scientists to develop project requirements and mechanical technicians to ensure proper component assembly and installation.


• Act as project manager for advanced component or facility construction by leading teams of senior mechanical engineers, technicians, and other specialized technical professionals.


• Participate in the assembly of a world-class group of engineers to serve the SSRL user community.

To be successful in this position you will bring:

• Bachelor's degree in mechanical engineering, coupled with 8+ years of hands-on experience in CAD-based mechanical design.


• Led full-lifecycle projects from design and fabrication through installation and commissioning.


• Subject matter expert in precision engineering, kinematic principles, mechanical fabrication, and ANSI documentation.


• Combines analytical problem-solving with innovative design conceptualization.


• Proficient in deploying FEA software to solve complex thermal, thermal stress, and structural problems, with a focus on identifying optimal design solutions.


• Skilled at conveying technical information to physicists, engineers, and technicians, both verbally and in writing.

In addition, preferred requirements include:

• Advanced degree (Master's or PhD) in Mechanical Engineering and hands-on experience in CAD-based mechanical design.


• Designed complex, high-precision mechanisms and maintained strict vacuum compatibility standards.


• Integrated optical components (monochromators, collimators, mirrors) into specialized systems.


• Engineered UHV-compatible components applying advanced vacuum design principles.


• Verified assembly precision using Faro arms, CMMs, and various hand-held metrology tools.

SLAC Employee Competencies:

• Effective Decisions: Uses job knowledge and solid judgment to make quality decisions in a timely manner.


• Self-Development: Pursues a variety of venues and opportunities to continue learning and developing.


• Dependability: Can be counted on to deliver results with a sense of personal responsibility for expected outcomes.


• Initiative: Pursues work and interactions proactively with optimism, positive energy, and motivation to move things forward.


• Adaptability: Flexes as needed when change occurs, maintains an open outlook while adjusting and accommodating changes.


• Communication: Ensures effective information flow to various audiences and creates and delivers clear, appropriate written, spoken, presented messages.


• Relationships: Builds relationships to foster trust, collaboration, and a positive climate to achieve common goals.

Physical requirements and working conditions:

• Consistent with its obligations under the law, the University will provide reasonable accommodation to any employee with a disability who requires accommodation to perform the essential functions of the job.

Work Standards:

• Interpersonal Skills: Demonstrates the ability to work well with Stanford colleagues and clients and with external organizations.


• Promote Culture of Safety: Demonstrates commitment to personal responsibility and value for environment, safety and security; communicates related concerns; uses and promotes safe behaviors based on training and lessons learned.Meets the applicable roles and responsibilities as described in the ESH Manual, Chapter 1 General Policy and Responsibilities:


• Subject to and expected to comply with all applicable University policies and procedures, including but not limited to the personnel policies and other policies found in the University's Administrative Guide:


• As a national laboratory, SLAC National Accelerator Laboratory is responsible for adhering to the Homeland Security Presidential Directive 12 (HSPD-12) and Department of Energy (DOE) Order 473.1A, which require employees to obtain and maintain a HSPD-12 Personal Identity Verification (PIV) Credential. To obtain this credential, employees must successfully complete the applicable tier of federal background investigation post hire and receive a favorable federal adjudication. The tier of federal background investigation will be determined by job duties and national security or public trust responsibilities associated with the job. All tiers of investigation include a declaration of illegal drug activities, including use, supply, possession, or manufacture within the last 1 to 7 years (depending on the applicable tier of investigation). Illegal drug activities include marijuana and cannabis derivatives, which are still considered illegal under federal law, regardless of state laws.
