**Job Description** **Position Overview:** The Stanford Synchrotron Radiation Lightsource (SSRL), a Directorate of the SLAC National Accelerator Laboratory, is developing a state-of-the-art Hard X-ray Photoelectron Spectroscopy / Photoemission Electron Microscopy (HAXPES/PEEM) beamline with a strong focus on probing electronic and chemical states in buried layers of functional devices, particularly for microelectronics applications. We seek an outstanding Staff Scientist to play a leading scientific and technical role in the design, construction, commissioning of this new beamline, and - once in operation - in scientific program development and user support. The successful candidate will join the Materials Science Division and become an integral member of a highly collaborative, interdisciplinary research environment that combines staff-led scientific programs with close engagement and collaboration with the SSRL user community. This position offers a unique opportunity to shape a flagship SSRL beamline while advancing impactful research in microelectronics, semiconductor materials, quantum information science, and related fields. **Your specific responsibilities include but are not limited to:** Beamline and Endstation Development + Provide scientific leadership for and contribute to the conceptual design, technical development, construction, and commissioning of the HAXPES/PEEM beamline and associated endstation. Promote and represent the scientific objectives of the beamline to internal and external stakeholders. + Define and translate scientific requirements into technical specifications for beamline optics, monochromators, electron analyzer, and sample environments optimized for hard X-ray photoelectron spectroscopy. + Work closely with the project manager, engineers, technical staff, and scientists to develop robust, high-performance instrumentation. + Oversee system integration, testing, commissioning, and performance optimization. Scientific Research and Leadership + Develop and lead an independent and competitive research program using HAXPES/PEEM, aligned with the mission of the SSRL Materials Science Division. + Conduct frontier research in areas such as microelectronics, semiconductor devices, thin films, heterostructures, and buried interfaces. + Lead and participate in collaborative research projects involving SSRL staff, academic users, industrial partners, and other national laboratories. + Publish high-impact scientific results and present research at conferences and workshops. User Program Development and Collaboration + Play a central role in establishing and growing the HAXPES/PEEM user program at SSRL. + Engage with the user community to identify emerging scientific opportunities and guide the evolution of beamline capabilities. + Support users throughout the experimental lifecycle, including experimental design, beamtime execution, and data analysis. + Develop and maintain comprehensive user training and outreach activities, including workshops, tutorials, and documentation. Operations, Service, and Division Engagement + Manage routine beamline operations, endstation maintenance, and continuous performance improvement. + Ensure safe operation of the beamline in accordance with SLAC and DOE requirements. + Contribute to division-wide scientific initiatives, mentoring, outreach, and strategic planning. **Note** : Appointment at the Staff Scientist level is a regular-continuing position and requires a review and evaluation of documented scientific achievements, with approval by the Directorate Appointment and Promotion Committee. Applicants should include a cover letter, a research statement (including a summary of accomplishments), a curriculum vitae, a publication list, and the names of five references for future letters of recommendation. SLAC is a U.S. Department of Energy (DOE) laboratory operated by Stanford University and based in Menlo Park, CA. **To be successful in this position, you will bring:** + Ph.D. in physics, applied physics, materials science, or related discipline, with a minimum of 4 years of post-PhD research experience. + Demonstrated research excellence in materials science, supported by publications and experimental achievements. + Extensive knowledge and hands-on experience with HAXPES and/or PEEM techniques. + Demonstrated competence in developing, operating, and maintaining complex experimental systems at a synchrotron radiation facility. + Experience with facility operations and user support. + Strong written and verbal communication skills. + Demonstrated ability to work both independently and collaboratively in a team environment. **In addition, preferred qualifications include:** + Research experience in microelectronics or closely related fields. + Technical expertise in synchrotron beamline or endstation development, including operando or in situ sample environments. + Proficiency in data analysis, scripting, and sci
