Scientific Data Management Job ID 6301 Location SLAC - Menlo Park, CA Full-Time Regular **SLAC Job Postings** **Position Overview** Do you enjoy collaborating with a diverse group of people to solve complex challenges? Does contributing to breakthrough discoveries in science and working with unique experimental instrumentation in a world-leading scientific research environment excite you? The Experimental Data Systems (EDS) division within the Linac Coherent Light Source (LCLS) Directorate at SLAC is seeking a Big Data Architect to work on the development of data management tools that enable LCLS scientific capabilities. LCLS is the world¿s premier X-ray free-electron laser (XFEL) with a suite of X-ray instruments capable of generating large, high-velocity, high-variety datasets used to elucidate atomic structures and dynamics at the femtosecond timescale. The evolution of science and experimental techniques on these instruments, along with upgrades in the X-ray FEL source and optical lasers (LCLS-II and LCLS-II-HE), benefits from real-time feedback, access to significant computing power, innovative analysis methods such as those employing AI/ML, and the ability to automate experiments from execution to analysis. This position will focus on the development, integration, and management of systems to transport, store, search, retrieve, analyze, and visualize petascale scientific datasets. The successful applicant will participate in the effort to develop systems that enable the seamless transfer of data to Department of Energy Leadership Class Facilities for real-time analysis. A significant aspect of the role will be to support, maintain, and optimize existing EDS software and hardware platforms at the SLAC Shared Data Facility (S3DF) to support LCLS operations. As a Big Data Architect in the LCLS Data Management Department, you will work within an interdisciplinary team of software developers, scientists, and engineers and oversee scientific data management systems, including data curation, timely data transfer, and archival integrity for LCLS.
