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? SLAC National Accelerator Laboratory is one of 17 Department of Energy (DOE) National Laboratories. Operated by Stanford University on behalf of the DOE, SLAC develops and operates some of the world¿s premier science facilities, including the first hard X-ray free-electron laser. Researchers from SLAC and other premier institutions around the world use our facilities to investigate some of the most exciting and important problems facing our society. A suite of x-ray instruments for exploiting the unique LCLS-II scientific capabilities are being deployed and will soon be capable of producing petabytes of data per instrument per day. We are seeking a Software Developer to participate in the design and develop of a high-performance GPU-based data acquisition (DAQ) pipeline for SLAC-built custom detectors, integrating real-time data reduction and processing. This role will involve optimizing GPU-accelerated workflows, ensuring low-latency data handling, and collaborating with scientists and engineers to deploy scalable solutions for next-generation X-ray experiments at LCLS.

As a Software Developer, you will be a member of the Data Platforms Department of the Experimental Data Systems (EDS) Division, a multidisciplinary team of scientists, engineers, and software developers focused on supporting scientific instrumentation, data acquisition, data management, and data analysis systems. New employees will pair with experienced mentors to advance learning opportunities.

_SLAC is a U.S. Department of Energy (DOE) laboratory operated by Stanford University and based in Menlo Park, CA._

Your specific responsibilities will include:

+ Design and implement a GPU-accelerated DAQ pipeline for high-throughput detector systems.

+ Develop online data reduction algorithms (e.g., compression, feature extraction, filtering) to enable real-time processing.

+ Optimize kernels and parallel computing strategies for maximum throughput.

+ Integrate with SLAC¿s detector control systems and EPICS-based infrastructure.

+ Collaborate with beamline scientists, engineers, and HPC teams to ensure seamless data flow.

+ Benchmark and profile performance to minimize latency and maximize efficiency.

+ Document software architectures, APIs, and deployment procedures.

+ Contribute to all phases of a project, including ideation, program design, development, implementation, and data analysis.

+ Supervise professional staff, as necessary, working on all phases of application development projects.
