Job description

About SLAC National Accelerator Laboratory
SLAC National Accelerator Laboratory is a U.S. Department of Energy laboratory operated by Stanford University. For over 60 years, SLAC has been at the forefront of scientific discovery, exploring how the universe works at the biggest, smallest, and fastest scales. From particle physics to astrophysics, materials science to biology, SLAC's world-class research facilities and scientific expertise drive innovation and push the boundaries of human knowledge.
About the Role
Do you enjoy collaborating with a diverse group of people to solve complex challenges? Does contributing to breakthrough discoveries in science and working in a world-leading research environment excite you?
The Application and User Services (AUS) group is seeking an energetic, forward-thinking software engineer to develop tools and workflows for science projects such as the Vera C. Rubin Observatory US Data Facility, hosted at SLAC. You will work with a team that supports multipleglobal, open-science, collaborations eager to leverage cutting-edge, best-in-class computing, platform and data services. We continually explore new platforms and technologies, and you will have a direct hand in shaping what the future of scientific computing at SLAC looks like.
S3DF is SLAC's centralized scientific computing facility, providing unified high-performance computing, storage, and data services to a broad portfolio of science programs. Current users include the Vera C. Rubin Observatory US Data Facility (supporting the Legacy Survey of Space and Time), LCLS (the Linac Coherent Light Source X-ray free-electron laser), ATLAS and other HEP experiments, and a growing number of additional programs. These experiments collectively generate and manage data at petabyte scale, with demanding requirements for throughput, reliability, and scientific reproducibility.
You will design, implement, and support the applications and APIs used to process, manage, and serve scientific data across these programs. You will contribute to troubleshooting and tuning the full portfolio of services used by scientists worldwide. You will have experience in data-intensive workflows and containerization and deployments on Kubernetes clusters. Some of your code will interface with authentication and authorization frameworks, so familiarity with Identity and Access Management (IAM) concepts is a plus.
A significant and growing part of this role will involve scientific data management at scale. The Facility manages a complex, multi-system data landscape spanning distributed data repositories, metadata catalogs, and data access layers. You will help us bring coherence, reliability, and formal stewardship practices to this environment: aligning data lifecycle policy with operational reality, ensuring metadata integrity, and building the tooling and workflows that let us manage data responsibly across its full lifetime.
We encourage open dialog, free thinking, cooperation, and a growth mindset. This is an opportunity to learn, enable groundbreaking science, and develop your skills in a uniquely collaborative scientific computing environment.
Key Responsibilities Application Development & Integration
  • Design, implement, and maintain applications and APIs for S3DF science programs, enabling scientists worldwide to access, process, and analyze large-scale experimental and observational datasets
