AI Software Engineer (HPC & Scientific Workflows)

Argonne National Laboratory•Lemont, IL

1d•Hybrid

About The Position

The Argonne Leadership Computing Facility’s (ALCF) mission is to accelerate major scientific discoveries and engineering breakthroughs for humanity by designing and providing world-leading computing facilities in partnership with the computational science community. We help researchers solve some of the world’s largest and most complex problems with our unique combination of supercomputing resources and computational science expertise. The ALCF has an opening for a software engineer, targeting a broad range of capabilities to support the use of AI in science. The successful candidate will join the Data Services and Workflows group, which focuses on scientific workflows that combine large-scale data, simulations, analysis, and AI. In this position, the candidate will develop services and tools that allow AI models and agents to interact with simulations, data, and computing resources. This includes building APIs and workflow components for submitting and managing jobs, integrating AI models into scientific workflows, and enabling end-to-end workflows that combine data ingestion, model inference or training, and simulation. The focus of this role is on building robust, production-quality software systems that operate reliably at scale. The Data Services and Workflows group, and this position, involves work in a highly collaborative environment involving science application teams, academia and industry, as well as other national labs and agencies, to solve some of the world’s largest and most complex problems in science and engineering. The candidate will engage with science application teams and contribute to broader scientific initiatives.
