The Legacy Survey of Space and Time (LSST), which will be carried out by the Vera C. Rubin Observatory, is the US flagship ground-based astronomical survey of the 2020s. We are looking for seasoned and experienced full-stack Senior Systems Software Engineers to work at the intersection of state of the art computer science and cutting edge astrophysics. The engineers will design and build an analysis framework run on the cloud or high-performance computing (HPC) systems that can store, search, analyze and annotate data of the volume and complexity of the LSST data. This framework will provide an interface for the astronomical community to run real time and batch analyses (e.g. to search for one-in-a-million events in continuous streams of data). You will shape, drive and ex
