Lawrence Livermore National Laboratory

Want to work on open source for science? Come work on the Spack package manager at LLNL! Spack is a tool for building and installing scientific software on laptops, clusters, and the world’s largest supercomputers. It allows users to build optimized packages with many different compilers, build options, optimization flags, and dependency versions. Spack facilitates individual development workflows, but also allows supercomputing facilities to deploy large suites of software for their users. LLNL is home to the world’s 2nd fastest supercomputer, Sierra, as well as ~25 other large HPC clusters. Your work will directly support simulations run on these machines, and you’ll get to collaborate with other DOE national laboratories via the Exascale Computing Project. Spack has an international community, and you'll also collaborate with major supercomputing sites around the world.
