Shahzeb Siddiqui is a HPC Programming Environment Engineer at Lawrence Berkeley National Laboratory at NERSC. He is part of Programming Environments and Models which is responsible for development of HPC programming models and software runtimes that enable current and future science on NERSC system. Shahzeb is responsible for engaging with NERSC user community through user support tickets, user outreach, training, documentation. Shahzeb is a member of the Software Deployment (SD) group in Exascale Computing Project (ECP) where he is responsible for building and testing the Spack Extreme-Scale Scientific Software Stack (E4S) at the DOE facilities.

Shahzeb is the creator of buildtest an HPC testing framework to automate build and execution of tests. He also created lmodule, a Python API for module system which is a spin-off from buildtest project and it is a standalone API that can be used for testing modules.

Shahzeb created slurm utility called jobstats which is a wrapper to sacct and sreport to show slurm job details.

Shahzeb has experience installing and managing large software stack, cluster manager (Bright Cluster Manager, Cobbler), configuration management (Ansible), GPFS, Slurm and LSF. Shahzeb is an experienced Developer, Dev-Ops, System Administrator and often involved in open-source projects.

Shahzeb Siddiqui started out his career in High Performance Computing (HPC) in 2012 at King Abdullah University of Science and Technology (KAUST) while pursuing his Masters. His focus in HPC includes Parallel Programming, Performance Tuning, Containers (Singularity, Docker), Linux system administration, Scientific Software Installation and testing, Scheduler Optimization, and Job Metrics. Shahzeb has held multiple roles in his HPC career in the following companies: Dassault-Systemes, Pfizer, Penn State, and IBM. Prior to 2012, he was a software engineer holding multiple roles at Global Science & Technology, Northrop Grumman, and Penn State.
