High Performance Computing Engineer - Mid-level

HPC Engineer Who You Are You are a talented, multidiscipline engineer versed in getting the best performance out of systems. You are familiar with High Performance Computing using both CPU and GPU based systems. You understand scheduling using SLURM, computing using MPI, and operating software at scale. What you will be doing Playing a key role in defining and operating some of the most complex compute platforms that the client has to bring to bear against complex problems. These systems enable complex analysis, simulation and modeling leveraging massively parallel computing and disparate holding of very large data sets, to answer difficult questions. To do this you will assist the users in deploying jobs to these systems to harness the capabilities of these systems producing answers in the form of analytic product, models and simulations. This mission enablement is the heart of the hardest problems to solve.
