Job opportunity: NIWA / NeSI seeking a HPC and Cloud DevOps Engineer

NIWA has an exciting opportunity for an experienced Systems Engineer to make a significant contribution to the New Zealand research landscape by working within NeSI.

A key component of NIWA's research infrastructure is the High Performance Computing Facility (HPCF), which is used to support research activities in climate, chemistry climate, weather, river flood, sea state, ocean, sea-level, and inundation modelling and forecasting, as well as an operational environmental forecasting system (EcoConnect).

Within NeSI the system also supports the High-Performance Computing (HPC) requirements of researchers within the national research community. The core HPC platforms have recently been refreshed with the deployment of a capacity cluster (HPE/Cray CS400 and CS500) and capability supercomputer (HPE/Cray XC50) in a tightly integrated design, sharing core high-performance filesystems, nearline storage, and related operational infrastructure.

You will support and further develop an HPC infrastructure and platform which delivers a wide range of services. You will help to ensure the delivery of a flexible and robust computational environment for scientific research whilst maintaining a stable platform for delivery of NIWA operations and NeSI's business systems. Our team is trusted to build the systems that run our newest cutting-edge platforms that power the New Zealand research community.
