We are seeking an HPC and IT Infrastructure Engineer to manage the computing environment our science runs on. In this role, you will be in charge of the clusters where our simulations execute, the network and devices our team works from, and the security controls that protect both. You will work directly with computational chemists and software engineers whose results depend on the cluster being fast and available, and you will have a real say in how the environment is designed. Expect roughly 60% of your time on HPC and infrastructure engineering and 40% on IT services and security operations.
Target start date: immediately.
Administer the on-premises HPC cluster and AWS ParallelCluster environments, including scheduler, queues, accounting, and capacity, with an eye on cloud spend.
Maintain the scientific software stack (modules, containers, compilers, MPI, CUDA) and troubleshoot performance and reliability issues alongside the researchers running the jobs.
Support clusters dedicated to client projects, including maintenance and documentation.
Operate the office network, servers,



storage, and backups.
Provide first- and second-line user support through our internal ticketing system, covering user onboarding and offboarding, credentials and access control, and the management of laptops, workstations, and company devices.
Automate recurring operational work and keep configuration standards documented.
Solid Linux systems administration experience, including networking, storage, and troubleshooting at the OS level.
Experience building or maintaining scientific software environments: module systems, containers, compilers, and MPI.
Experience with AWS, particularly compute, storage, and networking services, and cost awareness in cloud environments.
Scripting and automation (Bash, Python) and configuration management or infrastructure as code.
Working knowledge of information security practice: access control, endpoint protection, vulnerability management, and incident r
