Job DescriptionWe 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.

Job Responsibilities

- 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.
- Administer internally hosted services and applications, including the intranet and the ticketing system.
- 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.
- Manage endpoint security, alert response, and vulnerability remediation, and maintain the technical controls required by ISO/IEC 27001.
- Automate recurring operational work and keep configuration standards documented.

Required Skills
- Solid Linux systems administration experience, including networking, storage, and troubleshooting at the OS level.
- Hands-on experience administering HPC clusters with Slurm: partitions, QOS, accounting, and job troubleshooting.
- 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.
- Experience managing endpoints and user accounts across mixed operating systems, including identity and access management.
- Working knowledge of information security practice: access control, endpoint protection, vulnerability management, and incident response.
- Ability to document your work clearly and to communicate with non-specialist users.

We will value experience in
- AWS Parallel Cluster or other cloud HPC deployments.
- GPU infrastructure: CUDA toolchains, drivers, and scheduling GPU workloads.
- Compiling and installing open-source or scientific software, resolving dependency issues, and delivering functional builds to end users.
- ISO/IEC 27001 implementation or audit support and GDPR technical controls.
- Security monitoring and SIEM tooling, and infrastructure monitoring.
- Working in a client-facing or regulated environment where infrastructure is part of a service commitment.
