Powering Precision: Engineering Scalable HPC Solutions for Tomorrow’s Innovations.
What you will do
As an HPC Unix Engineer, you are responsible for managing, optimizing, and supporting our High Performance Computing (HPC) infrastructure within a critical ICT environment. You will help ensure the performance, scalability, and stability of compute clusters, with a focus on SLURM, Open OnDemand, and advanced HPC tooling. You’ll work within a multidisciplinary team, supporting users with demanding workloads across simulation, EDA, and numerical modeling domains.
Key Responsibilities
Operational Support & Incident Management
Provide 2nd-line support for Linux and HPC environments, resolving issues related to job scheduling, software usage, and cluster performance.
Analyze and troubleshoot performance issues, resource management challenges, and job failures.
Support users through Open OnDemand portals, including both interactive and batch workloads.
Follow ITIL-based processes for incidents, changes, and service requests.
Monitor and analyze system and job metrics using tools like Prometheus and Grafana.
HPC System Management
Manage SLURM clusters, compute nodes, GPU resources, and workload optimization.
Perform OS patching, configuration management, and automation using Ansible, Bash, and Python.
Maintain and integrate parallel and shared filesystems such as NFS, Lustre, and S3 object storage.
Handle user access, quota control, and secure network configurations in a multi-user environment.
Administer FlexLM license management systems.
Software, Containers & Build Frameworks
Work with container technologies such as Apptainer/Singularity, Podman, ENROOT, and Pyxis.
Manage scientific software builds (Ansys, Cadence, COMSOL, Matlab, Mentor, Synopsys) using tools like EasyBuild and environment modules via lmod.
Optimize deployments using Azure CycleCloud; experience with cloud-integrated compute clusters is a plus.
