IT Systems & HPC Infrastructure Specialist 60% - contractor

Are you a Linux-savvy IT professional who thrives at the intersection of systems administration and High-Performance Computing (HPC)?

We are looking for a Part-Time IT Systems & HPC Infrastructure Specialist to manage our technical environment. While we have 30 employees who need standard support, our additional challenge lies in maintaining the high-performance compute farms and cloud-bursting capabilities that drive our engineering team.

Currently, these tasks are handled by our senior engineers; we are looking for a dedicated specialist to take over the tactical management of our local and cloud infrastructure, ensuring our compute-heavy workloads run reliably and securely, as well as helping enhance and maintain our standard office IT infrastructure.

Responsibilities

• HPC (High-Performance Computing) - Ensuring engineers have the compute and tools needed for their work.

• Compute Management: Manage and optimize job scheduling tools (SLURM, LSF-like) for heavy compute loads.

• Hardware Acceleration: Ensure optimal GPU access (both local and cloud-based).

• DevOps & Infrastructure - Automation, security, and the "invisible" backbone that keeps systems running reliably.

• Infrastructure Automation: Use Ansible to deploy, configure, and maintain on-premises servers (Proxmox/bare-metal) and cloud environments.

• Containerization & Data Pipelines: Facilitate data pipelines utilizing Kubernetes, Docker, and containers.

• Security & IAM: Manage identity and authentication (LDAP, SSSD, SAML) and maintain firewall rules (Fortinet).

• Data Integrity: Maintain a rigorous backup/snapshot regime and ensure all SaaS data (e.g. GitLab, Coda) is archived to the NAS.

• Business Continuity: Establish disaster recovery procedures and conduct security audits/log monitoring.

• Helpdesk & IT Operations - Supporting the human element and managing the physical office technology.

• User Support: Provide essential support for the ~ 30 users (troubleshooting hardware, app freezes, network latency).

• Endpoint Management: Deploy and maintain Operating Systems (Windows/macOS) and manage ESET/Google Admin consoles.

• Life Cycle Management: Onboarding/Offboarding employees and providing training on security/IT tools.

• Vendor Relations: Act as the technical point of contact for partners and third-party service providers.
