Job description

A genuinely hands-on HPC opportunity for an engineer who enjoys getting stuck into complex infrastructure.

This is an opportunity to join a technically ambitious environment where your Linux and HPC expertise will have an immediate impact. You'll be brought in to assess and improve an existing computational platform, while also helping keep the underlying infrastructure running reliably day to day.

You'll have the freedom to identify where things can be improved, make recommendations, and then get involved in delivering those changes.

Role Style & Setup

This is a hands-on consulting engagement, rather than a pure review or advisory assignment. You'll work alongside the existing Infrastructure team, balancing operational support with targeted improvement work.

You'll be expected to get under the bonnet of the environment, understand how it currently operates, identify areas holding it back, and turn those findings into practical improvements.

Key Responsibilities

• Assess and optimise the existing HPC environment, including compute, scheduling, storage and network performance
• Provide senior-level Linux administration and troubleshooting across the infrastructure
• Investigate performance, availability and capacity issues using monitoring and observability tooling
• Deliver infrastructure improvements through defined work packages and sprint-based activity
• Improve automation, reliability and operational processes across the platform
• Document findings, recommendations and technical changes for the wider team

Skills & Experience Required

• Strong commercial experience administering RHEL/Linux in demanding technical environments
• Proven HPC experience, ideally working with Slurm and distributed compute environments
• Experience with containers and/or virtualisation
• Strong automation capability using Ansible, Python and Bash
• Comfortable diagnosing complex infrastructure and performance problems
• Able to work independently and communicate technical findings clearly
