Your new company

Join a pioneering organisation at the forefront of AI and High Performance Computing (HPC) infrastructure. With a strong focus on innovation and ethical computing, this company is building scalable, GPU-optimised environments that support cutting-edge research and enterprise workloads.

Your new role

This is a fully remote, hands-on technical role where you'll lead the design, deployment, and optimisation of large-scale AI and HPC clusters.

You'll be responsible for creating detailed technical designs, including hardware specifications, data centre layouts, cabling, and power/cooling requirements.

You'll install and tune Linux-based operating systems, configure SLURM job schedulers, and optimise high-speed networking technologies such as Infiniband and RoCE.

The role also involves scripting and automation (Ansible, Terraform), troubleshooting complex distributed systems, and mentoring junior engineers and service teams.This is an ideal opportunity for someone who thrives in project-led infrastructure work and wants to shape the future of AI and HPC platforms.

Proven experience designing, deploying, and scaling large HPC environments (hundreds to thousands of nodes).

SLURM Scheduler Configuration:
Deep understanding of SLURM partitions, priorities, and resource management.

Networking:
Strong knowledge of high-performance networking (Infiniband, RoCE, RDMA) and troubleshooting interconnectivity issues.

Linux Systems:
Advanced Linux administration skills, including performance tuning and OS-level troubleshooting.

Storage Systems:
Experience with parallel/distributed file systems (e.g. Lustre, Ceph, WEKA, VAST).

Automation & Scripting:
Proficiency in Bash, Python, and tools like Ansible and Terraform for deployment and maintenance.

Monitoring & Resilience:
Experience implementing monitoring solutions and ensuring high availability and security compliance.

Documentation & Mentoring:
Excellent written communication skills and a collaborative approach to mentoring and knowledge sharing.

Desirable Experience

  • Containerisation in HPC (Singularity, Docker, Apptainer)
  • Familiarity with AI/ML workflows, GPU-aware MPI, and NVLink
  • Experience in cloud, academic, or research environments
  • Vendor hardware validation and data centre planning

What you'll get in return

  • Share options.
  • Unlimited holiday policy.
  • 100% Remote working.
  • Fantastic opportunities to develop - they make a habit of promoting in-house.
  • A great team with a passion for working collaboratively.
