About the Role

We're looking for a Senior HPC Support Engineer to join our fast-growing team, focused on enabling and optimising HPC and AI workloads on GPU-accelerated infrastructure.

You’ll work directly with customers solving some of the most complex problems in AI, helping them troubleshoot and optimize performance in compute-intensive, distributed environments.

This is a hands-on role requiring deep technical acumen, exceptional problem-solving ability, and comfort working across a diverse set of technologies including GPUs (NVIDIA and AMD), InfiniBand networking, and orchestration systems like Slurm.

What You’ll Be Doing

• Provide expert-level support for customer HPC and AI workloads running in production.
• Troubleshoot complex system-level issues across networking, storage, containers, and GPUs.
• Collaborate with engineering and vendor partners to resolve hardware/software compatibility and performance issues.
• Analyse distributed workloads and assist with tuning of MPI-based applications.
• Develop internal tools and automation to improve support workflows.
• Contribute to documentation and knowledge-sharing initiatives.

• Experience with GPU compute platforms (NVIDIA and/or AMD) and associated libraries.
• Familiarity with MPI libraries (e.g., OpenMPI), InfiniBand, and high-speed Ethernet networking.
• Solid Linux administration skills and troubleshooting experience.
• Working knowledge of HPC container runtimes (e.g., Singularity, Apptainer).
• Exposure to provisioning and automation tools (e.g., Ansible, PXE, Terraform).
• Experience with monitoring tools such as Prometheus, Grafana, and DCGM.
• Understanding of GPU/accelerator toolchains like CUDA or ROCm.
• A proactive, customer-first mindset with strong communication skills.
• Ability to work effectively in both individual and team settings.
• Comfort operating in fast-paced, ambiguous, high-growth environments.

Nice to have

• Experience with OpenStack and troubleshooting infrastructure in cloud environments.
• Kubernetes expertise, particularly in HPC or AI workload contexts.
• Familiarity with distributed file systems and advanced storage configurations.
• Understanding of GPU virtualization and multi-tenant HPC architecture.
• Exposure to machine learning frameworks and AI optimization workflows.
• Scripting skills in Python, Bash, or similar for automation and tooling.

Personal Attributes

• Proactive and self-motivated, with a strong sense of ownership.
• Thrives in a fast-paced, dynamic, and high-growth environment.
• Collaborative team player with a passion for delivering outstanding candidate and stakeholder experiences.
• Strong attention to detail and documentation skills.
• Excellent communication skills, both written and verbal.
• A self-starter mindset with a “see a problem, fix a problem” mentality.
