Our client is a highly respected global consulting and research organization that supports leading commercial enterprises, public sector institutions, and professional services firms. As part of a significant investment in AI infrastructure, they are expanding their internal high performance computing (HPC) and GPU capabilities to support next-generation machine learning and large language model (LLM) initiatives.
This is an exciting opportunity to join a small, highly skilled infrastructure team at a pivotal stage of growth. The successful candidate will play a key role in scaling a GPU environment from 8 to 32 NVIDIA H200 GPUs while helping shape the organization's long-term AI and HPC strategy.
The role is heavily project-focused, with approximately 85% dedicated to engineering, architecture, and platform development activities, and a smaller proportion supporting operational needs.
The Opportunity
You'll work at the intersection of traditional HPC, research computing, and modern AI infrastructure, supporting both analytical workloads and large-scale model training environments.
Key responsibilities include:
- Designing, deploying, and maintaining GPU-accelerated computing infrastructure
- Supporting large-scale AI/ML and LLM training environments
- Managing Linux-based HPC clusters and associated services
- Administering and optimizing parallel file systems, particularly IBM Spectrum Scale (GPFS)
- Managing NVIDIA GPU platforms, CUDA, cuDNN, NCCL, and related tooling
- Supporting resource scheduling through SLURM and related technologies
- Performance tuning for distributed and multi-GPU workloads
- Building automation, monitoring, reporting, and operational tooling
- Collaborating with researchers, data scientists, and technical stakeholders to translate business requirements into infrastructure solutions
- Evaluating emerging AI infrastructure technologies and recommending future platform enhancements
Required Experience
We're particularly interested in candidates who combine deep infrastructure expertise with an understanding of how end-users consume HPC resources.
Essential Skills
- Strong Linux systems administration background
- Experience supporting HPC or research computing environments
- Hands-on NVIDIA GPU infrastructure experience
- Strong experience with GPFS / IBM Spectrum Scale
- Familiarity with job schedulers such as SLURM, LSF, or similar
- Experience supporting distributed compute environments
- Ability to lead projects independently with minimal oversight
- Strong troubleshooting experience across compute, storage, networking, and hardware layers
- Excellent communication skills with the ability to explain complex technical concepts to non-technical stakeholders
Highly Desirable
- Experience supporting AI/ML infrastructure or LLM platforms
- Kubernetes and container orchestration experience
- MLOps tooling exposure (MLflow, Kubeflow, etc.)
- Experience tuning large model training and inference workloads
- Bright Cluster Manager
- Ansible
- Docker, Apptainer, or Singularity
- SAS platform experience alongside GPU/HPC expertise
Ideal Background
This role is particularly well suited to someone who:
- Has approximately 5-10 years of relevant infrastructure experience
- Is currently operating at a strong mid-level and ready for a senior step forward
- Can own and deliver significant technical projects independently
- Comes from an HPC, research computing, higher education, government, scientific computing, or technical enterprise environment
- Enjoys balancing infrastructure engineering with emerging AI technologies
Team & Culture
You'll join a close-knit team of experienced infrastructure specialists covering HPC operations, automation, applications, and platform engineering. The group operates in a highly collaborative remote-first model, with team members distributed across the United States. xhyhwjd
A notable area of planned growth is AI and LLM infrastructure expertise, making this a high-visibility hire with significant opportunity for progression and influence.
