Pay Rates:Umbrella Rate: £500-650/day (via a Hays approved umbrella company).Hours: 37.5 hours a week. Monday - Friday.Time: 9:00 AM - 5:30 PM HPC Containerization & HPC Expert - Job Description Role OverviewThis role provides high-level consultancy and firsthand engineering expertise to modernise High-Performance Computing (HPC) environments with a focus on containerisation of HPC and HPC/ML workloads, cluster optimisation, and MPI-aware workflows. Responsibilities include assessing the existing HPC infrastructure, advising on best-practice for container strategies, and delivering technical recommendations based on real workloads., The ideal candidate will collaborate with the customer to assess existing HPC infrastructure and workloads through various customer workshops and interviews, to identify: HPC Environment Assessment & Optimization Conduct rapid reviews of existing HPC infrastructure, including Beowulf clusters,Slurm job schedulers, workflow execution patterns, and key use cases. Analyze current HPC/ML workloads and identify performance constraints, containerization opportunities, and runtime optimization options.

HPC Containerization Strategy:

Produce a strategy for MPI-optimized container images using tools such as Apptainer/Singularity (SIF), OpenMPI, Podman, and Buildah. As part of the report's findings, they outline repeatable, secure build pipelines for HPC workloads. Identify in the report opportunities to align container platforms with HPC orchestration requirements (batch, interactive, scientific workflows).

Technical Workshops, Stakeholder Engagement

Lead technical discussions, workshops, and training sessions to upskill engineering and research teams on containerization and HPC best practices. Produce concise written reports outlining the recommendations and findings, use cases, future strategy, HPC market view along with, next steps, and architectural patterns.

Have a good understanding of Slurm scheduling, MPI job patterns,JupyterHub/JupyterLab for data-science workflows, GPU scheduling tools such as Run:AI, and SDLC practices tailored to research/HPC environments., Proven background in high-performance computing, including hands-on use of Beowulf-style cluster environments. Strong practical knowledge of Slurm job scheduling and MPI job optimization. Demonstrated experience with MPI-aware container technologies (Apptainer/SIF, OpenMPI, Podman,Buildah). Ability to run structured interviews, technical workshops, and cross-team engineering sessions. Experience supporting typical HPC,ML and scientific workloads. SC Clearance and UK-only nationality is frequently required for HPC consulting roles within defense/aerospace environments.

Desirable Experience:

Knowledge of CFD software (e.g., OpenFOAM). Familiarity with Kubernetes or Singularity as an HPC runtime, GPU slicing, and image lifecycle governance. Experience contributing written outputs such as market assessments of HPC container technologies.

Key Requirements:Candidates must be active SC cleared
