HPC Data Centre SME

We are looking for an experienced High-Performance Computing (HPC) / Data Centre Subject Matter Expert (SME) with a strong cyber security background to support the design, build, and operation of secure, high-availability compute environments. You’ll work closely with technical and non-technical stakeholders across architecture, engineering, operations, and security teams.

• Active UK security clearance
  : SC / DV / eDV
• Or equivalent high-level access such as UKIC / STRAP (where applicable)
• Must be eligible to work in the UK and able to work in controlled environments (site-based / restricted areas as required)

• Provide SME-level input into HPC/data centre architecture
  , including compute, storage, and high-speed networking.
• Support delivery of resilient, scalable, and performance-optimised environments for demanding workloads.
• Lead / contribute to capacity planning
  , performance tuning, benchmarking, and workload optimisation.
• Define and improve operational processes for availability, recoverability, monitoring, and incident response.
• Work with engineering teams to drive best practice across build, automation, and lifecycle management
  .

• Build security into HPC and data centre designs (e.g., segmentation, hardening, privileged access, logging).
• Work with security teams to implement and maintain security controls without impacting performance.
• Support vulnerability management and remediation across infrastructure and operating systems.
• Help integrate security monitoring (e.g., log collection, alerting) into the wider operational model.
• Contribute to security-related documentation (designs, runbooks, procedures).
• Proven background as an HPC / data centre SME (architecture and/or operations).
• Strong cyber security experience in secure or regulated environments
  .
• Demonstrable knowledge across:
• HPC platforms (cluster design, schedulers, compute architectures, accelerators where relevant)
• High-performance storage concepts (throughput/IOPS, parallel file systems, tiering)
• Data centre networking (high bandwidth/low latency, routing/switching fundamentals, segmentation)
• Security fundamentals (system hardening, identity and access, audit/logging, secure remote access)
• Experience producing clear technical documentation (HLD/LLD, SOPs, runbooks).
• Comfortable engaging stakeholders from hands‑on engineering through to senior technical leaders.
• Automation / IaC exposure (e.g., Ansible, Terraform) in infrastructure environments.
• Experience with GPU/accelerated compute stacks and performance engineering (where relevant).
