About the role

Lead IT Engineer responsible for owning and evolving the HPC and IT infrastructure, providing hands-on support, mentoring junior engineers, and ensuring scalable, secure, and efficient IT operations for a physics AI company.

Responsibilities

  • Own and evolve our HPC environment: cluster administration, job scheduling (e.g., Slurm/PBS/LSF), performance tuning, and capacity planning for compute-heavy engineering workloads.
  • Experience with Entra ID Governance: Access Reviews, Identity Protection, Privileged Identity Management (PIM) at scale.
  • Provide hands-on IT support across the company with an automation-first mindset
  • Mentor and develop junior IT/support engineers, building a culture of ownership and technical rigor rather than ticket-closing.
  • Act as an escalation point for complex or high-priority issues across HPC, dev tooling, and general IT support.
  • Configure, support and improve developer tooling (e.g. Github Actions/Workflows, JFrog, Chainguard)

Qualifications

  • 7–10 years of experience in IT infrastructure, systems administration, or HPC support, with at least 2–3 years in a lead or senior technical role.
  • Hands-on experience managing HPC infrastructure including cluster administration, job schedulers, and performance tuning for CPU/GPU workloads.
  • Experience with compliance frameworks (e.g. SOC 2, ISO 27001) and able to translate control requirements into actual technical implementation (access reviews, logging, encryption, change management).
  • Strong Linux administration skills, plus comfort supporting a mixed Linux/macOS/Windows environment typical of an engineering org.
  • Experience supporting developer tooling and workflows including CI/CD systems, version control, license management, and internal engineering platforms.
  • Experience in cloud-native environments across multiple cloud vendors.
  • Strong experience designing and setting up zero trust environments.
  • Strong networking fundamentals and hands-on operational experience: routing and switching, segmentation, firewalls, VPN, enterprise wireless, DNS/DHCP/IPAM and TLS/PKI, with confident packet-level troubleshooting.
  • Excellent structured troubleshooting: isolating layers, proving the cause, preventing recurrence, and teachingmethodology to others.
  • Strong automation and scripting ability (Python, Bash, PowerShell) with infrastructure as code and configuration management as default working methods.
