GPU Cluster Engineer, Hardware Operations

About the role

Sciforium is an AI infrastructure company developing next-generation multimodal AI models and a proprietary, high-efficiency serving platform. We are looking for a dedicated Hardware Operations Engineer to own the physical health and foundational infrastructure of our GPU clusters. You will be the primary custodian of our compute hardware, responsible for everything from data center vendor coordination up to the base Linux OS layer, ensuring our research and product teams have a stable, secure, and fully operational physical environment to run their demanding compute workloads on.

Responsibilities

• System Health & Hardware Reliability
  • Serve as the primary point of contact for physical system outages, hardware failures, and network interruptions to minimize downtime.
  • Proactively monitor hardware health, including GPU thermals, power draw, and physical system loads, catching anomalies before they impact active workloads.
  • Work closely with data center facility staff and third-party hardware vendors to coordinate RMA processes, physical repairs, part replacements, and routine maintenance.
  • Rack, cable, and lead the physical bring-up of new GPU nodes, ensuring power and network connectivity are fully integrated into the existing cluster.
• Linux & Network Administration
  • Install, patch, and maintain Linux operating systems (Ubuntu/CentOS/RHEL) across the cluster bare-metal servers.
  • Configure and maintain edge and internal networking, including firewalls, VPNs, and strict SSH access controls to secure our infrastructure.
  • Administer LDAP/Active Directory for centralized user authentication and ensure network storage systems (NFS/GPFS/Lustre) are reliably mounted and properly permissioned.

Requirements

• Must-Haves:
  • 3+ years of experience in Linux Systems Administration (deep knowledge of boot processes, systemd, disk management, etc.).
  • Strong background in server hardware troubleshooting, specifically within high-density environments (power, cooling, PCIe topologies).
  • Experience managing networking security (VPNs, iptables/firewalld, VLANs) and directory services (LDAP/FreeIPA/Active Directory).
  • Proficiency in Bash scripting for essential system automation.
• Nice-to-Haves:
  • Experience using configuration management tools like Ansible, SaltStack, or Terraform for OS provisioning.
  • Familiarity with data center operations, cooling requirements for high-TDP accelerators (like NVIDIA B200 or AMD MI355x).

Benefits

• Medical, dental, and vision insurance
• 401k plan
• Daily lunch, snacks, and beverages
• Flexible time off
