What you will do

• Design, deploy, and operate production Slurm clusters on bare-metal and virtual machine GPU infrastructure, including high availability, authentication, accounting, and live upgrades.
• Build topology-aware scheduling for InfiniBand, RoCE, and NVLink GPU fabrics, validating placement quality through NCCL bandwidth and multi-node training tests.
• Own multi-tenant scheduling policies covering accounts, associations, partitions, QOS, fairshare, preemption, reservations, and TRES limits with fail-closed authorization.
• Lead Slinky slurm-operator adoption on Kubernetes and evaluate slurm-bridge for co-scheduling Kubernetes workloads through Slurm.
• Automate elastic GPU capacity, containerized job runtimes, cluster health checks, rack acceptance testing, provisioning, observability, accounting, and billing integration.
• Write runbooks and customer documentation, support enterprise onboarding and escalations, and mentor platform engineers.

Requirements

• 8+ years of HPC, systems, or cloud infrastructure engineering experience, including 4+ years operating production Slurm clusters at 100+ GPU-node scale.
• Deep hands-on experience with Slurm configuration, scheduling policies, accounting, authentication, REST APIs, and live version upgrades.
• Strong knowledge of NVIDIA GPU infrastructure, DCGM, MIG, InfiniBand/RoCEv2, GPUDirect RDMA, NCCL tuning, and GPU failure diagnosis.
• Production Kubernetes experience and hands-on exposure to Slinky slurm-operator, slurm-bridge, CoreWeave SUNK, or Nebius Soperator.
• Experience with bare-metal provisioning, firmware lifecycle management, virtualized compute, Terraform, Ansible, and shared storage such as Lustre, GPFS, WEKA, VAST, or NFS.
• Proficiency in Python and Bash, plus clear written and verbal English communication for enterprise customer engagement.
