About the role

  • Enforce fail-closed defaults: an unresolved tenant identity or an empty entitlement set must deny, never degrade into unrestricted access.
  • Qualifications 8+ years in HPC, systems, or cloud infrastructure engineering, including 4+ years operating production Slurm clusters at 100+ GPU-node scale with real users and service-level commitments.

Responsibilities

  • Slurm cluster architecture and lifecycle - Design, deploy, and operate production Slurm clusters on bare metal and VMs: slurmctld/slurmdbd high availability, slurmrestd, configless slurmd, SACK/MUNGE and JWT authentication, and rolling version upgrades on live clusters without losing running jobs.
  • Topology-aware scheduling for GPU fabrics - Model the physical fabric in topology.conf - topology/tree for rail-optimized InfiniBand/RoCE designs and topology/block for NVLink domains such as GB200/GB300 NVL72 - and prove placement quality with NCCL bandwidth and multi-node training validation rather than assumption.
  • Multi-tenant scheduling policy - Own the account/association tree, partitions, QOS, fairshare, preemption, reservations, and per-tenant TRES limits.
  • Slinky on Kubernetes - Lead implementation of the Slinky slurm-operator, including its NodeSet, LoginSet, Accounting, RestAPI, and Token custom resources, cert-manager and Helm-based delivery, shared parallel-storage mounts, and login pods running sackd/sshd.
  • Evaluate and pilot slurm-bridge for co-scheduling Kubernetes Pods, PodGroups, Jobs, JobSets, and LeaderWorkerSets through the Slurm scheduler, and document its constraints - notably exclusive whole-node allocation - before any customer exposure.
  • Container and job runtime - Operate Pyxis/Enroot and OCI/containerd job paths with correct gres.conf, cgroup v2 device constraints, and CUDA_VISIBLE_DEVICES behavior; support MPI/PMIx, module/Spack environments, and customer-supplied images.
  • Own burn-in and acceptance testing for every new rack before it carries paid work.
  • Automation and infrastructure as code - Deliver clusters through Terraform/Ansible, golden images, and bare-metal provisioning (PXE, Redfish, IPMI) so that a cluster build is reproducible, reviewable, and auditable rather than hand-tuned.
  • Multi-tenant security discipline: derives tenant scope from a verified identity rather than client-supplied fields, designs authorization to fail closed, and treats isolation across accounts, namespaces, storage, and networks as a hard requirement.
