Jobbeschreibung

• Own the end-to-end platform architecture through architecture proposals, high-level and low-level designs, reviews, and maintenance of the baseline
• Lead and line-manage a distributed team of about twelve engineers across backend, frontend, DevOps, QA, and documentation
• Establish engineering standards, conduct code and design reviews, manage release gates, hold one-to-ones, and provide growth and performance input
• Design, build, and operate a managed Slurm service for research users
• Own controller and accounting, partitions and login nodes, node onboarding, driver and CUDA baselines and upgrades, stalled-job and node-health detection, drain and autohealing, storage visibility, identity, and isolation
• Own Kubernetes cluster bootstrap and lifecycle on partner-provided bare metal
• Implement NVIDIA GPU Operator and Network Operator, VM-based GPU isolation with KubeVirt and VFIO, upgrades, backup and recovery, and node replacement
• Own managed inference architecture, including serving, multi-GPU and multi-node parallelism, autoscaling, request routing, endpoint reliability, and confidential-compute-capable capacity
• Establish metrics, logging, alerting, and SLOs across the control plane, GPU fleet, and application tiers
• Lead incident response, post-incident reviews, and development of a sustainable on-call model
• Serve as the primary technical interface to infrastructure partners and vendors
• Translate requirements into written specifications and acceptance tests, manage escalations, and contribute to capacity planning and hardware sourcing
• Work with research, model-training, and product teams to translate workloads into platform requirements and broker capacity
• Complete the platform team and set the technical bar for new engineers

Requirements

• Eight or more years of hands-on engineering experience
• At least three years leading teams that build and operate infrastructure platforms other teams depend on
• Bachelor's or Master's degree in computer science or engineering, or equivalent practical experience
• Hands-on experience running Slurm at scale, including slurmctld, slurmdbd, partitions, QoS, priority, accounting, prolog and epilog, node health scripting, and upgrades with jobs on the system
• Experience operating an HPC or GPU training cluster for a research population is ideally preferred
• Experience operating NVIDIA GPU fleets on bare metal, including NVIDIA driver and CUDA lifecycle, Fabric Manager, NVSwitch, DCGM, MIG, node burn-in, and acceptance
• Experience with InfiniBand, subnet configuration, RDMA, SR-IOV, and diagnosing multi-node NCCL performance problems
• Deep Linux systems knowledge, including kernel modules, drivers, PCIe passthrough, vfio-pci, cgroups, namespaces, and performance tuning
• Production Kubernetes operations experience, including control plane, upgrades, CNI, CSI, operators, custom controllers, and multi-tenancy design
• Experience with HPC storage and data movement, including VAST, Lustre, NFS, node-local NVMe caching, and distributing large model weights and datasets
• Experience with Prometheus, Grafana, Loki or equivalents, SLOs, incident response, and post-incident review
• Working fluency in JavaScript and Node.js sufficient to review control-plane, CLI, and worker services and make architecture decisions
• Experience shipping a platform with real users, such as a multi-tenant IaaS/PaaS or research computing service
• People management across time zones, cross-track review, written architecture decisions, and partner/executive communication
• Excellent written and spoken English
• Based between UTC and UTC+5:30
• Desirable: Slurm operators on Kubernetes or Kubernetes-native schedulers
• Desirable: modern serving stacks such as vLLM, SGLang, and TensorRT-LLM
