AI Infrastructure Engineer - LCYL

AI Infrastructure Engineer 5 days, Mon - Fri 8.30am to 5.30pm Salary: $5,000 to $7,000 Location: 2 Kaki Bukit Ave 1, Singapore 417938 Job scopes: Compute & Cluster Management • Architect, configure, and maintain high-density multi-GPU compute clusters (e.g. NVIDIA HGX/DGX architectures). • Implement and manage container orchestration platforms (Kubernetes, Slurm, or Ray) optimized for AI/ML distributed workloads. • Monitor GPU health, telemetry, utilization, and thermals; minimize idle compute time and prevent single-node bottlenecks. High-Performance Networking & Storage • Design and optimize low-latency, lossless network fabrics supporting distributed training (InfiniBand, RoCE v2, NVLink, spine-leaf topologies). • Configure and scale high-throughput parallel file systems and object storage (e.g. Lustre, GPFS/IBM Spectrum Scale, Ceph, MinIO, NVMe-oF) to feed high-speed data pipelines. Automation & Infrastructure as Code (IaC) • Build and manage automated deployment pipelines using Terraform, Ansible, Helm, or Pulumi. • Maintain standard golden images, Linux OS tuning (kernel parameters, NUMA node binding, GPU drivers, CUDA/cuDNN libraries), and firmware updates. Operations, Observability & Performance • Set up end-to-end monitoring, alerting, and metrics dashboards (Prometheus, Grafana, DCGM exporter, NVIDIA System Management Interface). • Partner with AI/ML engineering teams to diagnose network bottlenecks, NCCL communication latency, and I/O wait states during distributed training jobs. • Lead incident response, root-cause analysis (RCA), and disaster recovery plans for mission-critical AI environments. Requirements: • Operating Systems: Deep expertise in Linux systems administration, kernel tuning, and shell scripting (Bash/Python). • Accelerated Compute: Strong understanding of GPU hardware architectures, CUDA runtimes, and PCIe/NVLink topologies. • Orchestration & Workload Scheduling: Hands-on experience with Kubernetes (GPU operator, device plugins) and/or HPC schedulers (Slurm, Run:ai, Ray). • High-Speed Networking: Proven experience with RDMA (RoCE v2 /InfiniBand), PFC (Priority Flow Control), and ECN configurations. • Storage Systems: Familiarity with high-IOPS, low-latency shared storage architectures for AI datasets and model checkpoints. • Automation: Proficiency in Infrastructure as Code (Terraform) and configuration management (Ansible). • Bachelor’s Degree in Computer Science, Information Technology, Computer Engineering, or equivalent practical experience. • 3–6+ years of hands-on experience in infrastructure engineering, high-performance computing (HPC), DevOps, or cloud infrastructure. • Relevant certifications are a plus (e.g., CKA/CKAD, NVIDIA Certified Associate/Professional, AWS/Azure/GCP Solutions Architect).
