(GPU) Infrastructure Engineer

Orcrist is building a next generation data intelligence platform using cutting-edge technologies.

We’re handling petabyte-scale data with sub-second queries.

Our product is a Kubernetes-based platform delivered as B2B Saa S or as a self-hosted on-prem solution, including air-gapped deployments.

We enable customers across defense, law enforcement, and enterprise to turn mission-critical data into actionable intelligence.

Our Platform team owns the infrastructure that powers every deployment, from the metal up.

• Infrastructure Engineer – Platform
• Role

Kubernetes runs on something, and that something is yours.

You’ll own the layer beneath our platform: bare-metal GPU servers, operating systems, networking, and storage across on-prem and fully air-gapped sites.

You design, build, and operate GPU server fleets and the NVIDIA software stack, then partner with our SRE and ML teams to deliver fast, reliable on-prem inference.

Some of this work is hands‑on at customer sites, where you size, rack, and commission self‑contained server environments that run with no internet uplink.

• What you’ll do
• Design, size, provision, and operate bare-metal GPU server fleets across on‑prem and air-gapped environments (firmware/BIOS, BMC via Redfish/IPMI, OS, drivers) with zero‑touch provisioning (PXE/i PXE, MAAS/Metal3/Tinkerbell) and automation (Ansible/Salt, Terraform/Pulumi).
• Own the NVIDIA GPU stack end to end: drivers, CUDA, GPU Operator, Container Toolkit, MIG, and DCGM, tuned for inference throughput, latency, and utilization.
• Build the bare‑metal substrate Kubernetes runs on: node lifecycle, container runtime, GPU device plugins, node feature discovery, and kernel/NUMA tuning.
• Engineer data‑center networking and resilient storage (VLANs/switching, RDMA, Ceph/ZFS/NVMe) sized to scale without replacing the core, with encryption at rest.
• Partner with ML and MLOps on on‑prem inference serving (Triton, KServe, v LLM): model deployment, GPU scheduling and sharing, and performance tuning.
• Plan and run on‑site build‑outs: rack integration, power/UPS and cooling sizing, commissioning, capacity planning, runbooks, and operator handover.

About You

• 5+ years in bare‑metal, HPC/GPU, data‑center, or systems infrastructure engineering, with hands‑on ownership of physical and compute infrastructure.
• Strong bare‑metal Linux (RHEL/Rocky/Ubuntu): firmware, BMC, PXE, kernel and storage tuning, plus solid networking and storage fundamentals.
• Real experience with the NVIDIA GPU stack (drivers, CUDA, GPU Operator, MIG, DCGM) and serving GPU models in production.
• Comfortable operating in air‑gapped or on‑prem environments and traveling to customer sites for builds and deployments.
• Documentation‑focused, methodical, and calm during hardware incidents.
• Ideally with a B driver's license.
• Eligible to work in Germany.
• Nice‑to‑haves
• German language (B1+)
• NVIDIA DGX/HGX or Slurm experience
• Infini Band/RDMA fabrics, and inference optimization (Tensor RT-LLM, v LLM, quantization)
• Certifications such as NVIDIA NCP-AIO, Red Hat RHCSA/RHCE, or CKA/CKS.
• Field‑engineering experience and familiarity with secure or regulated deployment environments.

What We Offer

• Modern architecture & stack.
• Remote‑first in Germany with occasional team events in Berlin.
• Home office budget and great equipment.
• 30 days vacation.
• Direct impact on critical missions across private and public‑sector customers.
