The role

We are seeking a highly skilled Senior Kubernetes Engineer to join our Platform Engineering function in Dallas.

In this role, you will design, implement, and optimise GPU-accelerated container platforms at scale, enabling high-performance workloads (AI/ML, HPC, LLM training) across hybrid or on-prem environments.

You will have deep expertise with both NVIDIA and Kubernetes ecosystems, including GPU scheduling, device plugins and custom operators.

Key responsibilities of the role include:

• Architecting and operating Kubernetes clusters optimised for GPU workloads, leveraging NVIDIA GPU Operator, Network Operator and DCGM

• Developing, deploying and maintaining custom Kubernetes operators and controllers to automate infrastructure services

• Integrating NVIDIA device plugins, Multi-Instance GPU (MIG) and GPU sharing features into the scheduling layer

• Optimising GPU utilisation and job placement through scheduler extensions, such as kube-scheduler plugins, Slurm and Volcano

• Collaborating with HPC, ML and DevOps teams to ensure multi-tenant, high-throughput cluster performance

• Driving observability and telemetry integrations using Prometheus, Grafana, DCGM Exporter and OpenTelemetry

• Implementing secure multi-user and multi-namespace GPU isolation, with RBAC and policy enforcement, such as OPA or Gatekeeper

• Maintaining CI/CD pipelines for Kubernetes infrastructure using GitOps, ArgoCD and FluxCD

• Contributing to infrastructure-as-code, using Terraform, Helm, and Kustomize

• Participating in performance tuning, incident response and production readiness reviews

Who are we looking for?

The ideal candidate will have the following skills and experience

• Extensive experience with Kubernetes in production-grade environments and working with NVIDIA and Kubernetes, including GPU Operator, device plugin, NVML, MIG and DCGM

• Proficiency in Go or Python for operator development and Kubernetes controller logic

• Deep understanding of Kubernetes internals, including CRDs, RBAC, custom controllers and scheduler extensions

• Experience with GPU-intensive workloads, for example for LLMs, training pipelines and scientific computing

• Hands-on experience with Helm, Kustomize and GitOps workflows

• Familiarity with CNI plugins, especially NVIDIA CNI and Multus

• Experience with monitoring GPU metrics and cluster health using Prometheus and DCGM Exporter

The following is beneficial:

• Knowledge of container runtimes with CRI-O, containerd and NVIDIA Container Toolkit

• Contributions to open-source projects in the Kubernetes or NVIDIA ecosystem

• Preferred experience working with cilium or CNI plugins

Why should you apply?

• Market-leading compensation plus annual discretionary bonus

• Lunch provided in the office (via GrubHub)

• Informal dress code and excellent work/life balance

• Excellent paid time off allowance of 25 days

• Sick days, military leave, and family and medical leave
