At EY, we’re all in to shape your future with confidence.

We’ll help you succeed in a globally connected powerhouse of diverse teams and take your career wherever you want it to go. Join EY and help to build a better working world.

We are seeking AI Systems Engineers to build and operate the foundational substrate that powers EY’s AI-native platform. This role owns the infrastructure and cloud-native platform layers of the Hybrid AI Multi-Environment Runtime (HAI), from bare-metal and GPU infrastructure through Kubernetes, cluster fabric, and multi-tenant scaling. You will be responsible for building and managing EY Fabric environments across cloud, on-prem, edge, and air-gapped targets.

This is the substrate on which EY Agentic AI capabilities run. This role is ideal for a full-stack infrastructure leader who is equally comfortable with bare-metal and GPU systems and production Kubernetes at scale, who treats reliability and portability as non-negotiable in regulated client contexts, and who understands that the substrate is a product in its own right, measured by the velocity, safety, and portability it unlocks for every team building above it.

• Own the cluster & cloud-native platform: compute, Kubernetes and scheduling, cluster fabric/networking, multi-tenancy, and distributed compute, as the substrate for Agentic AI workflows and tooling.

• Own the infrastructure foundation: Ubuntu/OS, BMC/bare-metal, DPU architecture, and NVAIE (GPU/Network/DCGM), ensuring the physical and virtual bedrock is provisioned, patched, and production-ready.

• Stand up and manage EY Agentic AI environments across cloud (EKS/AKS/GKE), on-prem AI Factory (RKE2/NVAIE), edge (K3s), and air-gapped deployment modes, maintaining one consistent stack contract across all targets.
• Deliver foundational platform capabilities such as Infrastructure Management, Kubernetes & Scheduling, and Cluster Fabric Management, so downstream runtime, data, and execution services can run safely and consistently.
• Own cluster lifecycle, autoscaling, GPU pooling/virtualization, and multi-tenancy boundaries (vCluster/Crossplane/Karpenter), providing isolated, elastic capacity per tenant and engagement.
• Own secure execution and inference: Ray Serve, vLLM/NIM/Triton, and NVIDIA Dynamo, with sandboxed execution (gVisor/Firecracker for hosted, NVIDIA OpenShell/vNode for on-prem) for isolated, safe model execution.
• Own cognitive and routing: Envoy AI Gateway, semantic routing (vLLM-SR), model/prompt selection, and streaming response handling — directing each request to the right model under the right constraints.
• Collaborate with DevOps Engineers on deployment and delivery of the platform itself: CI/CD/CV (ArgoCD), infrastructure‑as‑code / GitOps (Helm/OpenTofu), so environments are reproducible and drift‑free.
• Own backup, disaster recovery, and cross‑environment replication for high availability (Velero, CloudNativePG, Cilium ClusterMesh), along with patching and platform supply‑chain hygiene.
• Ensure the substrate is modular and swappable, so components can be replaced without rewriting consumers, minimizing vendor lock‑in while preserving the stack contract.

• Deep expertise in cloud‑native platform engineering (Kubernetes, networking, multi‑tenancy at scale) and low‑level infrastructure and systems engineering (bare‑metal, GPU, DPU).
• Advanced understanding of how compute, networking, storage, and scheduling interact to form a reliable, portable substrate.
• Comfortable operating across cloud, on‑prem, edge, and air‑gapped environments simultaneously, with a portability‑first mindset.
• Strong command of AI gateways, semantic routing, and model/prompt selection under latency and cost constraints.
• A passion for ensuring reliability, repeatability, and reduction of operational toil through automation and infrastructure‑as‑code.
• Ability to define and honor clean ownership boundaries with adjacent trust, data, and runtime teams.
• Strong communicator able to explain infrastructure tradeoffs to engineers, architects, and leadership.
• Natural product‑ownership orientation toward foundational platforms, measured by the downstream velocity and reliability they enable.

• Bachelor’s or Master’s degree in Computer Science or related technical field.
• 8+ years building or operating enterprise infrastructure, cloud platforms, or large‑scale Kubernetes environments, including hands‑on systems depth.
• Hands‑on expertise with Kubernetes distributions (RKE2, EKS/AKS/GKE, K3s) and full cluster lifecycle management.
• Deep experience with bare‑metal, cloud, hybrid, on‑prem, and ideally air‑gapped deployment models.
• Strong grounding in cluster networking (Cilium/service mesh/CNI), storage, and multi‑tenancy isolation.
• Experience with GPU infrastructure and scheduling (NVAIE/DCGM, GPU operators, virtualization/MIG).
• Experience with infrastructure‑as‑code and GitOps tooling (Terraform/OpenTofu, Helm, ArgoCD, Crossplane).
• Proven track record operating production infrastructure under compliance, security, or regulatory constraints.
• Ability to work effectively with security, architecture, product, and delivery teams.

• Experience supporting AI/ML and GPU‑intensive workloads (GPU virtualization, MIG, AI workload scheduling).
• Experience with multi‑tenant platforms and tenancy isolation at scale (e.g., vCluster).
• Experience with disaster recovery, backup, and cross‑environment replication tiered by RPO/RTO.
• Familiarity with distributed compute and batch orchestration (Kueue, Slurm/Slinky, Ray, OpenMPI).
• Background in platform or SRE roles where success is measured by downstream team velocity, reliability, and portability.
• Exposure to regulated delivery environments (financial services, tax, healthcare, risk).
