Staff Infrastructure Engineer – Kubernetes Platform
About The Position
Our mission is simple: deliver seamless, secure, reliable, and resilient AI compute at scale. We've built a versatile cloud platform that eliminates infrastructure barriers, empowering builders to focus on innovation instead of fighting their stack. Because breakthrough AI should move at the speed of ideas, not infrastructure. We build and operate large-scale infrastructure platforms supporting high-performance AI workloads across multiple data centers. Our Kubernetes environments power core platform services and customer-facing workloads, and are evolving toward a managed, multi-tenant, multi-region platform model. We are looking for a Staff Infrastructure Engineer – Kubernetes Platform to own the design, evolution, and operational reliability of our Kubernetes control plane architecture. This role combines architecture and hands-on operational ownership, with a focus on building a scalable, multi-tenant platform comparable in maturity to managed Kubernetes offerings such as GKE or AKS. This is not a cluster administration role. You will be responsible for how Kubernetes operates as a platform across regions.
Requirements
- 7+ years of experience in infrastructure, platform engineering, or distributed systems
- Deep experience operating Kubernetes at scale in production environments
- Experience in CSP, hyperscale, or equivalent large-scale environments strongly preferred
- Proven experience scaling Kubernetes across: Multiple clusters, Multiple regions or data centers
- Strong understanding of Kubernetes internals: API server, Scheduler, Controller manager, etcd
- Experience designing or evolving: Control plane architectures, Multi-tenant cluster models
- Strong Linux systems expertise
- Deep troubleshooting ability across: Kubernetes, Container runtime, Networking stack
- Experience with CNI plugins (Cilium preferred)
- Strong understanding of: Networking and traffic patterns, Resource isolation and scheduling
Nice To Haves
- Experience with virtual cluster technologies (vcluster, Kamaji, or similar)
- Experience supporting GPU workloads in Kubernetes
- Familiarity with: NUMA-aware scheduling, Topology-aware workloads
- Awareness of RDMA and high-throughput networking environments
- Experience with observability platforms (Prometheus, Grafana, etc.)
Responsibilities
- Design and evolve Kubernetes control plane architecture across regions
- Define and implement multi-tenant cluster models, including shared control planes, virtual cluster approaches (e.g., vcluster, Kamaji)
- Drive transition from standalone clusters to regionally managed platform models
- Define standards for isolation boundaries, resource segmentation, policy enforcement
- Own the reliability and behavior of Kubernetes platforms in production
- Participate in on-call rotation and lead incident response
- Diagnose and resolve control plane instability, API server saturation, scheduling and resource contention issues
- Ensure consistent lifecycle management across clusters - provisioning, upgrades, scaling
- Design and implement strategies for regional scaling, multi-data center cluster deployments
- Ensure consistent behavior and reliability across environments
- Define cluster topology and failure domain strategies
- Design ingress and egress architectures at cluster level and regional level
- Troubleshoot and optimize pod-to-pod networking, north-south traffic flows, CNI behavior (Cilium preferred)
- Collaborate with network engineering on high-performance networking integration
- Improve observability across control plane components, cluster health and performance
- Define and implement resilience strategies aligned with platform goals
- Lead root cause analysis for production incidents
- Work closely with DevOps engineers (automation and CI/CD) and Infrastructure teams (compute, storage, networking)
- Align Kubernetes platform design with underlying infrastructure capabilities
