Software Engineer – Cloud Infrastructure

San Francisco, Remote. Posted 3 months ago

The role

You will own the architecture and evolution of the cluster platform for a GPU-accelerated AI inference cloud. This includes designing cluster connectivity, extending Kubernetes, and managing the network path for inference traffic.

What you will do

  • Own the architecture of multi-cluster, multi-tenant Kubernetes fleet.
  • Extend Kubernetes with custom controllers, operators, and CRDs.
  • Design GPU scheduling and capacity strategy.
  • Build autoscaling for inference traffic.
  • Own the Kubernetes network data plane including CNI, IPAM, DNS, ingress, and load balancing.
  • Design cross-AZ, cross-region, and cross-cluster connectivity.
  • Debug production network issues.
  • Define SLOs for platform-critical systems and lead post-incident hardening.
  • Deliver infrastructure as code with Terraform, Helm, and GitOps.
  • Partner with inference engine, platform, SRE, and security teams.

Required qualifications

  • 5+ years designing, building, and operating large-scale Kubernetes infrastructure in production.
  • Bachelor’s or Master’s degree in Computer Science, Computer Engineering, Electrical Engineering, or equivalent.
  • Proven experience operating large-scale, high-traffic network services in production.
  • Deep understanding of Kubernetes internals: API server, scheduler, controller loops, kubelet, and etcd.
  • Strong command of Kubernetes and cloud networking: CNI, kube-proxy/eBPF datapaths, DNS, load balancing, service mesh, and VPC routing.
  • Proficiency with AWS, Terraform, Helm, and Ansible.
  • Programming skills in Go or Python.
  • Strong debugging skills across distributed systems, containers, and the Linux networking stack.
  • Clear written and verbal communication.

Nice to have

  • Large-scale Kubernetes operations in a high-traffic domain such as gaming, e-commerce, or public cloud.
  • Cilium and eBPF, including kube-proxy replacement or upstream contributions.
  • Cluster provisioning and lifecycle management with Kubespray or similar Ansible-based tooling.
  • GPU orchestration: NVIDIA GPU Operator, device plugins, or Dynamic Resource Allocation (DRA).
  • High-performance networking for distributed workloads: RDMA/RoCE, InfiniBand, EFA, SR-IOV, or NCCL tuning.
  • Multi-cloud, hybrid-cloud, or bare-metal Kubernetes operations.
  • Contributions to Kubernetes, Cilium, Istio, or other CNCF projects.

Benefits

  • Flexible working hours
  • Daily lunch and dinner provided
  • unlimited snacks and beverages
  • Supportive and highly collaborative work environment
  • Health check-up support
  • top-tier equipment/hardware support
  • A front-row seat to the generative AI infrastructure revolution
  • Competitive compensation
  • startup equity
  • health insurance
