Senior Platform Engineer - Core Infrastructure

What You’ll Do

• Architect, deploy, and operate Kubernetes clusters across Lambda's bare-metal datacenters.

• Build and maintain automation for cluster lifecycle management: provisioning, upgrades, and scaling.

  • Similar to SRE-level coding abilities (small scripts, k8s operators/CRDs a plus)

• Own the reliability, performance, and security of Kubernetes workloads in production.

• Implement observability, logging, and alerting for clusters and critical workloads.

• Partner with product teams to design scalable, cloud-native services.

• Set the standards for resource management, networking, and RBAC across the platform.

• Lead incident response, root-cause analysis, and post-mortems for platform issues.

• Mentor junior engineers and raise the bar for platform engineering across the org.

You

• 5+ years in Platform, Infrastructure, or SRE roles, including running Kubernetes in production at scale.

• Deep knowledge of Kubernetes internals and day-2 operations (upgrades, scaling, troubleshooting).

• Strong with Helm, Kustomize, or similar, and GitOps-based delivery.

• Proficient with Linux systems and understanding of system-level operations.

• Proficient with infrastructure-as-code (Terraform, Pulumi, or equivalent).

• Solid grounding in networking, service meshes, and container runtimes.

• Hands-on with observability stacks (Prometheus, Grafana, OpenTelemetry).

• Strong coding skills in Go or Python for automation and tooling.

• Practical security experience: network policies, secrets management, and image scanning.

Nice to Have

• Experience with multi-cluster, multi-cloud, or hybrid environments.

• Knowledge of GPU scheduling, HPC workloads, or ML/AI infrastructure.

• Experience with workflow orchestration / durable execution frameworks (Temporal, Cadence, or Argo Workflows).

• Exposure to cost optimization and capacity planning for large clusters.

• Contributions to CNCF or Kubernetes open-source projects.

• CKA/CKS certification.
