Senior Platform Engineer - Core Infrastructure

About the Role

Lambda, The Superintelligence Cloud, is a leader in AI cloud infrastructure serving tens of thousands of customers. Our customers range from AI researchers to enterprises and hyperscalers. Lambda's mission is to make compute as ubiquitous as electricity and give everyone the power of superintelligence. One person, one GPU. If you'd like to build the world's best AI cloud, join us.

Engineering at Lambda is responsible for building and scaling our cloud offering. Our scope includes the Lambda website, cloud APIs and systems as well as internal tooling for system deployment, management and maintenance.

Note: This position requires presence in our San Francisco, San Jose, or Seattle office location 4 days per week; Lambda's designated work from home day is currently Tuesday.

What You'll Do

• Architect, deploy, and operate Kubernetes clusters across AWS and Lambda's bare-metal datacenters.
• Build and maintain automation for cluster lifecycle management — provisioning, upgrades, and scaling.
• 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 and CI/CD pipelines.
• 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 engineers and raise the bar for platform engineering across the org.

Requirements

• 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 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.
