Job Specifications

Lambda, The Superintelligence Cloud, builds Gigawatt-scale AI Factories for Training and Inference. Lambda’s mission is to make compute as ubiquitous as electricity and give every person access to artificial intelligence. One person, one GPU.

If you'd like to build the world's best deep learning cloud, join us.

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.

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.

What You’ll Do

Operate and maintain bare-metal Kubernetes clusters, scaling up to thousands of nodes
Handle cluster degradation, recovery, resizing, and incident response using fleet management tools
Participate in a well-managed on-call rotation for critical incidents
Assist customers with Kubernetes questions, workload integration, storage, and authentication
Work closely with our HPC Ops and Datacenter Ops teams for low-level or cross-functional issues
Use Python and Golang to create tooling and automate the validation of platform quality.
Design, build, and maintain scalable control plane services, operators, and custom controllers for Kubernetes
Develop automation for cluster lifecycle management: provisioning, upgrades, patching, and deletion.
Define and implement SLOs and SLIs for Kubernetes services, workloads, and platform reliability.

About You

Can work with customers during incidents either via tickets, live messaging, or as part of a larger call.
Familiarity with observability tools like Prometheus, Grafana, FluentBit, and CI/CD pipelines
Proven experience provisioning Kubernetes using tools such as kubeadm, Cluster API, or similar

Nice-to-Have

Deep Kubernetes expertise: CRDs, CSI, CNI, Kubernetes Operator Coding experience
Exposure to HPC clusters, AI/ML workloads, or large-scale GPU clusters
Hybrid or multi-cloud Kubernetes environment experience
Contributions to CNCF projects or Kubernetes SIGs

Why Join Us
