Senior Software Engineer - Managed Kubernetes

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.Note: This position requires presence in our San Francisco, San Jose, or Bellevue office location 4 days per week; Lambda’s designated work from home day is currently Tuesday.About The RoleWe are seeking a Senior Software Engineer to join our Managed Kubernetes (Mk8s) team. You will play a crucial role in shaping the architecture, reliability, and automation of our Kubernetes-based infrastructure, which powers mission-critical workloads across our global platform.Lambda is building the AI Cloud of the future. We are seeking a Senior Software Engineer to help our development of our Managed Kubernetes platform. Think GKE, but purpose-built for AI workloads and running on bare metal. In this role, you will help build the infrastructure that powers the next generation of AI training and inference at scale.As a Senior Engineer on our Orchestration team, you will contribute to Lambda's managed orchestration services, including Managed Kubernetes, Managed Slurm on Kubernetes, and higher-level platform services for inference and AIOps. You'll work at the intersection of distributed systems, GPU-accelerated computing, and Cloud Native infrastructure to build systems that are reliable, performant, and elegantly simple for our customers.This is not a role for someone who just operates Kubernetes; it's a role for an engineer who understands how compute, network, storage, and security interact, and can build solutions that account for that context — even while focused primarily on the orchestration layer. You'll be working closely with NVIDIA's open-source ecosystem, and partnering with internal teams across the stack to deliver a world-class managed platform.What You’ll DoDesign, build, and maintain scalable control plane services, operators, and custom Kubernetes controllers; develop automation in Go/Python for end-to-end cluster lifecycle management — provisioning, upgrades, patching, and deletionBuild GPU-aware orchestration systems, working within the platform architecture to support GPU scheduling and resource allocationPartner with the Network team on networking solutions for AI workloads: CNI integration (Cilium, Multus), high-performance fabrics (InfiniBand, RoCE), RDMA, and GPUDirectWrite resilient systems that handle failure gracefully — timeouts, retries, backoff, and degraded-mode operation — across large-scale distributed environmentsDevelop platform services for inference: model serving infrastructure, autoscaling based on inference load, and multi-model deployment patternsBuild internal tools and CLIs that let ML/AI teams deploy and monitor their own inference servicesSupport and debug production issues through on-call rotationRequired QualificationsHave 6+ years of experience in software engineering, with a track record of owning significant technical scope within a team (e.g., driving a project from design through production, or acting as a de facto tech lead on a workstream)Deep understanding of Kubernetes internals: controllers, schedulers, operators, CRDs, CSI, CNI, and the extension patterns that make Kubernetes powerfulSolid grasp of distributed systems fundamentals — fault tolerance, graceful degradation, and failure handling in large-scale environmentsExperience operating the control plane and low-level pieces of large-scale Kubernetes clustersExperience with observability at scale: Prometheus, Grafana, distributed tracing, and building actionable alerting systemsStrong programming skills in Go and Python; ability to collaborate effectively on shared codebasesSolid knowledge of Linux systems, networking, containers, and cloud infrastructureTake pride in owning and delivering core components of products and platformsPreferred QualificationsExperience building and operating managed Kubernetes services (GKE, EKS, AKS, or similar) or working on Kubernetes control plane componentsHands-on experience with NVIDIA's GPU/networking ecosystem: GPU Operator, device plugins, DCGM, MIG, Network Operator, NCCL tuning, or similarFamiliarity with HPC and traditional job schedulers (Slurm) and Kubernetes-native batch scheduling (KAI, Volcano, Kueue)Familiarity with GPU, InfiniBand, RDMA, or high-performance computing on KubernetesExposure to storage architecture for AI/ML workloadsPast contributions to CNCF projects or Kubernetes SIGs a plusIf you don’t meet all of these requirements but believe you may be a good fit, please still apply and provide a cover letter that helps us understand your experience and readiness for this role.Why LambdaLambda is building the essential infrastructure for the AI era. We're not just another cloud provider: we're a company founded by ML practitioners, for ML practitioners. Our customers include leading AI research labs and enterprises pushing the boundaries of what's possible with artificial intelligence.What Makes This Role SpecialYou'll be building core platform services the world's largest AI companies will consumeNVIDIA partnership: Deep integration with NVIDIA's GPU and networking stack, working with cutting-edge open-source toolingReal technical challenges: Massive scale GPU clusters and the unique demands of AI workloadsCross-stack exposure: Work at the intersection of Kubernetes, networking, storage, and compute — gaining depth across the full infrastructure stack that powers AI workloads, not just the orchestration layerDirect impact: Your work enables AI breakthroughs.
