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 Must-Have
6+ years of experience in a SRE, operations engineer, or similar role, with a deep knowledge of running Linux clusters and systems.
Strong programming skills in Go and Python; experience with GitOps (e.g., ArgoCD), Helm, and Kubernetes operators.
Proven experience operating Kubernetes clusters in production environments (on‑prem, EKS, GKE, or similar).
Can work either independently with limited direction or as part of a team.
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.
