Senior Kubernetes Engineer

Job Summary We're hiring a Kubernetes Engineer to design, secure, and operate enterprise-grade, multi-cloud Kubernetes across major providers. You'll enable a compliant, multi-tenant platform with "secure-by-default" controls, integrate cluster operations into Git-based delivery, and support a growing internal developer portal/software catalog and a unified repo for platform assets. The ideal candidate combines deep Kubernetes expertise with strong security, reliability, and audit readiness suitable for healthcare environments. Key Responsibilities Design & Operations • Architect, deploy, upgrade, and scale managed clusters across major clouds with HA control planes and cluster/workload autoscaling. • Operate private clusters restrict control-plane exposure, enforce private API access, use NAT-only egress, and implement approved private connectivity patterns. • Engineer multiple node groups for workload separation and efficiency, heterogeneous instance families, GPU/CPU pools, spot vs on-demand, taints/tolerations, topology spread, and security-focused pools. • Define golden patterns for services/ingress, storage classes, private networking/egress, and cloud load-balancing options. Configuration & Delivery • Maintain declarative manifests and templates, structure environment overlays and reusable modules. • Enable progressive delivery via Git-based workflows with automated policy checks and promotion gates. Security & Compliance • Enforce least-privilege RBAC, namespace isolation, Pod Security standards, and admission policies for image provenance, non-root, and blocked capabilities. • Implement service-to-service encryption with workload identity, certificate issuance/rotation, and policy-based authorization. • Apply deny-by-default network policies, strong secrets hygiene with KMS-backed encryption and rotation, and signed/scan-gated images with SBOM attestations. • Ensure audit-ready logging across control and data planes, route to central logging with detections for risky actions and configuration drift. Observability & Resilience • Integrate metrics, logs, traces, and events, define SLOs/error budgets, scale via reliable signals (including custom/external metrics). • Build self-healing runbooks, conduct chaos/resiliency drills, and implement backup/restore for cluster state and application data. Governance & Cloud Hygiene • Apply org guardrails, allowed-regions, tagging/labeling standards, and automated conformance with remediation. • Document RTO/RPO tiers, test restores and failovers, maintain audit evidence and change traceability. Required Skills & Qualifications • Kubernetes Expertise Operating managed clusters on major clouds, scheduler and node lifecycle, cluster and workload autoscaling. • Private Cluster Operations Private API endpoints, restricted API access, NAT egress, bastion workflows, and private connectivity (peering/VPN/dedicated circuits). • Multiple Node Groups Designing heterogeneous pools, taints/tolerations, topology spread, and right-sizing for cost and performance. • mTLS & Service Identity Implementing workload identity, certificate issuance/rotation, policy-based service authorization, and end-to-end encryption in transit. • Manifests & Packaging YAML proficiency, templating/overlays, Git-based release strategies, and GitOps practices. • Security Depth RBAC design, Pod Security standards, admission policy engines, network policies, secrets management, image signing and vulnerability scan gates. • Networking CNI fundamentals, L4/L7 traffic, ingress/egress, private endpoints, and cross-cloud load-balancing options. • Multi-Tenancy Namespace boundaries, quotas/limits, noisy-neighbor mitigation, and sensitive-workload isolation. • Infrastructure as Code Clusters and cloud resources as code with policy guardrails and drift detection and IaC tools. • Observability & Troubleshooting Metrics/logs/traces, HPA/VPA using trustworthy signals, deep debugging of runtime, DNS/CNI, scheduling, and control-plane issues. • Compliance Mindset (Healthcare) Understanding HIPAA/HITRUST concepts, encryption at rest/in transit, least-privilege, audit evidence, and governed deployment pipelines. • Nice to Have Internal developer portals/service catalogs, progressive delivery, cost-aware right-sizing and capacity forecasting, DR design, and scripting in Bash/Python.
