Your primary focus will be designing, implementing, and managing Infrastructure-as-Code to deliver self-service, declarative cloud resource provisioning through Kubernetes-native APIs. Leveraging senior-level Kubernetes expertise, you will define reusable infrastructure patterns, author declarative resource definitions, and build composable templates that enable development teams to provision and manage cloud resources consistently, securely, and at scale. You will collaborate closely with Architects and engineering teams to evolve the platform from manual and imperative workflows toward a fully GitOps-driven, policy-governed infrastructure model - ensuring reliability, repeatability, and compliance across all environments.\nResponsibilities:\nLeverage Engineering background and skills as an Infrastructure-as-Code Platform EngineerDesign, develop, and maintain declarative infrastructure patterns using Crossplane and Helm to enable self-service cloud resource provisioning.\nBuild, test, and version reusable IaC components (Compositions, Helm charts, Configuration Packages) within a common infrastructure framework.\nUnderstands Semantic versioning and release management as applied to infrastructure artifacts and chart repositories.\n\nComplete understanding of Software Development Lifecycle as it applies to infrastructure codeExperience with breaking down infrastructure components into modular, composable, and version-controlled resources.\nExtensive understanding of Git branching methodologies and their impact on infrastructure code promotion across environments.\n\nInfrastructure-as-Code with Crossplane & HelmDesign and maintain Crossplane Compositions, CompositeResourceDefinitions (XRDs), and Claims to provision and manage cloud resources as Kubernetes-native APIs.\nBuild and publish reusable Crossplane Configuration Packages for self-service infrastructure consumption by development teams.\nConfigure and manage Crossplane Providers, handling credentials securely through Kubernetes Secrets or external secret stores.\nDevelop, version, and maintain production-grade Helm charts for internal services, platform components, and third-party tooling.\nManage Helm chart repositories (OCI registries) and implement chart testing pipelines using helm lint, helm unittest, and kubeconform.\nBuild Helm templating patterns that support multi-environment, multi-cluster deployments with values overlays and library charts.\nImplement GitOps workflows (ArgoCD or Flux) for continuous deployment of both Helm releases and Crossplane claims.\nMigrate legacy IaC (e.g., Terraform/HCL) toward Crossplane-managed Kubernetes-native resource models where appropriate.\n\nCI/CD & DevOps Platform FluencyMaintain a strong working understanding of CI/CD platforms and DevOps toolchains to ensure IaC components integrate seamlessly into existing build, test, and deployment pipelines.\nCollaborate with DevOps teams to embed infrastructure validation, policy checks, and drift detection into pipeline stages.\nTroubleshoot issues end-to-end across the infrastructure delivery chain (source, build, package, deploy, and runtime) in coordination with DevOps engineering.\n\nSupport and evolve the IaC platform by:Supporting the full infrastructure lifecycle ensuring highly scalable and reliable service.\nUnit and integration testing of new and proposed infrastructure changes.\nIdentifying deficiencies and applying solutions to infrastructure patterns through IaC principles and framework.\nUtilizing monitoring and observability to both troubleshoot infrastructure drift and provide feedback into the infrastructure development lifecycle.\nUnderstanding and promoting infrastructure and application Security best practices.\nParticipating in on-call to support the IaC platform and underlying infrastructure.\nAuthoring support documentation, runbooks, and user guides for internal teams consuming IaC resources.\n\nWork closely with Architects and Leads to understand infrastructure requirements and align with product and technology vision.\nContinuously explore and stay current on new and emerging IaC technologies, Kubernetes ecosystem tooling, and cloud provider capabilities.\nRequired Knowledge and Experience:\nMinimum 10 years of experience as a DevOps or Systems Engineer or a bachelor's degree and 6 years of experience.\nKubernetes (Senior-Level Expertise) -Deep understanding of cluster architecture: control plane, etcd, kubelet, kube-proxy, and API server internals\nHelm and Kustomize\nCRDs, services, operators\nAdvanced RBAC design, NetworkPolicies, PodSecurityAdmission, and admission controllers\nMulti-cluster management strategies and federation patterns\nResource scheduling, quotas, LimitRanges, priority classes, and pod disruption budgets\nTroubleshooting node-level, networking (CNI, DNS, Ingress), and storage (CSI, PV/PVC) issues\nCluster lifecycle management: upgrades, node pool rotation, and disaster recovery\nPerformance tuning: HPA, VPA, KEDA, and resource right-sizing\nFamiliarity with Rancher management server is a plus.\n\nInfrastructure-as-Code (Crossplane & Helm) -Crossplane - Compositions, XRDs, Claims, Providers, and Composition Functions\nUpbound as a managed Crossplane platform - Upbound Spaces, managed control planes, and the Upbound Marketplace for Providers and Configurations\n Helm 3 - chart development from scratch, subcharts, library charts, values schema validation\nExperience managing Helm chart repositories (OCI registries)\nUnderstanding of Crossplane's continuous reconciliation model and drift detection\nExperience with GitOps tooling (ArgoCD or Flux) for deploying Helm releases and Crossplane resources\nFamiliarity with Open Policy Agent (OPA), Gatekeeper, or Kyverno for IaC policy enforcement is a plus\n\nArgoCD (Practitioner Usage) -Creating and managing Application resources and ApplicationSet resources\nUnderstanding of App of Apps pattern for organizing infrastructure deployments\nConfiguring sync policies and sync waves for orchestrated rollouts\nUsing Helm charts and Kustomize overlays as application sources\nIntegrating ArgoCD applications with Git repositories for GitOps-driven delivery\nMonitoring application sync status, health checks, and troubleshooting failed syncs\nUnderstanding sync errors, drift detection, and manual vs. automated sync behavior\n\nDocker containers -dockerfile\ndocker build, kaniko\ndocker registry\n\nSource code management -Bitbucket (git)\nGithub\nGit branching\nCode reviews and pull request approvals.\n\nScripting Languages -bash\npython\nYAML\nFamiliarity with PowerShell is a plus.\n\nProgramming Languages -Go language\nGroovy\nYAML\nAnsible\nHCL -
