• Build automation for provisioning, configuration, upgrades, scaling, recovery, and other managed service workflows.
• Write maintainable Go code and develop unit, integration, and cluster-based tests.
• Support CI/CD pipelines for building, testing, packaging, and releasing Kubernetes platform software.
• Integrate with Kubernetes networking, storage, ingress, certificates, scheduling, security, and cluster lifecycle capabilities.
• Contribute to automation using Helm, Terraform, GitOps, Argo CD, Flux, and related tooling.
• Implement secure defaults, least-privilege RBAC, secrets handling, workload isolation, and operational guardrails.
• Build observable and supportable software using logs, metrics, events, health checks, and status conditions.
• Troubleshoot Kubernetes workloads, controller behaviour, failed reconciliations, deployments, and automation issues.
• Collaborate with engineering, SRE, security, and application teams, and contribute to documentation, runbooks, and knowledge sharing.

Experience & Qualifications

• 3+ years of experience in software engineering, platform engineering, DevOps, infrastructure automation, cloud engineering, or SRE.
• Experience developing in Go, or strong software engineering experience with the ability to work in Go.
• Practical experience with Kubernetes, containers, Linux, and cloud-native deployment patterns.
• Familiarity with Kubernetes APIs, CRDs, controllers, reconciliation loops, RBAC, events, status conditions, and resource lifecycle.
• Experience with Git, CI/CD, automated testing, and code review.
• Working knowledge of Helm, Terraform, GitOps, Argo CD, Flux, or similar tooling.
• Understanding of Kubernetes security concepts including RBAC, secrets, namespaces, network policies, admission controls, and workload isolation.
• Strong troubleshooting, communication, and collaboration skills.

Nice to Have

• Experience with Kubebuilder, Operator SDK, controller-runtime, client-go, or similar frameworks.
• Experience developing Kubernetes Operators, controllers, admission webhooks, or platform automation.
• Experience with EKS, AKS, GKE, Rancher, Spectro Cloud, or similar platforms.
• Familiarity with Prometheus, Grafana, Loki, Fluent Bit, ELK/EFK, Istio, Linkerd, Cilium, Velero, Kasten, or Stash.
