• Define and enforce network policies, security controls, and resource constraints.
• Deploy and manage platform components: Ingress Controller, Gateway API, External DNS, Cert Manager.
• Implement observability tooling (Prometheus, Grafana, ELK) and codify dynamic alerting.

Golang Development

• Build Golang operators to automate cloud infra and Kubernetes resource management.
• Develop REST APIs for GitOps workflows, product configuration, and automation bots.
• Write clean, modular, and testable code with strong engineering practices.

GitOps & CI/CD

• Define and manage Argo CD applications using Kustomize (Helm-to-Kustomize migration experience preferred).
• Codify GitOps standards and automate application onboarding.

Cloud Native Tooling

• Work with technologies like Istio, Crossplane, Vault, OPA/Kyverno, Operator SDK.

Golang & Software Engineering:

• Proficiency in software engineering (any language) with a strong willingness to learn Golang.
• Experience with unit and integration testing, clean code principles, and modular design.
• Ability to build and maintain REST APIs.
• Experience building Golang operators for automating cloud infrastructure and Kubernetes platforms (e.g., tagging resources, automating resource creation, IAM/IRSA automation, secrets management).
• Experience developing Golang APIs for GitOps workflows, product configuration, and automation (e.g., merge bots, PR automation).

GitOps & CI/CD:

• Hands-on experience with Argo CD, including defining and managing Argo CD applications.
• Proficiency with Kustomize for GitOps manifests; ability to convert Helm charts to Kustomize.
