Kubernetes, OpenShift, and GitOps Platform Architect

This is a fully remote position, open to applicants in Brazil.

📋 Description

• Design, implement, operate, and maintain on-premises OpenShift/Kubernetes platforms utilizing a GitOps methodology.

• Define and oversee ArgoCD architecture, ensuring high availability, cluster and environment organization, and repository strategy.

• Implement and manage ApplicationSets, projects, RBAC, SSO, and synchronization policies, including self-heal, pruning, and sync waves.

• Organize and maintain Helm charts, Kustomize overlays, and environment-specific configuration standards to minimize duplication and drift.

• Automate and manage the platform’s foundational components, including networking, load balancing, storage, upgrades, backups, and recovery.

• Investigate and resolve intricate incidents, such as OutOfSync or Degraded applications, stalled synchronizations, resource conflicts, and manual changes (drift).

• Establish Git-based change governance through pull requests, approvals, branch protection, and audit trails.

• Implement security and compliance measures, such as OPA/Gatekeeper or Kyverno policies, manifest validation, image scanning, SAST, and artifact signing.

• Monitor the health of ArgoCD, clusters, and applications; configure metrics, dashboards, alerts, and notifications.

• Automate operational and infrastructure tasks and monitor the resulting enhancements.

• Engage in technical decision-making, rationalize choices, and communicate solution risks, limitations, and alternatives.

⛳️ Requirements

• Bachelor's degree in Information Technology or a related discipline.

• Practical operational experience with OpenShift and/or Kubernetes in an on-premises setting.

• Experience acting as a technical reference or solution architect, with direct involvement in the platform—not simply as an indirect user or pipeline contributor.

• Familiarity with the complete lifecycle: architectural decisions, deployment, support, and resolution of complex challenges.

• Ability to articulate decisions, trade-offs, architectural patterns, security, automation, and operations with tangible examples.

• GitOps expertise: ArgoCD, ApplicationSets, Helm, and Kustomize.

• Management of the deployment lifecycle and GitOps-based infrastructure governance.

• Operation, standardization, troubleshooting, and automation of platform infrastructure, in addition to delivery pipelines.

• Knowledge of DevSecOps, observability, integrations, and security in enterprise environments.

• Experience with bare-metal infrastructure, VMware, OpenShift, or Rancher.

• Understanding of backup, disaster recovery, and upgrades/rollbacks of cluster and platform components.

• Infrastructure automation experience using tools such as Ansible, Terraform, or Cluster API.
