Arquiteto de Plataforma Kubernetes/OpenShift e GitOps

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Kubernetes/OpenShift and GitOps Platform Architect based in Brazil.

In this role, you will lead the design, implementation, operation, and continuous improvement of enterprise-grade Kubernetes and OpenShift platforms in on-premises environments. You will shape the platform architecture around GitOps principles, with a strong focus on ArgoCD, automation, reliability, and security. Working hands-on as a technical authority, you will guide architectural decisions while ensuring infrastructure is scalable, consistent, and maintainable. You will also drive governance, observability, and DevSecOps practices across clusters and applications. The role combines strategic architecture with practical engineering, including complex troubleshooting and platform lifecycle management. This is a fully remote, full-time opportunity in Brazil and is also open to professionals with disabilities.

Accountabilities

• Design, deploy, operate, and maintain on-premises OpenShift and Kubernetes platforms using a GitOps approach.
• Define and maintain ArgoCD architecture, including high availability, cluster and environment organization, and repository strategies.
• Configure and manage ArgoCD ApplicationSets, projects, role-based access control (RBAC), single sign-on (SSO), and synchronization policies, including self-heal, prune, and sync waves.
• Develop and maintain Helm charts, Kustomize overlays, and environment-specific configuration standards to minimize duplication and configuration drift.
• Operate and automate the underlying platform infrastructure, including networking, load balancing, storage, upgrades, backups, and recovery processes.
• Investigate and resolve complex platform incidents, such as OutOfSync or Degraded applications, stalled synchronization, resource conflicts, and unauthorized manual changes.
• Establish Git-based change governance through pull requests, approval workflows, branch protection, and audit trails.
• Implement security and compliance controls using tools and practices such as OPA/Gatekeeper, Kyverno, manifest validation, image scanning, SAST, and artifact signing.
• Monitor the health and performance of ArgoCD, clusters, and applications, configuring metrics, dashboards, alerts, and notifications.
• Automate infrastructure and operational activities, measuring and tracking improvements in efficiency and reliability.
• Participate in technical architecture decisions, clearly communicating design choices, trade-offs, risks, limitations, and alternative solutions.

Requirements

• Completed bachelor's degree in Information Technology or a related field.
• Hands-on experience operating OpenShift and/or Kubernetes platforms in on-premises environments.
• Previous experience as a technical reference, platform architect, or solution architect, with direct responsibility for platform engineering rather than indirect use or pipeline-only involvement.
• Practical experience across the full platform lifecycle, including architecture decisions, implementation, operations, maintenance, and complex troubleshooting.
• Ability to explain architectural decisions, trade-offs, standards, security approaches, automation strategies, and operational practices using concrete examples.
• Strong knowledge of GitOps technologies and practices, particularly ArgoCD, ApplicationSets, Helm, and Kustomize.
• Experience managing deployment lifecycles and infrastructure governance through GitOps.
• Ability to standardize, operate, troubleshoot, and automate platform infrastructure in addition to delivery pipelines.
• Knowledge of DevSecOps, observability, enterprise integrations, and security practices.
• Experience with bare-metal infrastructure, VMware, OpenShift, and/or Rancher environments.
• Knowledge of backup and disaster recovery strategies, as well as cluster and platform component upgrades and rollbacks.
• Infrastructure automation experience using tools such as Ansible, Terraform, or Cluster API.
• Strong analytical, problem-solving, and communication skills, with the ability to take technical ownership and collaborate across teams.

Benefits

• Fully remote work model in Brazil.
• Full-time employment.
• Meal or food allowance.
• Discounts on courses, universities, and language-learning institutions.
• Access to a learning platform offering free, updated online courses and certificates.
• Mentoring opportunities.
• Discount program for medical consultations and examinations.
• Medical insurance.
• Dental insurance.
• Discounts and special offers at a range of partner establishments.
• Travel benefits and discounts.
• Pet care partnership.
• Open to candidates with disabilities.
