Cloud DevOps Engineer (Kubernetes / Azure) in HUNGARY

Key considerations:

• Ensure proper isolation between batch and live workloads through dedicated Postgres instances and node pools.
• Implement deployment enhancements for simplified node pool dedication between live and batch operations.
• We use Jsonnet configuration code and convert it into Kubernetes YAML manifests.
• Adapt and configure Airflow python DAGs for batch processing orchestration.
• Collaborate closely with the internal team to ensure a smooth transition of sensitive processes.

Team Responsibility

The selected engineers will be responsible for:

• Maintaining and scaling Kubernetes clusters in Azure.
• Ensuring proper (no shared VM) isolation between live traffic and batch operations.
• Supporting deployment improvements for reliability and scalability.
