DevOps Engineer

Azure Kubernetes Service (AKS)

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.
• Coordinating with engineering teams to maintain

  production stability

  .
• Enhancing batch orchestration workflows in

  Airflow

  .
