Hi @holychs ,

It is possible to do using lookup in Databricks Asset Bundles.
You define the job id variable that finds id of the job based on its name and use this variable to specify job_id in the run_job_task. Here is the code:

variables:
  my_job_id:
    description: id of the job
    lookup:
      job: "my_job"

resources:
  jobs:
    my_job:
      name: my_job
      tasks:
        - task_key: my_task
          notebook_task:
            notebook_path: <notebook path>
          existing_cluster_id: "<cluster id>"
    
    parent_job:
      name: parent_job
      tasks:
        - task_key: run_child_job
          run_job_task:
            job_id: ${var.my_job_id}
            job_parameters:
              my_param_value: my_param_value
  
targets:
  dev:
    mode: development
    default: true
    workspace:
      host: <workspace url>

The above code correctly deployed a job:
