+### Delegation of managing a Job object to external controller
+
+{{< feature-state for_k8s_version="v1.30" state="alpha" >}}
+
+This feature allows delegating reconciliation of a Job object to an external
+controller. Jobs with a custom value of the `spec.managedBy` field - any value
+other than `kubernetes.io/job-controller` - are skipped by the job controller,
+and their reconciliation is delegated to an external controller, indicated by
+the value of the field. Jobs that don't have this field at all, or where the
+field value is the reserved string `kubernetes.io/job-controller`, are reconciled
+by the built-in job controller. The value of the field is immutable.
+
+{{< note >}}
+The external controller should not create pods with the finalizer name
+`batch.kubernetes.io/job-tracking` reserved for the built-in controller.
+{{< /note >}}
