A simple solution, I added the below code in default value of Assign field in response form it works now 

var parentDoc = database.getDocumentByID(document1.getParentId())
      return parentDoc.getItemValueString("Developer")

One way to get field values from a parent document (in your case from the Job document) is to use a data context to create a parentDoc object. You can then refer to this parentDoc object to get field values from the parent document.

Start by creating a parentDoc data context:

<xp:this.dataContexts>
    <xp:dataContext var="parentDoc">
        <xp:this.value><![CDATA[#{javascript:
            return database.getDocumentByUNID(currentDocument.getParentId());
        }]]></xp:this.value>
    </xp:dataContext>
</xp:this.dataContexts>

If you just want to display a value from the parent document (and not save it in the response document), you can then use a computed field to display the value from the parent document (using expression language to refer to the field from the parentDoc object):

<xp:text escape="true" id="displayParentField" value="#{parentDoc.field}" />

You can also use the value from the parent document as the default value for an input field:

<xp:inputText id="responseValue" value="#{currentDocument.responseField}" defaultValue="#{parentDoc.field}" />

Short answer, you filter the 2nd data source with the value of the field. It could be the response field on the response doc or the value of the field that exists on both docs.

Long answer, This is a common xPages question, one I have asked myself. Take a look at this question. xPage with multiple datasources has the second datasource always opened in edit mode
