Sorting parent objects with multiple children

I'm working with an application for the construction industry which lets users manage and organize their daily jobs. Part of this app is a view in which you can add jobs and assign cost codes (the specific type of work) to each job. The cost codes are already drag-able, however there also needs to be a way to organize the jobs. In terms of technical limitations, jobs can't be draggable but they can be sortable.

So my question here is how do I clearly show that these top-level objects are sortable? Where should I expose that functionality? On each of the parent "Job" elements, or at the top?

Take a look at "Bridge Sample Estimate" and "Country Road 14" - these are the jobs that need to be sortable:
