I guess the issue is using the mapped entity itself. Try using a DTO (create new dto class)

public class JobDetailsDTO
{
     public int JobID { get; set; }
    // Other fields you may need
}

And then:

using(var db = new jQueryAjaxEntities())
{
    var job = db.jobdetails.Select(x => new JobDetailsDTO
        {
            JobID = x.JobID,
            Task_Name = x.Task_Name,
            Description = x.Description,
            Date_Started = x.Date_Started,
            Date_Finished = x.Date_Finished,
            Status = x.Status,
        }).ToList();

        return Json(job, JsonRequestBehavior.AllowGet);
}
