In Laravel 5.4 I have the following relation that works fine in Set model which belongsToMany of Job model:

public function jobs()
    {
        return $this->belongsToMany(Job::class, 'eqtype_jobs')
               ->withPivot(['created_at','updated_at','id'])
               ->orderBy('pivot_created_at','desc');
    }

The above relation returns all jobs that the specified set has been joined ordered by the pivot table's (eqtype_jobs) field created_at DESC.

The SQL printout of $set->jobs()->paginate(20) Looks like the following:

select `jobs`.*, `eqtype_jobs`.`set_id` as `pivot_set_id`,
`eqtype_jobs`.`job_id` as `pivot_job_id`,
 `eqtype_jobs`.`created_at` as `pivot_created_at`,
`eqtype_jobs`.`updated_at` as `pivot_updated_at`,
 `eqtype_jobs`.`id` as `pivot_id` from
`jobs` inner join `eqtype_jobs` on `jobs`.`id` = `eqtype_jobs`.`job_id` where
`eqtype_jobs`.`set_id` = 56
 order by `pivot_created_at` desc limit 20 offset 0
