Mongo find by id from one collection in other on remove

var id = db.getCollection('first_collection').find({jobClass:"com.example.CleanerJob"}, { _id: 1 }).next()._id;
db.getCollection('second_collection').findOne({"jobId":id});
db.getCollection('first_collection').findOne(id);

Test it on your local. If it is ok, replace all "findOne" with "remove"
