Answer 1

Add the object to the JobDataMap:

JobDetail job = JobBuilder.newJob(MyJobClass.class)
                          .withIdentity("MyIdentity",
                                        "MyGroup")
                          .build();
job.getJobDataMap()
   .put("MyObject",
        myObject);

Access the data from the JobDataMap:

var myObject = (MyObjectClass) context.getJobDetail()
                                      .getJobDataMap()
                                      .get("carrier");
