I might be mistaken, but it appears to me the OP is talking about Oracle scheduler (DBMS_SCHEDULER), not job manager (DBMS_JOB).
In this case the following views could provide details of the execution:
Sorry if I misunderstood the question.
Its hard to monitor the dba logs tables as there are lots of rows and I dont know the jobs logging it :(
How do I delete all the log tables? Are there other log tables like tha auditing tables that I need to periodically cleanup?
It might cause space problem later.
Is it safe to truncate all the sched log tables?

Please don't be discouraged by the amount of the information. By default the history is kept for 30 days which is not much. If you wish to keep less data you can always use
where N is between 0 and 1000000 days.
exec DBMS_SCHEDULER.SET_SCHEDULER_ATTRIBUTE('log_history', N);
You can also search by job_name which you can find in DBA/ALL_SCHEDULER_JOBS to restrict the amount of info shown. Also there's a timestamp that make it easier to identify the last run.

In Addition ..
1. Use below to identify how many days logs preserved by scheduler views
select max(LOG_DATE),min(LOG_DATE) from dba_scheduler_job_log;
2. Try logging your jobs only when failure occurs
to get job class ..
select job_name,job_class from dba_scheduler_jobs where job_name='<your job name>';
'<job_class>', 'logging_level', DBMS_SCHEDULER.LOGGING_FAILED_RUNS);
Note : You must be granted the MANAGE SCHEDULER privilege to set the logging level of a job class.
3. Purging Logs Manually
