Just for completeness, in case someone has the same problem.
Adding the indexes reduced the CPU usage from 100% during the night (1 Core
used by MySQL) to ~50% peak and maybe 25% average.
create index ix_job_jobtdate on Job(JobTDate);
create index ix_jobmedia_mediaid on JobMedia(MediaId);
Without the indexes (4 Core system):
