OP,
In the nicest possible way, if you want to move you need to ‘man up’ a bit. It’s an awful phrase, but the right one here.
It’s unusual for anyone to meet 100% of the job spec requirements. If you get over half, consider applying. Most blokes would.
On the part time bit - get in touch and ask if they’d consider part time. Most jobs are advertised as full time as part time is a much narrower pool to recruit from.
(and you already have responsibility for preventing people dying, so that’s not new).
Get on LinkedIn, update your profile and mark it as looking for jobs. Some recruiters might find you and help with ideas.
As a reality check, you’re unlikely to find something that:
can match your current pay from day 1.
is very close to home
is less stress
is less responsibility
same part time arrangement
In reality, some of those probably matter more to you than others. It’s worth having a think about which.
(also, ask any reps you have contacts with).
