Saturn in Twelfth House (from
https://www.indastro.com/house/saturn-12th-house.html)
Saturn in this house gives an uncanny love for seclusion. You are likely to be mentally mature and have a philosophical bent of mind. Unless you love staying alone for long, this can be quite an unfavorable placement of Saturn for the native. Saturn in 12th house gives a lot of troubles, brought upon by circumstances or people. Sometimes, their health may go downhill due to some chronic disease. They may have to face frequent hospitalization.
At others, they may be victim to imprisonment or losses due to others. Such a person is likely to be involved in human welfare and service somehow. But they will be in an occupation where they work from the back end. On the other hand, there could also be a strong desire to escape societal pressures and live on your own. The person has the capability to acquire higher knowledge of spiritual and social realms.
-------------
in general, lagna lord (shani) to be in 12H (house of expense) is not favorable. it may demand lot of hard-work ( for which shani is karaka) but all work will go either waste or as sacrifice for the benefit of others.
-------------
for ambassador kind of jobs:
sun + venus connection is required. i don't see this for you, so, i cannot say anything.
i don't see chances for jobs like high rank govt officers too.
---------------
moon is alone in 7,8,9H (ignoring ketu): This forms kemadruma, but, with planets being available in kendra & trikona,
you will never care about death, enemies, accidents, lonliness, sufferrings, bad-lucks, failures, losses, obstacles,diseases in life.
(please confirm whether i am right).
