Praise be to Allaah.
There is no doubt that
paying a bribe in order to get a job is haraam both for the one who pays the
bribe and the one who accepts it, and for the one who mediates between them.
No exception is made except in cases where the bribe is paid to remove
injustice or to attain rights which can only be attained through bribery. In
that case it is permissible for the one who gives it but it is haraam for
the one who takes it.
See the answer to question
no. 25758.
So long as the job is based
on a test for applicants, bribery is haraam in this case, because you were
no better than anyone else and you have no particular right which you had to
pay a bribe to attain.
There is a warning
concerning bribery which should scare any wise person away from engaging in
it. It was narrated that Abu Hurayrah (may Allaah be pleased with him) said:
The Messenger of Allaah (peace and blessings of Allaah be upon him)
cursed the one who offers a bribe and the one who takes it.

al-Albaani in Saheeh Abi Dawood.
If you have repented to
Allaah and you give some money in charity, as you say, then there is nothing
wrong with you remaining in this post, so long as you are qualified to work
in it, because appointing someone who is not qualified is a betrayal of
trust, the harmful effects of which are obvious to all.
