[DevaRextusidis]

i would advice not taking the job for one simple reason: you will be asked to edit articles etc (i am assuming you are joining as sub-editor) which refer to Qadianis as ahmadis. now ahl ul sunnah do not really bother with names. shias can call them whatever they wish, bahai can call them whatever they wish. with this particular name is a connotation however.
ahmadi means 'from ahmad'.
which ahmad?
for us it is Prophet Muhammad (PBUH) the Seal of the Prophets.
for the qadiani kafir it is mirza ghulam ahmad qadiani!

they say when the Qur'an mentions ahmad it doesnt mean our Prophet (PBUH) naufdhubillah but that kafir mirza ghulam ahmad. his name wasnt ahmad his name was ghulam ahmad. so to call them ahmadi is a crime to say the least. it is attestation of their belief even unconsciously.
had they called themselves mirzai (from mirza), ghulam ahmadi (from ghulam ahmad) or qadiani (from qadian) that would have been fine. but his name isnt ahmad. so why ahmadi? it is because of that surah.
this is the opinion of ml. yusuf ludhianvi shaheed (in sha Allah). i do not remember whether he considers it kufr to call a mirzai 'ahmadi' but he mentioned it in strong words.
best avoid it.
express tribune with their belief of religious equality expect thier employs to uphold the same tradition at least at work. imagine if you edit a piece and the mirzais are mentioned as ahmadi and you cant edit it because of your job. would it be worth it?

just some advice. you can read further into the matter.
