الجواب وبالله التوفيق
As per the situation described in your question when you are already working, switching it to a different job without a Shar‘ai excuse is not advisable especially when you do not have the required experience for this new job, the new job involves lying, wearing non-Shar‘ai clothing and you are not confident in making this move either.
Therefore our recommendation is to continue your current job and explain softly and gently to your parents that Allah Subhanahu Wa Ta‘ala will put barakah in your current job in-shah-Allah.
You should also read “Ya-Mughni” daily, 125 times after salatul-Isha.
واللہ اعلم بالصواب
