At the same time read the prayer of Istikharah on a regular basis, on a specific and appropriate time of the day, every day. This is simply two Rak'ah of prayer just like the morning prayer, and after that you will ask God to give you what is the best for your life here and in the hereafter and to make you satisfied with it. The wording recommended for this supplication after the prayer is as follows:
اَللّهُمَّ إِنِّى أَسْتَخِيرُكَ بِعِلْمِكَ وَأَسْتَقْدِرُكَ بَقُدْرَتِكَ وَأَسْأَلُكَ مِنْ فَضْلِكَ الْعَظيمِ فَإِنَّكَ تَقْدِرُ وَلاَ أَقْدِرُ وَتَعْلَمُ وَلاَ أَعْلَمُ وَأَنْتَ عَلاَّمُ الْغُيُوبِ اَللّهُمَّ إِنْ كُنْتَ تَعْلَمُ أَنَّ هذَا اْلاَمْرَ خَيْرٌ لى فِى دينى وَمَعَاشِى وَعَاقِبَةِ أَمْرِى فَاقْدُرْهُ لى وَيَسِّرْهُ لى ثُمَّ بَارِكْ لى فيهِ وَإِنْ كُنْتَ تَعْلَمُ أَنَّ هذَا اْلأَمْرَ شَرٌّ لى فِى دينى وَمَعَاشِي وَعَاقِبَةِ أَمْرى فَاصْرِفْهُ عَنِّى وَاصْرِفْنى عَنْهُ وَاقْدُرْ لِى الْخَيْرَ حَيْثُ كَانَ ثُمَّ أَرْضِنى بِه
O Allah ! I ask guidance from Your knowledge, and Power from Your Might and I ask for Your great blessings. You are capable and I am not. You know and I do not. And You know the unseen. O Allah! If You know that this affair is good for my deen and my subsistence and for my Hereafter - then ordain it for me and make it easy for me to obtain, and then bless me in it. If You know that this thing is harmful for me in my deen and subsistence and for my share in the Hereafter then keep it away from me, and keep me away from it. And ordain for me whatever is good for me, and make me satisfied with it)." (Bukhari)
Please note this is not about looking for signs after prayer to decide what you want to do. This is about asking God to give you what you think is good for you while putting your trust on God that ultimately He will give you what is the best for you.
As I wrote read this regularly while looking for a job, and keep reading it till you feel that your prayer is answered. However remember, the answer to your prayer could be that sort of the job that you are wishing for, or could be something else that you never thought of. Feeling satisfaction and confidence in the state you are in just now might also be an answer to your prayer.
