How should I deal with 产生 in this sentence?
求职者一定要先确认自己签订的劳动合同是否具备产生法律约束力的条件。Let us first simplify the latter half of the sentence.

求职者一定要先确认自己签订的劳动合同是否具备条件。What kind of 条件 does it 具备？产生法律约束力的条件 - the condition that leads to legally binding

If you literally translate "产生", it means produce. Which would make sense to extend its meaning to lead to. So if I am translating your sentence, I will do it this way:

Job seekers should definitely first check for themselves, whether or not the employment contract he is about to sign leads to the condition of legally binding.
