Help to understand the ending verb "動かねーんじゃね"


Original sentence: アドビやら、お絵描き系のアプリは、誰かが実証しない限り、 **動かねーんじゃね** ？ I can't
understand the structure of the last verb. So far I understood that
動か(conjugated form) + ねー(negative particle) + んじゃ(???) + ね(question particle).
What does んじゃ mean




動か is the conjugated form of the verb 動く  
ねー is the colloquial version of the negative auxiliary verb ない  
ん is the colloquial version of the nominalization particle の  
じゃ is the colloquial version of the auxiliary verb で (the dictionary form is
だ)+ the particle は  
ね (or ねえ, ねぇ or ねー) is also the colloquial version of ない (but the ね/ない here is
an adjective not an auxiliary verb)  
  
So... more politely it'd be like 動かないのではないですか？or 動かないのではありませんか？And... if you
put it more feminine, I'd say... 動かないんじゃない？(I think it's like "I wonder if it
wouldn't work" "I doubt it would work" or "It wouldn't work, would it?" ...
sorry for my poor English) ^^
