senior or architecture is better I think

look at the post I put above with a successful case .
I think it is better talk to experienced lawyer to see if they have successful case (job title change similar as yours) before.
The important thing is have DOL officer to believe your case doesn't against law.

学士学位加5年经验可以申请EB2 PERM

这里的法律重点是在申请中证明申请人的5年相关经验Showing Increasing Level of Responsibility，具体表现在申请人的工作职位在过去的5年中从Junior Level晋升至Senior Level或者申请人的Job Deion从比较简单变得比较复杂，或者申请人Supervise的人数不断增加等等。在申请中还需要附加一份学位鉴定，说明学士学位加5年相关经验等同与该行业的硕士学位。

Good luck
