H1B amendment for changing job role?

[Sandhu412]

Hi There, 

I am currently work in the USA full time as QA Automation engineer in the mobile/apps space. In the same team, I have an opportunity to change into a developer role. Obviously, the job description will be different from a QA Automation engineer to a Software Developer. But I have I140 approved (with priority date of Sept 2011). Given the above, I have couple of questions: 

1. Do I need to have my employer file an H1B amendment for the job role change? 

2. Since I am I140 approved in the GC process, would I need to make any further changes to my documentation with respect to Green card process? 

Please clarify and appreciate your help.

1. Yes it is obvious

2. I guess so. I might be wrong...
