Using a Group or Role to Variable to customize a build script

[Don Meuth]

I am new to Jenkins, and we are migrating multiple scripts to Jenkins from other environments. 

We basically have 2 Roles with more to come  Developers and Administrators 

We would like to be able to write a build script once and tailor the input fields based upon the user's defined role. 

Is there a way to get, in a build script the Role or Group that a user belongs to? 

For example we allow our developers to build and deploy to a Project environment, but only Admins can deploy to QA and Production.  if we can limit the choices (via a script) for developers to only show the Project environment for input, we can now write a script once and use it for many different environments. 

I have set up Groovy scripts to pull the information from files, and if I can supply the group or role information the script can pull based upon that information.
