    It is unclear to me, what you are asking for.
    You can get entity from the same job, you get aspect.

    Well, there's a few ways to get an entity from an aspect. 1. is doing it while iterating, so if you're using SystemAPI.Query you can use .WithEntityAccess and if you're using IJobEntity you simply need one parameter to be an entity.

    That said there's also option 2, if a core part of your aspect needs entity access, then it might make more sense to have your aspect get the entity, which you can do by having a field in your aspect be of type Entity. Just like RefRO and similiar in an aspect, it will know to assign the property when getting the aspect.

    Code (CSharp):
    1. readonly partial MyAspect : IAspect {
    2.     readonly Entity myEntity;
    3.     // etc ...
    4. }
