Great question, resumes are a very key aspect of the application process and often get overlooked. For most admissions officers this is one of the first documents they look at in your entire package. So it is very important to put your best foot forward in this department.
To answer your question, I would say for someone with your type of work, the two most important things you should focus on is...
1)Structure
-Create a consistent framework for each entry, i think the structure you have laid out works well for your background
-I would also include a summary header for this job that describes your high-level position and use the subsequent bullets to outline your projects with the format listed below
2)Impact
-Really focus on the impact YOU have made, the structure you have outlined works, so make sure you are identifying your specific role, the context of the project and the results and if possible the results driven by your performance
Hope this helps!
