There is a dual ladder setup. Where you can have Administrator, Systems Engineer, Sr. Systems Engineer, Lead, Architect, Sr Architect, etc. These will have parallel tracks to equiv. management positions for benefits and perks (bonus levels, etc).

Now obviously you can't have every employee promoted to a Sr. Architect or Fellow, but that is ok be cause not everyone can (or want to) obtain that necessary skill set. A while back I recall seeing a grid with various levels, what management title that would typically mirror, and the skills that would be required for each level.
