That would put you one step above me, System Architect.
How about:
Senior Enterprise System Architect
Director of Systems Engineering
Principal System Engineer
Senior Solution Architect
Chief Technologist (if you can swing it with the owners)
My list is not too far off of yours. I got to tell the Director of Systems Engineering how much SAN disk to buy today, that was pretty cool.
Less cool was the 3 meetings, one conference call, and coaching some junior team members who have had really bad support weeks.
