I interpreted a technician as someone who handles any tech that gets used by the team... from the vehicle's onboard computers, to other misc tech that gets used to enhance their ability to win (IE I have Mac currently working on a helmet which has a visor that doubles as a clear read-out display so the driver can track things like gas, tire wear and tear, a map of the course, etc while never having to take their eyes off the road. Think Google Glass, but better).
That said... I have no idea where to start IC wise, which is why I haven't posted yet. >.<
