Job Title Suggestions?

I have a quick question regarding a job title I need to create for a position I've just been promoted into. I work at the in-house post facility for an ad agency and am replacing the old broadcast engineer. I will be IT supporting 3 Avid suites, 3 Final Cuts, 2 After Effects artists, an XSERVE that ties them all together, Avid Unity, FTP Servers, and a few other odds and ends. I will also be doing some creative work in and among all those facets of the department as needed. The last main task will be interfacing with all the editors in the various rooms to make sure all their workflows are up to snuff and smooth.

Essentially I am the #2 in the department to my manager, but I cannot have any managerial aspect in the actual title or I lose my overtime. Any thoughts on this would be really helpful. TIA!
