Sure. Contract engineer; this last time as a System Architect. I’ve done it for many of the high tech companies out there (Apple, Microsoft, Dell, HP). Typically in hardware, usually related to audio, acoustics, and signal processing for audio.
Means I get to play with hardware and software, since both affect what you hear and what’s recorded.
FWIW, in the last 5 years I’ve racked up about 800 hours with Microsoft - Typically 1 month a year, on average. Last year (2009) I had zero hours, this year it was 240 hours. So it comes and goes...
Been to Redmond, Cupertino, Houston, Austin, Shanghai, Shenzhen, Dongguan, Singapore, Seoul, Paris, and a few other places for these companies.
Oh, and I’m self-employed. I direct-bill all these companies myself, I don’t go through a contract agency (I set my own company up with each - a requirement if I’m going to work for someone). A gun-for-hire, so to speak, work for the highest bidder.
