FLU – I can’t say I’m familiar with the mobile app space, but I agree with the other poster that a good mobie app developer should pick up on device-specific details in a few weeks. A great one, in a couple weeks.
I don’t know if there is such a thing as a class for teaching developers the ropes for the Google device, but that would be a great incentive for any applicants.
I’d suggest finding a great programmer in a space that is as close to your space as possible and wrap Google training, if there is such a thing, into the compensation package.
Or, hire a contractor that is working for Google to teach your new hires what they need to know as a side job. We contractors are whores. We’ll do anything for a side job.
I know a gal who has been programming for many years in many spaces. I have never worked with her, but she seems to be very diverse. Rattled off lots of languages she worked in. Her husband is an independent Mac developer and now has several iPhone apps. I’m sure he could offer his expertise as well. She is looking for work and she doesn’t strike me as greedy. Drop me a personal message with your email and we’ll talk.
