A thankless job
@Andrew. I'll suggest one more IT job in the world of IoT, although I'm not sure anyone really wants it. I'll call it Fix-It person.
With IoT we're talking about plenty of new types of devices that often haven't been networked before. Yes, there's the ever-present example of a refrigerator, along with other household appliances and electronics. There are all those environmental sensors, "intelligent" Starbucks coffee makers, and at-home blood pressure, heart and insulin monitors.
Our networks of the past have been relatively static and easily managed with wires to the desktop, routers in closets and the like. In the IoT we're hooking up devices that are subject to clumsy house-cleaning hands and nasty chemicals. I can envision a dog or cat rubbing against an in-home medical device, or someone trapping an HVAC sensor behind a 50-inch video display. How about sensors in rough environments, such as on railroad switches and highway traffic controls. Wind, water, creatures, and even the occasional random monkey wrench can take those sensors and controls offline pertty quickly.
So Fix-It will have full employment chasing down a never-ending series of "oops". However, I can see them not being popular with the device owners who want instant gratification.
