You won't specialize in one layer; you'll own features end-to-end and make pragmatic decisions at every level.If you're a web developer curious about IoT, this is not the right fit. If you've flashed a microcontroller, debugged a protocol with a logic analyzer, and shipped a cloud-connected product, keep reading. We are looking for recent and soon-to-be grads from postsecondary institutions who want to get their foot in the door in their industry.What You'll Work On
