It introduces you to some of the underlying principles which haven't changed much over time. I highly recommend it if you want to get deeper intuitions on the principles of CNN, LSTM/RNN, Restricted Boltzmann Machines etc. Also, Hinton's Coursera lectures, though not sure if you can access it anymore.
It seems to be listed as a software engineering position (and are likely paid through the same construct, since participants are required to be eligible for work in the US). I would think they are paid as entry level software engineers, but that's all conjecture.
