The top of the range you're quoting is for a typical Staff Software Engineer at Google/Facebook/Microsoft. "Top ML experts" garner much, much higher comp packages.
Yeah these ranges are such a joke. Top new grads at Google are getting comp packages along the lines of 115 base, 450 RSUs / 4 years, 60k signing, 15% bonus these days. L5s regularly make 400k+ all in.
The obvious reality is that top people rarely talk about their comp packages, as there is no reason to rock the boat.
Are these numbers for real, and are these all Bay Area? I'm further North and pull no where near these numbers as an ML PhD with a lot of experience now in the tech industry. Have I goofed on all negotiations?
Probably real, yes only Bay Area, and no not the norm for ML.
First of all only a few companies can pay that much (Google, Facebook, LinkedIn, Netflix, etc) and these are outliers. The average ML engineer in the Bay Area does not make 500k/yr total comp.
ML engineer is a programmer usually with a BS in CS, sometimes​ a MS. They are, in the end, only an engineer.
The AI scientists, those with work in computer vision, natural language, and audio, developing novel networks and training methods, make at least $500K/year. I've been a data scientist and the pay (and work content) was a joke. I switched to AI and damn, work makes you think and you get paid like a mid-range NBA star.
Fei Fei Li said Karpathy was offered more than a million out of school by an unnamed firm. One can only imagine what people like Alex Graves Ann's Nando get paid...
