I'm a guy with an undergrad degree, no graduate degrees, and no formal training in big data nor ML (just good old fashioned systems programming) and I'm in/above that range.

The key is to know how to negotiate - and also realizing that half of the negotiation is done before you get to the table. Nobody is going to volunteer paying a SWE $600K, but they can be compelled to do so if you know how.

Happy to share knowledge here - I'm firmly of the opinion that you should be paid the absolute maximum of what your employer will bear. They aren't leaving money on the table in their deals, so neither should you.
