Most companies don't pay that, step 1 is identifying the companies that do and focusing your efforts on them exclusively. This will depend on where you live, or on your remote opportunities.
Step 2 is gaining the skills they are looking for. Appropriate language/framework/skill/experience they optimize for.
Step 3 is to prepare for their interview process, which is often quite involved. But they pay well, so when they say jump, you jump.
I'm not saying you'll find $600k as a normal pay, that's quite out of touch unless you're in Silicon Valley (and even then). But you'll find (much) higher than market salary.
