levels.fyi shows $498,910 in total compensation for a staff level SWE at Google. Different companies compensate using a different blend of cash and equity. At a public company like Google, it's all liquid. Similarly, an E6 at Facebook gets $576,886.
These are also roughly speaking first-year salaries. You can expect a refresh grant equal to 1/4 of a new-hire equity grant each year vesting over 4 years, plus a staff-level can get a signing bonus of $50-100K.
After 3-4 years in a staff role you can easily be making $1-2M/yr.
It's probably not 380K base, which is very high, it's likely 300K base + 25% bonus target = $375K, give or take. That's not hugely more than any of the mega-caps have been paying in cash comp for staffie's for like 5+ years.
