It's been a few years, but from what I recall, a Principal is a Director-equivalent (L8) level.
The prior poster is missing the L7 tier, which is Senior Staff Engineering Manager for the Engineering Manager Ladder.
L8 is a Director on the Engineering Manager Ladder
L8 is a Principal on the Software Engineer (SWE) Ladder.
Tech-Lead Managers (TL/M or TLMs) were on the SWE Ladder.
For reference:
Software Engineer Ladder
L8 - Principal Software Engineer
L7 - Senior Staff Software Engineer
L6 - Staff Software Engineer
L5 - Senior Software Engineer
L4 - Software Engineer II
L3 - Software Engineer (new graduates would start here)
----------------------
L2 and below exists in rare occasions.
Engineering Manager Ladder
L8 - Director
L7 - Staff Engineering Manager
L6 - Engineering Manager (M1)
L5 - Engineering Manager (M0 - normally this level does not exist for external hires and is for the rare situation when a SWE is converting to the Engineering Manager ladder)
One of the problems is that large corporations have such complicated role structures, and another problem is that they are also different from all other large corporations. A third problem is that the compensation models are again vastly different. A fourth problem is that they change over time.
All of this means as an individual you suffer from extreme information asymmetry.
Even if you got two offers from two different FAANGs, it would perhaps be hard to figure out which one is better.
Has anyone defined any mapping tables between role names across Amazon, Meta, Alphabet etc. and figured out salary ranges for them in a public spreadsheet?
BTW, has anyone got a leaked (anonymized) copy of FAANG employment contracts so one can compare the various clauses across employers, and track changes of their standard templates over time? (I haven't seen this topic discussed much on here in the systematic way that it deserves.)
Given the developer community invented open source it is surprising that corporations have so far succeeded in keeping such obvious things relatively secret (compared to, say, the emails of Sarah Palin and Ehud Barak ;-).
This is not really an accurate representation of FAANG hiring and job searching. In reality, there is a very very high amount of job hopping and also connections to people at other FAANGs (and there's also levels.fyi and blind) so we're well aware of comp structures, what employment agreements, levels, etc are across companies and how to compare then. There's very little information asymmetry in fact people go into negotiations with recruiters very well equipped, far better than at small companies.

If this doesn't exist it's only because it's incredibly uninteresting. levels.fyi will tell you all you need to know. (also they aren't employment contracts, in the US we do agreements because we're at-will)
I've hopped multiple FAANG+s now across my career.
Senior engineer is usually focused on a single project, and knows it deeply. Usually directing and mentoring more junior engineers in the process.
Staff engineer typically is overseeing multiple projects, providing deep technical oversight and guidance on those projects, and mentoring Senior engineers. They start to influence technical culture. They are actively involved in ensuring business needs get met by the technical solutions their group is building.
Senior Staff Engineers will be overseeing a product function, and multiple Staff engineers. They build the correct technical culture. They ensure larger architectural issues get resolved. They are actively involved in ensuring the technical work being done is meeting business needs, and identifying business needs their technical org can be meeting - and working to make that happen.
Principal engineers are setting the tone for an entire large product (typically), and ensuring the Senior Staff engineers are doing the right things - and also often involved in driving strategic product direction.
Senior Staff and Principal tend to be increasingly political, but even Staff will get pulled into that type of thing somewhat regularly.
