alt Hacker NewsAs others have said, levels and titles are generally for compensation and performance reviews. Each company has their own bespoke ladder but it generally maps to:
- L1: Intern with undergrad degree
- L2: Intern with graduate degree
- L3: Junior
- L4: Intermediate
- L5: Senior
- L6: Staff
- L7: Senior Staff
- L8: Principal
- L9: Distinguished
- L10: Fellow
L5 or Senior is usually considered a “terminal” role. That means all engineers should be able to get to this role. And people without the headroom get managed out if they can’t get to L5.
Staff+ is usually “special”. It means that people count on you to drive initiatives and you have something special other than just writing code. You are able to make product and business impact.
Distinguished and Fellow are very rare. Large FAANG companies will only have a handful of these engineers. It means you’ve made industry-wide impact like inventing map-reduce or DynamoDB or Kubernetes.

This does remind me somewhat of military command structures with L1-L5 being enlisted ranks and L6-L10 either being NCO or Commissioned depending on your view of how much gatekeeping is involved.
At Microsoft I would map your L6 to Principal, and L7/L8 to what we call "Partner". I'm a Principal, but I'm definitely not an 8 out of 10 yet.

But the big difference, I believe, is that being at the top of a ladder in one company may be completely different from being at the top in another one.
It's easy to be the CTO of a company of 2, much harder for BigTech. Even if the company of 2 has the same levels.
I have met people being very very proud of their title of CTO, and when I asked, their company had a handful of developers.
You're describing a very small number of companies that all copied each other's systems. The idea of a terminal role, for example, is pure Facebook. These do not apply in general across the industry except where managers from those small number of companies came in and shoved them in before they were fired.
