Does Coinbase offer sign on bonus ?

No lol

Yes it does. They don’t negotiate TC but sign on can be negotiated. the signon will be to make you whole on the money you would be losing in joining CB.

Is coinbase hiring again?

Yes, depends on your set of skills, there’s a rubric for what’s eligible, e.g. react native experience

Yup - say you have a competing offer and you won’t sign unless you get 10-15% sign on

joined few years back, IC5 HCOL sign on for me was a bit north of $50k
