Probably similar to a typical startup engineering job. Lots of these exchanges started with little funding or were originally hacked together in a basement. Then they grew very quickly and suddenly had budget to hire serious engineering teams.

I assume you’d deal with supporting lots of buggy legacy code, either fixing bugs or refactoring. You could also be working on a new green field code to replace the old platform. Or anything in between.

They also seem to have trouble scaling and keeping their servers running during peak times. Assume there’s a ton of dev ops work as well as optimisations and performance tuning / scaling related engineering going on.

Finally, since these exchanges keep peoples’ cryprocirrencies On hot and cold wallets they probably have a lot of engineering resources focused on security.
