Hello, would you consider a candidate from the China?

Hi @chaichai , we require teammates to be online 09:00 UTC–15:00 UTC for effective communication, and we don’t recommend candidates to apply if this will be prohibitive to having a healthy schedule. Otherwise, we don’t have a preference about where teammates reside.

I am interested

core hours its when the team its connected, means that i need stay the full range or my schedule can match with the range in some part, for example i can start in the mornings and work the last 3 hours of the range and the rest after the daywork ends

this its viable for the team? how much time must be worked inside the range of time?

@apoorv-2204 see the original post for the contact info

@nicolkill we prefer a 100% overlap but relevant domain experience (especially with EVM) reduces the need for real-time communication, so this is negotiable in some cases
