Builders interested in joining the Guild team and sharing their skills are always welcome. Currently, we are a centralized group of developers and non-tech builders, working closely together on-site in Hungary. Therefore we don't have any developer opportunities or bounties available at this time.
However, you can still contribute by building on top of Guild API & SDK. It's an impactful way to make a difference with us, so feel free to give it a try and show what's possible with Guild.
