Splatoon 3 is set for launch sometime in 2022, and Nintendo is hard at work piecing the game together right now. It looks like the Big N needs a bit more help with the project, as they're looking to take on a new level designer.
Nintendo posted the job listing just yesterday, and they're looking to bring in someone who can help create new levels and also adjust some that have already been created. They also need the new employee to help out with overall game balance. You can have a look at the listing here.
