About the TeamYou'll be the lead iOS engineer at Rain, owning mobile alongside the lead Android developer from the ground up. Our partners use Rain's issuance platform and APIs to power card programs, wallets, and payment experiences for their end users, and you'll be the person who brings those experiences to life on iOS. You'll work directly with product, design, and our platform engineering team to define what great mobile looks like for Rain's clients and their customers.
