Job Description

Senpi is the first AI Wallet - a new category of intelligent wallets that think, trade, and protect alongside users. In just four months since launching on Base, Senpi has processed 285K+ AI auto-trades , achieved a b (~3× higher than typical exchanges), and welcomed 200+ traders to the “1000% Club.”

At Senpi, you won’t just be joining another startup — you’ll be helping reinvent the wallet itself into the intelligent agent of onchain finance.
