Senior Mobile Software Engineer

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.”

Backed with $4M in Seed capital by top investors including Lemniscap, Coinbase Ventures, and SuperLayer, we’re building on a track record of OG Ethereum innovation — from creating one of the first smart wallets approved by Apple to pioneering AI blockchain search.

With millions in trading volume and 75%+ retention already, we’re now rolling out iOS and Android apps, expanding multi-chain, and pushing deeper into perps, futures, and yield strategies. 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.

We’re looking for a Lead Mobile Engineer to own and scale Senpi’s iOS and Android apps, taking them from 1→100 and shaping the most intuitive crypto trading experience on mobile.
