Trust Wallet isn’t just another crypto wallet; it powers a user base that spans hundreds of millions across more than 100 blockchains. The Senior Mobile Engineer slot sits at the heart of that ecosystem, responsible for the end‑to‑end experience users have on iOS and Android. What sets this role apart is the blend of deep React Native expertise with an expectation to influence shared UI components that ripple through both mobile and web products.
