Senior Protocol Engineer

Who We Are:

At Solana Mobile, we are working to bring Solana and web3 to the palm of your hand on mobile. In 2023 we shipped the Saga phone with Seed Vault to secure Solana wallets with HW backed security and built the dApp Store as a developer friendly place to bring web3 apps to users. We also implement and provide the Solana Mobile Stack to developers to simplify building web3 dApps for mobile. In 2025 we continued this journey with the release of Seeker, which has shipped to 150k customers in 50+ countries.
