Android System Engineer

Who We Are

Solana is a high performance blockchain that can deliver a fast and friendly user experience, without sacrificing security. 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 hardware-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.

Solana Labs, Inc. ("Solana Labs") is a technology company that builds products, tools, and reference implementations that can be used on the Solana blockchain. Solana Mobile is a dedicated team within Solana Labs. We are a fully distributed team with offices in San Francisco and New York.
