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 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.
The Role :
To build the next chapter of Solana Mobile, we are seeking a Senior Protocol Engineer to join our team full‑time. The ideal candidate is a highly organized, versatile individual who will build and ship Solana programs that will drive Solana Mobile’s ecosystem and adoption of the next generation of Solana Mobile developers and users.
The core responsibility of this role is to build and own Solana programs that are instrumental for the health and growth of the Solana Mobile ecosystem. You will build unique on‑chain programs for token operations, including staking, voting and governance. You will work with backend engineers to build infrastructure and APIs to connect users, developers and decentralized gate‑keepers of the Solana Mobile device ecosystem. You create efficiency for operations by stream‑lining the monitoring of performance, stability and security of Solana Mobile’s infrastructure.
Key Responsibilities :
- Build and ship new Solana on‑chain programs for staking, voting and governance, based on Rust.
- Create new APIs to securely interact with on‑chain programs.
- Enhance the speed, performance, and reliability of existing web‑based services driving the mobile application store and other core services.
