Senior Backend Engineer - Solana Mobile

Location: Remote (US or EMEA time zones) Type: Full-time Level: Senior IC

About Solana Mobile

Solana Mobile is building the mobile platform for digital assets on Solana. We recently launched Seeker, a digital asset–first phone featuring Seed Vault, a hardware-backed security system for wallets, along with our own wallet and the dApp Store, a mobile distribution platform for apps built by the ecosystem of Solana developers, and the Solana Mobile Stack (SMS), which enables phone manufacturers to deliver these products on their own devices.

We don't just provide infrastructure. We build the full stack across hardware, software, and platform services to deliver seamless, secure, and performant digital asset experiences on mobile.

Our backend systems power the dApp Store, wallet services, event tracking, both on-chain and within apps, on-chain transaction systems such as staking, and the APIs that developers and users rely on every day.

The Role

We're a lean, high-agency team. Engineers here own real scope: there's no large org to absorb the slack, and the decisions you make show up directly in the product. That also means we move fast and expect people to operate with a high degree of autonomy.

We actively lean into AI-assisted development as a way to keep overhead low and give every engineer more leverage. That's not specific to any one role, it's how we work. We expect engineers to experiment with AI tools, integrate them into their own workflows, and share what works. A lot of what makes us effective is how we work, and there's meaningful room to improve.

If you write solid backend systems, take ownership seriously, and want to work in an environment where your contributions have a real impact, this is it.

What You'll Own

Design and own backend architecture for core Solana Mobile services: dApp Store APIs, wallet services backend, device registry, event tracking, and on-chain activity systems (staking and related infrastructure)

Build and maintain REST and WebSocket APIs consumed by Android, Flutter, and Web clients, as well as third-party developers integrating the Solana Mobile Stack
