Senior Backend Engineer · Solana Mobile

Who We Are

Solana is a high-performance blockchain that can deliver a fast and friendly user experience, without sacrificing security. Solana Labs, Inc. is a technology company that builds products, tools, and reference implementations that can be used on the Solana blockchain.

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 dApp Store, a mobile distribution platform for apps built by the ecosystem of Solana developers.

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 off-chain), and the core APIs that developers 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. We expect engineers to experiment with AI tools (Claude Code, Cursor, Copilot), integrate them into their own workflows, and share what works. 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

• Architecture Engineering: Design and own backend architecture for core Solana Mobile services: dApp Store APIs, wallet services backend, device registry, and on-chain activity systems (staking and related infrastructure).
• API Distribution: 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.
• Production Reliability: Own your services in production: participate in on-call rotation, author runbooks, contribute to post-mortems, and close the loop on action items.
• Infrastructure Strategy: Drive infrastructure decisions on AWS (ECS, RDS, Lambda, SQS, CloudFront) from architecture through to cost-conscious production operation.
• Observability Matrix: Own the observability stack: structured logging (Loki), metrics and alerting (Prometheus, Grafana Unified Alerting), distributed tracing, and incident response runbooks.
