About the role

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.
A lot of what makes us effective is how we work, and there's meaningful room to improve.

Responsibilities

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
Collaborate with mobile engineers (Android/Kotlin, Flutter/Dart) to design mobile-first API patterns - offline resilience, background sync, efficient payloads for constrained networks
Work closely with Protocol Engineers, building Solana programs to design off-chain services that compose cleanly with on-chain logic
you take problems end-to-end and drive them to resolution without waiting for direction
schema design, query optimization, indexing, migration discipline
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.
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)

Requirements

5+ years of professional backend engineering, with a track record of owning and operating production services
Good working knowledge of Redis: caching patterns, pub/sub, TTL strategies

Skills

Strong proficiency in TypeScript/Node.js and/or Rust - idiomatic, well-tested, production-grade code
ECS, RDS, SQS, S3, Lambda - comfortable deploying and operating services in a cloud environment
