📋 Description

• 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 • Own your services in production: participate in on-call rotation, author runbooks, contribute to post-mortems, and close the loop on action items • Look for friction in your own work and in the team's processes: automate what makes sense, build small tools that save repeated effort, and share what you build • Contribute to CI/CD reliability and build infrastructure (GitHub Actions, WarpBuild) with a sharp eye on pipeline speed, cost, and reproducibility • Conduct thorough code reviews, contribute to technical discussions, initiate RFC discussions for significant changes, and help the team get better over time • Drive infrastructure decisions on AWS (ECS, RDS, Lambda, SQS, CloudFront) — from architecture through to cost-conscious production operation • Own the observability stack: structured logging (Loki), metrics and alerting (Prometheus, Grafana Unified Alerting), distributed tracing, and incident response runbooks • Contribute to backend architecture for device attestation and the Seed Vault integration layer, including on-chain verification flows (Squads Protocol multisig, SPL token operations) • 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

🎯 Requirements

• 5+ years of professional backend engineering, with a track record of owning and operating production services • High ownership: you take problems end-to-end and drive them to resolution without waiting for direction • Proactive by default: you identify issues early, propose solutions, and move quickly • You already use AI coding tools (Claude Code, Cursor, Copilot) as part of how you work: not as a novelty, but because they make you faster and you've figured out when to trust them • Strong proficiency in TypeScript/Node.js and/or Rust — idiomatic, well-tested, production-grade code • Solid command of PostgreSQL: schema design, query optimization, indexing, migration discipline • Good working knowledge of Redis: caching patterns, pub/sub, TTL strategies • Hands-on AWS experience: ECS, RDS, SQS, S3, Lambda — comfortable deploying and operating services in a cloud environment • Sound understanding of distributed systems: idempotency, eventual consistency, fault tolerance, graceful degradation • Security-aware: secrets management (AWS Secrets Manager / SSM), API auth patterns (JWT, OAuth2), OWASP hygiene • Comfortable with Docker and containerized deployments.
