Senior Backend Engineer - Remote, AI-Enabled Blockchain

Solana Labs, Inc.; Northern (KY); Hybrid; USD 140,000 - 190,000; Full time

Job summary

Solana Labs, Inc. is hiring a Senior Backend Engineer for Solana Mobile to design backend architectures, build APIs, and own services in production with on-call responsibilities.

You’ll work with TypeScript/Node.js and Rust, PostgreSQL, Redis, and AWS, collaborating with mobile engineers to deliver scalable, secure mobile-first backend solutions in a remote-friendly setup across US or EMEA time zones.

Qualifications

• 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.
• 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.

Responsibilities

• 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
