About the job

What You'll Do

  • Own and evolve Solana programs end-to-end — from development through deployment and maintenance
  • Build robust, scalable backend services that interact with Solana, EVM, and Stellar networks
  • Scale our on-chain infrastructure to support millions of users globally — powering transactions, data ingestion, and real-time processing
  • Play a central role in shaping the technical and product roadmap
  • Drive architectural decisions in a fast-moving, rapidly evolving product
  • Ship new capabilities quickly and iteratively to our customers

What We're Looking For

  • Deep expertise in the Solana ecosystem, including its programming model, tooling, and best practices
  • Strong proficiency in Rust
  • Solid understanding of smart contract security patterns and common vulnerability classes
  • Experience with Node.js and backend systems
  • 2–10+ years of engineering experience; compensation will be calibrated accordingly

Nice to Have

  • Fintech experience — neobank or card issuing background gets extra brownie points
