Software Engineer

About the Role

You'll design, build, and maintain Solana programs and the backend services that integrate with them, while contributing to shared infrastructure across EVM, Solana, and Stellar. Our platform powers crypto-backed card products — processing high transaction volumes, continuously ingesting on-chain data, and navigating the unique complexity of each chain, with scalability and reliability engineered in from day one.

Key Responsibilities:

• 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

Requirement:

• 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.
