Our Ethos

We believe in an open and flat structure. You will be able to grow into the role that most aligns with your goals. Our team members at all levels have the freedom to explore ideas and impact the roadmap and vision of our company.

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.

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.
