About the Role

You'll design, build, and maintain EVM smart contracts 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.

What you'll do

• Own and evolve EVM smart contracts end-to-end - from development through deployment and maintenance
• Build robust, scalable backend services that interact with EVM, Solana, 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 EVM ecosystem, including smart contract development, tooling, and best practices
• Strong proficiency in Solidity
• Experience with development frameworks such as Hardhat or Foundry
• Solid understanding of smart contract security patterns, common vulnerability classes, and gas optimization
• Experience with Node.js and backend systems
• 2-10+ years of engineering experience; compensation will be calibrated accordingly

Nice to have, but not mandatory

• Fintech experience - neobank or card issuing background gets extra brownie points
• Experience deploying across multiple EVM-compatible chains (Ethereum, Arbitrum, Base, Polygon, etc.)
• Familiarity with upgradeable contract patterns and proxy architectures
