The Role
Develop, test, and deploy smart contracts on Ethereum, Avalanche, and Polygon while collaborating with teams to integrate them into financial applications.
Summary Generated by Built In
We are seeking an innovative Smart Contract Developer to join our growing Digital Assets engineering team.
This is a core technical hire as we expand into more sophisticated smart contract architectures powering tokenized fund operations, stablecoin issuance, and B2B2C financial services.
This is a hands-on Solidity-focused role with meaningful scope in systems design, multi-chain deployment, and smart contract integrations across compliance, liquidity, and primary markets.
As our product footprint and blockchain operations expand across chains, you’ll help shape reusable infrastructure for tokenized funds, implement best-in-class security standards, and potentially help pioneer smart contract integrations beyond Ethereum (e.g., Rust/Solana).
This role is open to candidates located in the greater New York metropolitan area or within a commutable distance.
