Lead Security Engineer – NFT Infrastructure

Lead Security Engineer – NFT Infrastructure

Sydney / Relocation / Remote


Unique blockchain assets (“NFTs”) are experiencing a massive surge in popularity. These unique assets allow people to own anything from in-game items, to digital art, to music, and financial instruments.  However, they are highly illiquid: transactions take minutes or hours to confirm, and Ethereum can process fewer than 5 NFTs per second for the whole world combined. To solve this problem our client has built, a next-generation protocol for trading blockchain assets with instant trade confirmation, massive scalability, and no gas fees without compromising user custody. The goal is to help businesses scale their creation and trading of these unique assets (“NFTs”).
