We are looking for a highly experienced Senior Backend Engineer to work fully remotely for a company in the crypto industry.
About the company
Our ecosystem is a self-sufficient DeFi economy utilizing stablecoins as currency. We currently have three: one pegged to the US dollar (FRAX), one pegged to the inflation of the US dollar (FPI), and one pegged to ETH (frxETH/sfrxETH) that earns yield from Ethereum staking (a liquid staking derivative).
We have also developed unique swap (Fraxswap), lending (Fraxlend), bridging (Fraxferry) and other features for these. Additionally, we recently launched our own chain, Fraxtal (based on the OP Stack), with frxETH as the gas token.
We are a top 100 crypto company by combined market cap (FRAX, FXS, frxETH, and sfrxETH).
