We are looking for a Dapp Engineer that can help us extend the DeFi capabilities of our Interlay and Kintsugi cross-chain networks. You will ship new features to our users by leveraging our existing front-end library (https://github.com/interlay/interbtc-ui/), SDK (https://github.com/interlay/interbtc-api), and GraphQL layer (https://github.com/interlay/interbtc-squid).

You are excited by the composable nature of DeFi and pushing the boundaries of Kusama and Polkadot by bringing assets like Bitcoin into the mix. You are not afraid to dive into other DeFi protocols to understand how they could enhance the Kintsugi and Interlay networks.
