API Integration Tooling Developer

API3 builds blockchain-native, decentralized APIs with DAO-governance and quantifiable security. We have recently raised a high profile seed round, executed a public distribution, and are now looking to fill some key roles in our core technical team.

Airnode is a serverless oracle node designed to be operated by API providers, and will act as a gateway between traditional Web APIs and smart contracts running on blockchains. You will develop tooling that will streamline the integrations and their validation.

You can refer to the API3 whitepaper and our Airnode article for more information.
