About Us

Smart contracts are on track to revolutionize how all agreements work, through an entirely new system of cryptographically-enforced contract guarantees. Chainlink enables next-generation smart contracts that can be written about any/all events in the real world. We live by an open source ethos and believe in giving back to the community.

Smart contracts are on track to revolutionize how all agreements work, through an entirely new system of technologically enforced contract guarantees. Chainlink enables next-generation smart contracts that can be written about any/all events in the real world, the details of our approach can be found in our whitepaper. We are well recognized for providing highly secure and reliable blockchain connectivity to the world’s largest enterprises such as Google, Oracle, SWIFT, and many more.

This role is location-agnostic, and we employ engineers worldwide. However, we ask that some of your working hours overlap with Eastern Standard Time (EST).

Chainlink is an Equal Opportunity Employer.
