We are a fully distributed team, however, we ask that some of your working hours overlap with Eastern Standard Time (EST).

As a senior software engineer, you’ll work directly with the company’s CTO, CEO, and an experienced technical team of other senior engineers, distributed systems computing experts and security experts, who are all committed to building world changing decentralized infrastructure. You’ll develop and build highly scalable, secure, and reliable software that will change the way smart contracts function at a fundamental level. You’ll have the opportunity to learn and master the latest research concerning distributed systems, cryptography, blockchains, game theory, consensus algorithms, and decentralized applications. You will be given a high level of autonomy/ownership over your projects, the opportunity to expand your scope of knowledge and the chance to help build the decentralized infrastructure of the future.

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.

Our solution and architecture are outlined 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 is a unique opportunity to join one of the top companies developing cutting-edge blockchain technology while working closely together with a team of experienced senior developers.

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).
