We are distributed across time zones and continents, and we embrace remote work. Our on-call rotation uses the follow-the-sun pattern: you will be on-call some of the time, but your shifts will be during your day and our team is large.
We all have different backgrounds and are determined to help you succeed no matter where you are or who you are. If you think you would do a great job at Chainlink, we are looking forward to speaking with you, even if you don't match 100% of the job requirements: those describe people we've usually had a great time working with, but they're not a tick-box exercise.
