We are committed to creating a decentralized, secure, and transparent future through blockchain technology. Our mission is to push the boundaries of blockchain innovation and foster a creative, collaborative, and inclusive culture where ideas can come to life. We know that the future of blockchain technology is limitless, and the best way to achieve this is by working with the brightest minds.

We’re looking for thinkers and doers who are eager to embrace new challenges and seek solutions that will push existing boundaries. If you believe in the importance of transparency, trust, and the decentralization of control, and if you’re curious, adaptable, and want to disrupt the status quo, then we want to hear from you.

Why Offchain Labs?

Our team is committed to bridging the gap between the current state of blockchain and its potential. Our flagship product, Arbitrum One, is a dominant force in Ethereum scaling and is trusted by enterprises, developers, and users worldwide. But that’s just the beginning. Our passionate team is constantly building on this success, rolling out innovative tools such as Arbitrum AnyTrust, Arbitrum Orbit, Stylus, BoLD, and Arbitrum Nitro. Offchain Labs also contributes to the Ethereum core protocol with the Prysm consensus client.

Following the successful raising of $3.8M in seed funding in January 2019, as well as $20M in Series A and $100M in Series B funding in 2021, we are looking to expand our team.
