Job description

At Offchain Labs, we are not just building products — we’re leading a movement.

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. We invite individuals with a strong interest in blockchain and a talent for approaching problems from unique perspectives to join us in shaping the future of this dynamic field.

• Work on UIs, SDKs, developer tooling, and consumer-facing applications focused on blockchain technology, onchain apps, Ethereum scaling, and Arbitrum
• Keep up-to-date on the latest technologies and developments in the space
• Communicate in a style that is open, transparent, and direct, and consistently work in tight collaboration both with your teammates and other teams
• Look for ways to help out beyond the scope of your day-to-day work

What you’ll need:

• 5+ years of hands-on full-stack engineering experience
• Mastered CS fundamentals, either through a formal university program or through self-learning
• Expertise in JavaScript and TypeScript, with strong proficiency in building web applications using React and Next.js
• Bonus: Proficiency in React Native for mobile app development
• Dabbled in, educated yourself on, or are experienced working on blockchain technology
• Track record of successfully shipping products to customers
• A strong sense of ownership in your work, which drives you to find ways to do things better and faster
• A detail-oriented approach to work, always making sure to output high-quality work through rigorous testing
• A security-first mindset, proactively identifying and addressing potential vulnerabilities in code
• A curious mind, constantly on the lookout for new technologies and innovative ways to solve complex problems through experimentation
• A collaborative, open communication style, with a willingness to embrace feedback and pursue continuous self-improvement

Perks:

• Remote-first global workforce + NY office
• Annual company offsite + team onsites
