Senior Software Engineer

Offchain Labs is building a suite of scaling solutions for Ethereum. This includes Arbitrum, an Optimistic Rollup, that instantly scales apps, reducing costs and increasing capacity, without sacrificing Ethereum’s security. Porting contracts to Arbitrum requires no code changes or downloads since it’s compatible with existing Ethereum developer languages and tooling.

Our team is extremely passionate and works tirelessly to bridge the gap between what blockchain is and what blockchain can be. We strive to maintain an atmosphere that fosters innovation and new ideas through collaboration, research, and deep discussions. After raising an initial round of $3.8M in seed funding in January 2019 and a $20M series A, as well as a $100M series B in 2021, we are ready to hire additional team members that have an interest in working in the blockchain space and a knack for approaching problems in unconventional ways.
