Optimism is building open-source software to scale Ethereum using zero-knowledge proofs. Its main product is the OP Stack, a modular blueprint for scalable, interoperable blockchains. In 2022, Optimism saw strong growth, with over 35 new dApps launched and total on-chain value growing to over $800M. More recently the company has benefited from resurgence in cryptocurrency trading in early 2024.

Optimism's co-founders bring deep expertise in blockchain engineering and research. CEO Jinglan Wang previously led product at Plasma Group, while other co-founders held key roles at Coinbase and the Ethereum Foundation. The company has raised funding from top investors like a16z and Paradigm.

By joining Optimism, you would have the opportunity to work on cutting-edge blockchain scaling technology with the potential to become a core part of Ethereum infrastructure. The team of around 50 has an academically-oriented, research-driven culture united around the ambitious mission of helping Ethereum compete with centralized tech platforms. However, Optimism faces significant competition from other prominent Layer 2 solutions like Arbitrum and technical risks in implementing zero-knowledge proofs.
