Solutions Engineer,

The financial system still runs on infrastructure built for a different era. Slow settlement, extractive middlemen, economics you don't control. OP Labs is the team changing that.



We build the technology behind Optimism — the infrastructure already powering 65% of all Layer 2 activity on Ethereum. Our open-source OP Stack lets developers and enterprises launch their own scalable, secure, customizable onchain networks. Through OP Enterprise, we give companies fully managed blockchain infrastructure — their chain, their revenue, their rules. Through OP Mainnet, we run the most battle-tested public network in the ecosystem, where the hardest problems get solved first.



Sony did it. Kraken did it. OKX did it. 50+ enterprises in production and counting.



Backed by a16z, Paradigm, and others, we've raised over $175M. The next generation of financial infrastructure is being built here. Come build it with us.
