Arbitrum’s Operation Company (OpCo) is dedicated to supporting the growth and success of the Arbitrum ecosystem on behalf of the ArbitrumDAO. As a DAO-adjacent entity, OpCo provides the operational infrastructure necessary to empower contributors, coordinate strategic projects amongst Arbitrum Aligned Entities, and ensure the seamless execution of approved proposals.
Our mission is to serve as the connective link between the DAO’s vision and real-world execution, maintaining transparency, agility and alignment with the Arbitrum communities. We offer logistical support across a decentralized network of builders, stakeholders, and community members.

You will manage payments, conversions, and multisig operations while designing frameworks for risk management, liquidity planning, and long-term sustainability.
