## Job description

Build the Future of Global Markets

At Arcus, we're democratizing access to financial opportunity.

The team behind Arcus previously built dYdX, one of the world's largest decentralized exchanges, helping power over $1.5 trillion in trading volume across more than nine years of experience building crypto trading infrastructure.

Now we're applying that expertise to an even bigger opportunity: bringing the world's financial markets on-chain. Today, access to markets is still limited by geography, market hours, and legacy financial infrastructure. We believe anyone, anywhere should be able to trade the assets they care about, whenever they want.

Built in partnership with Robinhood Chain and backed by a direct investment from Robinhood Crypto, Arcus is creating a unified, self-custodied trading platform where crypto, stock tokens, commodities, and perpetual futures can all be traded seamlessly from a single account, 24/7.

Our vision is simple: to make the world's markets open, always-on, and universally accessible.

Join us in shaping the next generation of global financial markets.

## About Arcus

Our team has previous experience at Google, Meta, Citadel, DRW, IMC Trading, Stripe and other top companies

We're a world-class team with top backers and advisors, including Andreessen Horowitz, Polychain Capital, Brian Armstrong, Fred Ehrsam, Naval Ravikant, Elad Gil and more
