Espresso Systems is the lead developer of the Espresso Sequencer, which supports rollups with decentralization, scale, and interoperability.
The Espresso Sequencer supports the decentralization of layer-2 (L2) rollups in the Ethereum ecosystem and beyond. It handles the decentralized sequencing and data availability of rollup transactions, functioning as a middleware between underlying layer-1 (L1) platforms and any zkVM or optimistic VM.
Contributors to Espresso comprise a diverse team located around the world. We are passionate about building a better infrastructure for how we transact and interact online. We are builders, designers, researchers, and hackers and have contributed in academia, in open source communities, in policymaking, and beyond. We are backed by over $30mm in funding from leading investors in technology and crypto including Greylock Partners, Electric Capital, Sequoia Capital, and Polychain Capital.
As a smart contract software engineer, you will closely collaborate with fellow engineers and researchers to build the blockchain infrastructure needed to bring Espresso's scalability infrastructure to the Ethereum ecosystem. Examples of work include implementing smart contracts to manage the HotShot proof-of-stake consensus mechanism underpinning the Espresso Sequencer and utilizing our cryptographic primitives to verify the Espresso Sequencer's state efficiently on the blockchain.
