Espresso Systems is the lead developer of Espresso, a global confirmation layer designed to enhance cross-chain composability by providing fast and reliable transaction confirmations. Espresso confirmations help reduce finality risk and prevent issues like sequencer equivocation, making it easier for applications to operate across multiple chains. The network is currently in its Mainnet 0 release and supports various functionalities, including fast confirmations, decentralized sequencing, and low-cost data availability. At Espresso Systems, we work with leading teams developing chains, rollups, and applications including Offchain Labs, Polygon, Cartesi, RARI Chain, and beyond—all united in our mission to build an open Web3 experience without silos for all users. The Espresso team comprises a diverse and passionate group of contributors from around the world. We are developers, designers, and researchers who have contributed in academia, in open source communities, in policymaking, and beyond. We are backed by over $50m in funding from leading investors in technology and crypto including a16z, 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.
