We are looking for a blockchain infrastructure engineer to help build the sequencer client for our fully EVM-compatible zkRollup based on a zkEVM. To maintain full compatibility, our client is a fork of Geth with many alterations to integrate with our decentralized proving network.

Your day-to-day work will involve getting hands on with Geth internals, interfacing with cutting-edge zero-knowledge proof technologies, and optimizing across the stack. We are looking for someone with a deep understanding of blockchain infrastructure as well as software engineering best practices. The ideal candidate will be able to optimize performance while maintaining a code correctness in a high-stakes development environment.

Scroll is proud to be an equal opportunity workplace. We are committed to equal employment opportunities regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity, or Veteran status. If you have a disability or special need, please let us know and we'll do our best to accommodate.

Job Duties

    • Writing Golang client code for our sequencer client.
    • Interfacing with the zkEVM team to ensure compatibility between the client and the prover network.
    • Writing networking code to interface between the sequencer and the proving network.
    • Testing for full EVM compatibility.
    • Rigorous security auditing and testing of the sequencer.


    • Fluency in Golang, Rust, C++, or similar languages. We work primarily in Golang.
    • Knowledge of common algorithms, data structures, and their computational and memory complexities, as well as experience implementing them from scratch.
    • Deep understanding of some aspect of blockchain protocols (consensus, p2p, EVM) and their implementation.
    • Experience writing security-critical production code.
    • Good (async) communication skills and ability to work with a globally distributed multicultural team.

Preferred Qualifications

    • Experience in blockchain infrastructure development or cryptography.
    • Familiarity with go-ethereum or a similar codebase.
    • Experience with zkRollups or other L2 technologies.
    • Prior experience in performance optimization.
    • Proven record of high quality open-source contributions. (Please share links to prior PRs when possible.)
