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.
