In a world beset by plummeting trust, Scroll is building the trust layer to power the next phase of the Internet, using state-of-the-art math and cryptography.

About Scroll…
Scroll is building an open source, bytecode level compatible zkEVM layer 2 solution for Ethereum. Our mission is to scale Ethereum while maintaining our values of credible neutrality, openness, and community driven.

About the Job

  • We’re hiring a Protocol Engineer to serve as a foundational member of a new Protocol team, dedicated to keeping Scroll at the very forefront of blockchain and Ethereum innovation.
  • This hire will own and lead projects that ensure Scroll continues to differentiate itself, and pushes the boundaries of zkRollup technology.
  • The Protocol Engineer will design and implement features in production, and will contribute to and have a massive impact upon the broader Ethereum ecosystem.
  • You will work at the forefront of the industry, on massively complex problems, like decentralizing the sequencer.
  • You will do it alongside other deeply driven technical minds, in a culture defined by and dedicated to autonomy, ownership and openness. And you will have the chance to collaborate externally with thinkers and researchers in academia and other leading blockchain organizations.
  • This is a fully remote job.


  • Demonstrated ability to design and implement new, production-ready, open-source blockchain protocol projects using Golang or Rust and good understanding of Solidity. For instance, by having contributed to Ethereum, authored and implemented EIPs, published/commented on ethresear.ch, pushed PRs to nodes like geth or Lighthouse, EF fellowship, and/or written academic papers, etc.
  • You take ownership, and operate proactively, independently, and with openness and transparency. Confident but humble and low ego, your excitement over learning complex concepts motivates and inspires others.
  • You enjoy collaborating with others and excel at communicating with them, asynchronously and across cultures. You speak and write (documentation and specs, as well as on Slack), clearly and concisely.
  • Excellent coding standards (distributed systems, open source, correct and performant code, good developer practices, effective use of Notion/GitHub, performance profiling, optimization, correct + robust + maintainable code).
