You may be a fit for this role if you have:

  • Experience designing, building, and operating blockchain protocols, decentralized peer-to-peer networks and their incentives or consensus mechanisms.

  • Technical leadership experience in any of the above.
  • Deep understanding of decentralized peer-to-peer systems principles and applications.
  • Deep understanding of cryptography principles and applications.
  • Strong technical design ability informed by broad experience across multiple domains.
  • Excellent communication skills on technical and non-technical topics, with an emphasis on clear and concise written async communication

Not required, but a bonus if you have:

  • Experience with security or privacy engineering.
  • Experience designing and building large-scale distributed web systems in production.
  • Experience contributing to open-source projects, or leading development efforts within open-source communities.
