  • Use and extend circuit Software Development Kits (SDKs) to accelerate development
  • Develop reusable circuit components and SDKs to support new token standards
  • Add new functionality, extend existing functionality, and maintain high-speed cryptography libraries like Nova
  • Upgrade proof systems to include recent developments/optimizations
  • Parallelize proof generation across machines
  • GPU-based optimization of proving process
  • Embody our culture and values

Requirements:

  • Bachelor's Degree in Computer Science or related technical field AND 4+ years technical engineering experience with coding in languages including, but not limited to, Rust
  • OR equivalent experience

Nice to have:

  • Doctorate (PhD) or Master's Degree in Computer Science or related fields
  • Prior experience with ZK circuit development using frameworks like Bellpepper, Circom, or Arkworks
  • Familiarity with blockchain token standards
  • Familiarity with state-of-the-art proof systems
