About the role

  • This role sits at the intersection of research and engineering.
  • Your focus is on the cryptographic foundations that make Char's protocol secure and efficient: designing and analyzing commitment schemes, aggregation protocols, proof systems, and fork-free coordination mechanisms.
  • This is not a pure theory role, you'll write code.

Responsibilities

  • Design and analyze cryptographic schemes: BLS proof-of-stake commitments, signature aggregation protocols, hash-based accumulator designs, and zero-knowledge proof systems for Bitcoin anchoring
  • Develop and validate cryptographic implementations: work with the protocol team to guide BLS Purify integration, verify protocol specifications against implementation, and conduct security reviews
  • Build simulations and prototypes in Rust or C++ to validate cryptographic protocol designs under adversarial conditions: analyze safety/liveness and attack resilience
  • Deep expertise in applied cryptography: signature schemes, commitment schemes, zero-knowledge proofs, or cryptographic protocol design
  • BLS proof-of-stake commitments, signature aggregation protocols, hash-based accumulator designs, and zero-knowledge proof systems for Bitcoin anchoring
  • Build simulations and prototypes in Rust or
  • signature schemes, commitment schemes, zero-knowledge proofs, or cryptographic protocol design

Requirements

  • Ability to move between theory and practice: formal reasoning, mathematical modeling, and implementation
  • Exceptional communication skills-you can explain complex cryptographic ideas clearly to both researchers and engineers
  • PhD or equivalent research experience in cryptography, distributed systems, or a related field
  • Experience with formal verification, model checking, or advanced testing frameworks
  • Experience with game-theoretic analysis or mechanism design (helpful for understanding protocol incentives)

Nice to have

  • Miami, FL strongly preferred ·

Skills

  • Strong programming skills in Rust or C++ (or equivalent systems languages)
  • Experience designing, analyzing, or breaking adversarial cryptographic protocols or consensus systems
