Zellic is hiring Cryptographers and Zero Knowledge experts. We're looking for individuals with outstanding talent in cryptography, applied and pure math, zero knowledge proofs, multi-party computation, and fully homomorphic encryption. You'll collaborate closely with our cryptography team and the world's best hackers to secure critical infrastructure, with a focus on zero knowledge systems and cutting-edge research on the security of new cryptographic primitives.
About Us
We do the best security reviews in the world. Our clients include Polymarket, Canonical, Protonmail, Cognition, and the Solana Foundation. Before Zellic, we previously founded perfect blue, the #1 CTF team in 2020, 2021, and 2023 as part of Blue Water.
We are an employee-owned company. We’re consistently profitable, with a team of 50+ and growing (mostly CTF players). We value steady, long-term success over short-term gains.
Responsibilities
- Conduct security assessments and audits of zero knowledge circuits and systems to identify security or design flaws
- Communicate assessment findings with clients in a clear and professional manner
- Perform research and write about the of state of art blockchain cryptographic primitives.
- Opportunity to travel and present at security conferences.
- Stay up-to-date with the latest advancements in zero knowledge cryptography
Qualifications
- Strong background in cryptography, including experience in designing cryptographic protocols and primitives. Bonus points for breaking them!
- Familiarity with zero knowledge proof systems, such as SNARKs, STARKS or Bulletproofs
- Experience in programming languages and DSLs commonly used in zero knowledge cryptography, such as Rust and Circom
Other Nice-To-Haves
- Experience in formal verification methods and security for zero knowledge circuits. This is welcome but not required. Many of our hires come straight from a pure math PhD.
- Competed in CTFs with focus on cryptography challenges
- A healthy dose of skepticism and the ability to think independently and critically
- An interest in finance or blockchain is welcome but not required. Many of our hires have no prior blockchain experience.
