This role offers the opportunity to work at the forefront of blockchain security and cryptographic research, focusing on the evaluation and auditing of zero-knowledge systems that power next-generation decentralized applications. You will be responsible for analyzing the correctness, soundness, and security of complex cryptographic protocols across cutting-edge ecosystems. The position combines deep theoretical cryptography with hands-on engineering, requiring close collaboration with researchers, protocol engineers, and clients. You will contribute to strengthening the security of high-impact blockchain systems while helping design and improve advanced auditing tools. The environment is highly technical, research-driven, and fast-evolving, with constant exposure to new cryptographic innovations. This is a unique opportunity to directly influence the security and reliability of foundational Web3 infrastructure.
Accountabilities
- Conduct in-depth security audits of cryptographic protocols, zero-knowledge systems, zkDSL circuits, and zkVM guest programs.
- Evaluate correctness, soundness, completeness, and privacy guarantees in ZK-based implementations.
- Review production-level code across Ethereum, Layer 2, and other blockchain ecosystems to identify vulnerabilities and propose fixes.
- Collaborate with security engineers and researchers to improve internal auditing methodologies and tooling.
- Design and develop new tools for analyzing and securing cryptographic and zero-knowledge systems.
- Stay up to date with emerging ZK frameworks, proof systems, and cryptographic attack vectors.
- Participate in client discussions to present findings, recommend mitigations, and support remediation efforts.
- Contribute to internal research documentation and knowledge sharing initiatives.
Requirements
- 1+ year of experience in security auditing, cryptography, or zero-knowledge systems.
- Degree in Computer Science, Cybersecurity, Mathematics, or a related technical field.
- Strong understanding of cryptographic principles, including primitives and protocol design.
- Practical experience implementing or auditing cryptographic systems.
