Cryptography Auditor

About the Role

Requirements

• Strong understanding of modern cryptographic primitives including encryption, signatures, key exchange, hash functions, MACs, and RNGs
• Working knowledge of classical and quantum-resistant primitives
• Proven experience auditing or developing cryptographic code in Rust, Go, C/C++, TypeScript or Python
• Experience with static and dynamic analysis, fuzzing, and adversarial testing for cryptographic components
• Ability to identify and validate vulnerabilities through proofs of concept and threat modeling
• Familiarity with zero-knowledge systems and domain-specific ZK languages (e.g., Groth16, Plonk, Halo2, zkSTARKs, zkVMs, Circom, Noir, Leo, Cairo, ZoKrates)
• Understanding of secure multi-party computation and threshold cryptography including DKG and threshold signatures
• Knowledge of post-quantum schemes (e.g., Kyber, Dilithium, Falcon, SPHINCS+) and PQC-based constructions
• Familiarity with relevant standards and specifications (NIST FIPS, ISO/IEC 14888, 15946, 11770)
• Adherence to structured audit workflows and strong reporting skills

Responsibilities

• Perform in-depth security audits of cryptographic protocols
• Identify and mitigate cryptographic vulnerabilities
• Deliver comprehensive security reports with remediation guidance
• Collaborate with client development teams to support remediation
• Contribute to development and improvement of internal audit tools
• Engage with the security and cryptography community
