Zero Knowledge / Cryptography Audito at Nethermind

About the Company

Nethermind is a leading blockchain research and engineering company building high-performance infrastructure, advanced security tooling, and cryptographic systems across the Ethereum ecosystem and beyond. The team partners with protocol developers, Layer 2 solutions, and zero-knowledge (ZK) projects to design and secure next-generation decentralized technologies.

Role Overview

We are seeking a Zero Knowledge / Cryptography Auditor to join our growing security team. In this role, you will be responsible for assessing the correctness, security, and robustness of cryptographic protocols and ZK systems. You will work across Ethereum and emerging ecosystems, contributing to the security of cutting-edge decentralized applications.

Key Responsibilities

• Conduct in-depth security audits of cryptographic protocols, primitives, and zero-knowledge systems
• Evaluate correctness, soundness, and potential vulnerabilities in zkDSL circuits and zkVM programs
• Review production-level code within Ethereum and ZK ecosystems to identify and mitigate risks
• Collaborate with internal teams to enhance blockchain security tools and frameworks
• Design and develop new tools for auditing cryptographic and ZK systems
• Stay current with evolving ZK technologies, proof systems, and emerging threat vectors
• Communicate audit findings clearly to clients and provide actionable remediation recommendations
• Contribute to internal research, documentation, and knowledge-sharing initiatives

Requirements

• Minimum of 1 year experience in cryptography, ZK systems, or related security auditing
• Bachelor’s or Master’s degree in Computer Science, Cybersecurity, Mathematics, or a related field
• Strong foundation in cryptography, including both theory and practical implementation
• Proficiency in Rust (experience auditing Rust codebases is highly desirable)
• Hands-on experience with at least one ZK proof system (e.g., Groth16, PLONK, Halo2, Bulletproofs)
• Familiarity with zkDSL tools (e.g., Circom, Noir, Cairo, Halo2)
• Understanding of zkVM architectures and proof pipelines
• Ability to identify cryptographic vulnerabilities and security flaws
• Strong analytical, debugging, and communication skills

Nice to Have

• Background in traditional cybersecurity prior to blockchain
• Experience with advanced cryptographic concepts (e.g., threshold signatures, FHE, anonymous credentials)
• Familiarity with ZK rollups or Layer 2 ecosystems (e.g., Aztec)
• Published audit reports, technical blogs, or security research
• Experience in client-facing or consulting roles

What We Offer

• Fully remote, flexible work environment
• Opportunity to work with a global, diverse team
• Exposure to cutting-edge blockchain and cryptography projects
• Continuous learning, mentorship, and career development opportunities
• Access to industry events and conferences
• Collaborative and innovation-driven culture
