Cryptography Engineer

Join our team to design and implement high-performance cryptographic algorithms. You'll work on post-quantum cryptography, symmetric ciphers, and zero-knowledge systems.

About the Role

We're looking for an experienced Cryptography Engineer to help build the next generation of secure systems. You'll work alongside world-class researchers and engineers on open-source projects that are trusted by major technology companies.In this role, you'll design and implement cryptographic primitives, optimize performance across different architectures, and ensure our implementations are secure against side-channel attacks.

Responsibilities

• Design and implement cryptographic algorithms in Rust
• Optimize performance for different CPU architectures (x86, ARM)
• Develop constant-time implementations resistant to side-channel attacks
• Contribute to post-quantum cryptography research and implementation
• Review code and security audits of cryptographic systems
• Write technical documentation and contribute to research papers

Requirements

• Strong background in cryptography and mathematics
• 3+ years of experience with systems programming (Rust, C, or C++)
• Deep understanding of symmetric and asymmetric cryptography
• Familiarity with side-channel attacks and countermeasures
• Experience with CPU-specific optimizations (SIMD, intrinsics)

Nice to Have

• Experience with post-quantum cryptographic algorithms (ML-DSA, ML-KEM)
• Contributions to open-source cryptography projects
• Published research in cryptography or security
• Experience with formal verification tools
• Knowledge of zero-knowledge proof systems
