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 Ready to Apply? Send us your resume and a brief introduction explaining why you're interested in this role and what makes you a great fit. #J-18808-Ljbffr
