- 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
