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
