Cryptography Engineer

Design and implement cryptographic primitives, with a focus on performance across processor architectures and resistance to side-channel attacks. The work includes contributing to post-quantum research, reviewing security-critical code, and documenting technical findings.

• Implement cryptographic algorithms in Rust.
• Optimize implementations for CPU architectures such as x86 and ARM.
• Develop constant-time code and account for side-channel attack risks.
• Contribute to post-quantum cryptography research and implementation.
• Review code and participate in security audits of cryptographic systems.
• Prepare technical documentation and contribute to research papers.

• Strong foundations in cryptography and mathematics.
• At least three years of systems programming experience in Rust, C, or C++.
• Deep understanding of symmetric and asymmetric cryptography.
• Familiarity with side-channel attacks and countermeasures.
• Experience with processor-specific optimization, such as SIMD or intrinsics.

• Experience with post-quantum algorithms such as ML-DSA or ML-KEM.
• Contributions to open-source cryptography projects or published security research.
• Familiarity with formal verification tools or zero-knowledge proof systems.
