Rust Software Engineer

Rust Software Engineer – Cryptography & Blockchain

We're seeking a skilled Rust developer to join a specialized team. This role involves designing and implementing secure software components using Rust, with a strong emphasis on performance, reliability, and cutting-edge cryptographic techniques.

What You'll Do

• Build and maintain cryptographic libraries and protocols using Rust.
• Develop secure and efficient code for systems involving encryption, digital signatures, zero-knowledge proofs, and secure multi-party computation.
• Optimize software for performance and scalability in constrained environments.
• Collaborate with engineers and researchers to integrate cryptographic primitives into broader platforms such as privacy-preserving applications and secure communication tools.
• Conduct code reviews, write unit tests, and uphold secure coding standards.
• Troubleshoot complex issues related to cryptographic logic and system behavior.
• Stay informed on the latest developments in cryptography and the Rust ecosystem.
• Contribute to system architecture and API documentation.
• Work cross-functionally to ensure seamless deployment of cryptographic components.

What You Bring

• A degree in Computer Science, Mathematics, Cryptography, or equivalent experience.
• 3+ years of professional software development, including 2+ years of Rust programming.
• Deep understanding of cryptographic principles: symmetric/asymmetric encryption, hash functions, digital signatures, zero-knowledge proofs.
• Strong systems programming skills: memory management, concurrency, and low-level optimization.
• Experience with cryptographic libraries such as OpenSSL, libsodium, or Rust-native options like ring or rust-crypto.
• Familiarity with secure development practices and threat mitigation.
• Exposure to blockchain technologies or distributed systems is a plus.
• Excellent problem-solving abilities and attention to detail.
• Strong communication and collaboration skills.
