Cryptography Engineer – Unifacator Security

Enigma Genetics; United States; Remote; USD 130,000 - 160,000; Full time

Job summary

Enigma Genetics seeks a security-focused cryptography engineer to build the platform’s cryptographic layer, including signing, key management, privacy-preserving validation, and post-quantum readiness. This is a fully remote, full-time role in the United States.

You will implement digital-signature workflows evolving from ECDSA to PQC, design key rotation with Shamir schemes, create zero-knowledge components, and perform threat modeling and penetration testing to harden protocols.

Qualifications

• 5+ years of applied cryptography experience.
• Proficiency in C++ or Rust.
• Knowledge of Kyber, Dilithium, and biometric key binding.
• Strong track record implementing secure protocols.

Responsibilities

• Implement digital-signature workflows that can move from ECDSA toward post-quantum cryptography.
• Design and deploy key rotation and recovery mechanisms, including Shamir Secret Sharing.
• Develop zero-knowledge proof components for validating attributes while limiting information disclosure.
• Conduct penetration testing and threat modeling to identify weaknesses in protocols and integrations.
• Help secure biometric-gated encryption and the consent and key-exchange flows it supports.

Job description

Role overview

Build the cryptographic security layer for a platform that uses biometric access to protect consent records and key exchanges. The work spans signing, key management, privacy-preserving validation, and security testing, with an emphasis on robust protocol implementation and a transition toward post-quantum cryptography.

Responsibilities

• Implement digital-signature workflows that can move from ECDSA toward post-quantum cryptography.
• Design and deploy key rotation and recovery mechanisms, including approaches based on Shamir Secret Sharing.
• Develop zero-knowledge proof components for validating attributes while limiting information disclosure.
• Conduct penetration testing and threat modeling to identify weaknesses in protocols and integrations.
• Help secure biometric-gated encryption and the consent and key-exchange flows it supports.

Requirements

• At least 5 years of applied cryptography experience.
• Proficiency in C++ or Rust.
• Knowledge of Kyber, Dilithium, and biometric key binding.
• A strong track record implementing secure protocols.

Benefits and work setup

• Full-time remote role.
• Compensation listed as either $130,000-$160,000 or $90,000 plus 0.75%-1.5% equity.
