Post-Quantum Crypto Engineer — Remote Europe/Tallinn

SoftQuantus; United States; A distancia; USD 120.000 - 180.000; Jornada completa

Descripción de la vacante

SoftQuantus is seeking a cryptography engineer to own the post-quantum cryptography inside QuantumLock. You will extend signing and key management, harden the implementation, and ensure that public statements about cryptography are accurate.

You will work on ML-DSA, ML-KEM and SLH-DSA, design the missing encapsulation/decapsulation paths, build test vectors and negative tests, and prepare the code for independent review and validation.

Formación

• Hands-on experience implementing or integrating cryptographic primitives (≤140 chars).
• Working knowledge of lattice-based schemes and the NIST standards (≤140 chars).
• A careful habit of separating what is proven from what is assumed (≤140 chars).

Responsabilidades

• Implement and review the signing and key paths in QuantumLock
• Design the missing encapsulation and decapsulation path
• Build test vectors, fuzzing and negative tests for every cryptographic operation
• Prepare the implementation for independent review and validation
• Review every public statement about the cryptography before it is published
