IonQ is hiring a Staff Cryptography Engineer in Geneva for ID Quantique, its quantum-safe communications business. The role focuses on software for post-quantum cryptography hardware acceleration in HSM and network appliances: reference and bit-accurate models of ML-KEM, ML-DSA and SLH-DSA/LMS, constant-time implementations, and NIST ACVP/CAVP test-vector tooling. It asks for a master’s degree, five or more years implementing cryptographic or security-critical software in C/C++ or Rust, and English fluency; French or German is an advantage. Work is onsite.
