CryptoNext Security

Software Engineer

• Design and implement efficient C code for post-quantum cryptographic algorithms selected or recommended by NIST or EU agencies.
• Port and optimize the CryptoNext Quantum Safe Library (C-QSL) across multiple platforms and architectures.
• Adapt implementations for constrained and embedded environments such as IoT, Cortex-M, and embedded Linux.
• Define and run functional, performance, and security testing and validation strategies across target platforms.
• Support CSPN, Common Criteria, and FIPS security certification processes for ported implementations.
• Document work through technical reports and, where relevant, scientific papers.
• Collaborate with R&D and cross-functional teams to solve complex technical challenges.
• Work with C and Assembly implementations targeting Linux, Windows, iOS, Android, x86, Arm, RISC-V, and FPGA-based hardware accelerators.
• Potentially work on side-channel countermeasures and integration with TLS, IPsec, PKCS#11, and X.509 in post-quantum or hybrid mode.
