Who we are 

At CryptoNext Security, we are shaping the future of cybersecurity with post-quantum cryptography solutions. As a software vendors, our mission is to protect the critical data of the world’s largest enterprises and governments against emerging threats from quantum computers. Recognized as leaders in our field, we collaborate with organizations like banks, security institutions, and government entities to deploy CryptoNext’s solutions through cutting-edge technology projects. If you want to be at the heart of innovation and contribute to making the world safer, CryptoNext is the perfect place to enhance your skills. 

On a daily basis, you will
  • Design and implement post-quantum cryptographic algorithms, aligning with NIST or EU standards, and contribute to the CryptoNext Quantum Safe Library using languages such as C, Rust, and Assembler.
  • Execute and mitigate side-channel attacks, optimizing cryptographic implementations for IoT and embedded environments.
  • Develop and integrate post-quantum or hybrid cryptographic protocols (e.g., TLS, IPSEC, PKCS#11, X.509) and objects with various cryptographic tools (e.g., OpenSSL, BouncyCastle).
  • Collaborate with team members to create formal security proofs, and work on network defenses such as DPI probes.
  • Integrate CryptoNext software solutions with various technologies, including VPN, HSM, PKI, digital signatures, and blockchain.
  • Conduct comprehensive testing and validation to ensure the robustness and resilience of our cryptographic solutions.

CryptoNext software solutions are produced with several computer languages: mainly C, and also Java, RUST, Assembler and for various operating systems (Linux, Windows, iOS, Android…) and processors (Intel, Arm, PowerPC, …).

Requirements

The skills you will demonstrate
  • Expertise in Cryptography: Strong background in public-key cryptography, symmetric-key cryptography, hash functions, and experience with frameworks like OpenSSL.
  • Programming Proficiency: High competence in C or Java, with additional knowledge in Rust and Assembler.
  • Problem-Solving and Innovation: Ability to approach challenges creatively and critically, pushing the boundaries of cryptographic solutions.
  • Collaborative and Proactive: Capacity to work both independently and collaboratively, with a proactive and rigorous approach.
  • Language Skills: Proficiency in French and English, with strong communication skills in both oral and written formats.
The team you’ll be joining

You will join our high-level R&D team, made of cryptography experts dedicated to post-quantum research and development. This team works closely with cross-functional groups to ensure our solutions are cutting-edge, secure, and effective. This is the bigger team within the company.

Benefits

What's in it for you at CryptoNext
