• Design, implement, and analyze cryptographic protocols using non-standard lattice assumptions, ensuring they meet the highest security standards.
• Lead the integration of cryptographic primitives into our Quantum Framework, optimizing for security and efficiency.
• Prototype, test, and deploy lattice-based cryptographic solutions in operational quantum environments.
• Collaborate with academia, cryptographers, and auditors to validate and refine cutting-edge cryptographic methods.
• Implement cryptography specifications into secure, production-level code within the Quantum Framework.
• Provide expert support for the integration of quantum-resistant protocols across our technology stack.
• Document research findings, code, and APIs thoroughly, contributing to the academic and practical discourse on quantum-resistant cryptography.

• PhD in Quantum Cryptography, Quantum Information Theory, or a closely related field.
• 5 years post-doctoral experience in a competitive quantum cryptography/information research group.
• Deep expertise in lattice-based cryptography, advanced encryption, and signature schemes.
• Working knowledge of semi-definite programming and numerical optimization techniques.
• Experience with fine-grained cryptography and impossibility results.
• Experience in designing and analyzing homomorphic, attribute-based, functional encryption, and signature schemes.
• Published research in cryptography.
• In-depth knowledge of TCP/IP.
• Proficiency in C++ and ASM programming.
• Advanced technical knowledge in application and hardware security.

• Advanced technical knowledge in Electromagnetism and quantum algorithms/materials.
• Experience with quantum optics and laboratory apparatus, including SPDC entanglement sources, single-photon detectors, and Bell-state measurement systems.
• Expertise in low and room temperature qubit measurements, including MKS systems.
• Proficiency in cryogenics, lithography, and fiber optics.
• Experience with computer-aided design (CAD) for advanced quantum systems.
• Familiarity with NSTISSAM TEMPEST/1-92 and CNSSAM TEMPEST/01-02 specifications.
• Effectively communicate technical and non-technical information verbally and in writing to diverse audiences.

This role offers a unique opportunity to contribute to cutting-edge advancements in quantum cryptography and secure communications technology for land, subsea, and space operations using our internal assets.
