pensacola, United States Stealth Communications Full time

Stealth Communications is seeking multiple postdoctoral researchers to advance our quantum-secure communication protocols and systems, at the intersection of post-quantum and quantum cryptography. This role combines theoretical research and practical experimentation on Stealth's quantum optical testbed (~5000 km: land + subsea assets), pushing the boundaries of cryptographic innovation.


This position requires security clearance and is based onsite in Pensacola, FL.


Qualifications:

  • Required: An active, transferable TS/SCI CI Poly U.S. government-issued security clearance prior to commencement.
  • 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 (e.g., ring, group, threshold).
  • Published research in cryptography.
  • In-depth knowledge of TCP/IP.
  • Proficiency in C++ and ASM programming.
  • Advanced technical knowledge in application and hardware security.
  • Strongly preferred:
  • -- 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.


Responsibilities:

  • Conduct advanced research in lattice-based cryptography, focusing on its potential to secure quantum communications and resist quantum attacks.
  • 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 Stealth’s 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 Stealth’s technology stack.
  • Document research findings, code, and APIs thoroughly, contributing to the academic and practical discourse on quantum-resistant cryptography.
  • Capable of independent work and collaboration within a diverse and multidisciplinary team, including scientists, engineers, business professionals, and ex-military personnel


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 Stealth's internal assets.


Salary starting at $250,000 + Sign-On Bonus of $250,000.
