Quantum Computing/Cryptography Engineer

As a Quantum Computing / Cryptography Engineer at Revolutional, you will lead the development and maintenance of an enterprise Cryptographic Inventory and Migration Plan in support of a Veterans Affairs (VA) program. You own the technical thread from cryptographic discovery through compliance validation and migration execution, identifying every cryptographic asset across VA systems, assessing compliance against federally mandated standards, and building the roadmap to modernize non-compliant and quantum-vulnerable cryptography, including migration to NIST-approved post-quantum cryptography (PQC) algorithms.

What you'll do

• Develop and deliver the enterprise Cryptographic Inventory and Migration Plan, serving as the authoritative record of all cryptographic assets and technologies deployed across VA systems, applications, and devices, with an initial version due within 120 calendar days of contract award and updated versions submitted semi-annually thereafter.
• Build and maintain a comprehensive cryptographic inventory detailing all algorithms, protocols, libraries, modules, hardware security modules (HSMs), key management systems, certificates, and related dependencies in use across the enterprise.
• Assess and document the compliance status of each cryptographic element against VA-approved and federally mandated standards, including FIPS 140-2/3.
• Identify all instances of non-compliant, legacy, or deprecated cryptographic algorithms and mechanisms, and evaluate the associated risk.
• Define detailed migration strategies for replacing or upgrading non-compliant or at-risk cryptographic elements, including actionable steps, technical requirements, and resource needs.
• Establish timelines and prioritization for migration activities, focusing first on assets and systems identified as highest risk or most critical to VA's mission and data protection objectives.
• Incorporate post-quantum cryptography (PQC) considerations by identifying systems and processes impacted by emerging quantum computing threats and specifying plans to migrate to NIST-approved PQC algorithms (FIPS 203, 204, 205) once available and appropriate, in accordance with VA guidance.
• Define roles and responsibilities for migration activities and coordinate execution with business and infrastructure owners across the enterprise.
• Establish and maintain processes for ongoing review and ad hoc updates to the cryptographic inventory as the environment evolves.
• Develop risk mitigation approaches for interim periods during which legacy or non-compliant cryptography must continue to be maintained.
• Develop metrics and reporting mechanisms to track migration progress and validate achievement of milestones.
• Advise program leadership and cross-functional, non-technical stakeholders on quantum computing risk, cryptographic modernization priorities, and PQC implementation strategy.
• Provide policy and guidance inputs to support cryptographic modernization efforts aligned with NIST PQC standards.
• Ensure cryptographic engineering and migration practices align with applicable compliance requirements and regulatory standards, including NIST and ISO/IEC 19790.

What you bring

• Minimum of 10 years of IT experience, of which at least 5 years are Quantum Computing and Cryptography experience at a large corporation or Government agency comparable in size and scope to GSA, IRS, DoD, or VA (a Master's degree in a related IT field may substitute for up to 2 years of required experience).
• Expertise in quantum mechanics, quantum algorithms (such as Shor's algorithm and Grover's algorithm), and quantum information theory.
• Expertise in quantum programming languages and frameworks such as Qiskit (IBM), Cirq (Google), Quipper, and Microsoft Quantum Development Kit.
• Expertise in cryptographic protocols (such as RSA and AES) and principles of public-key infrastructure (PKI).
• Expertise in post-quantum cryptography and quantum-resistant algorithms.
• Expertise in existing cryptographic standards and frameworks (such as NIST and ISO/IEC 19790).
• Proficiency in programming languages such as Python, C++, and Java for implementing and testing cryptographic algorithms.
• Expertise with classical and quantum simulation tools.
• Expertise advising on quantum-resistant algorithm migration plans and PQC implementation strategies, assessing organizational cryptographic inventory, and identifying migration priorities.
• Expertise collaborating with cross-functional teams to communicate quantum risk to non-technical leadership.
• Experience providing policy and guidance inputs for cryptographic modernization aligned with NIST PQC standards (FIPS 203, 204, 205).
• Expertise in project management or working in a project-oriented environment, with an understanding of how configuration management fits into the overall project lifecycle within a large corporation or Government agency comparable in size and scope to GSA, IRS, DoD, or VA.
• Bachelor's degree in Business Administration, Business Management, Cybersecurity, Computer Science, Information Systems, Information Assurance, Information Security, Information Resource Management, or related fields.
• Certification in one or more of the following: IAT Level III, IAM Level III, or IASAE Level III.

Nice to have

• Direct experience developing or contributing to a cryptographic inventory or migration plan for a federal agency.
• Familiarity with FedRAMP, FISMA, and RMF authorization processes related to cryptographic controls.
• Experience with HSM and key management system administration.
• Relevant certifications such as CISSP, GIAC GSE, or vendor-specific quantum computing credentials.

What we offer

• Salary of $160k-$180k depending on experience.
• Public Trust clearance required.
• Remote work with preference for local Washington, DC area.
• Full-time employment.
• Traditional and HSA-eligible medical insurance plans.
