Job description

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for aQuantum Computing/Cryptography Engineer based in United States.

This role offers the opportunity to help organizations prepare for the rapidly evolving security challenges created by quantum computing. You will research and implement quantum-resistant cryptographic solutions while helping modernize enterprise security architectures. The position combines advanced quantum computing knowledge with practical cryptography, cybersecurity, and systems engineering. You will assess existing environments, identify quantum-related risks, and develop migration strategies toward post-quantum standards. You will also contribute to crypto-agile architectures and integrations across PKI, identity, cloud, network, and application environments. Working alongside cybersecurity architects, engineers, researchers, and system owners, you will translate emerging quantum-security requirements into practical solutions and long-term modernization roadmaps.

Accountabilities

• Research, design, and evaluate quantum-resistant cryptographic solutions, including post-quantum cryptography (PQC) algorithms and emerging quantum-safe security standards.
• Assess enterprise systems, applications, protocols, and cryptographic implementations to identify vulnerabilities and risks associated with current and future quantum computing threats.
• Design and implement cryptographic modernization and migration strategies for transitioning from traditional public-key cryptography to quantum-resistant algorithms.
• Develop, prototype, test, optimize, and integrate cryptographic algorithms, libraries, APIs, and security components into enterprise applications and infrastructure.
• Evaluate and implement NIST-standardized post-quantum cryptographic algorithms, including appropriate key-establishment and digital-signature mechanisms.
• Conduct cryptographic testing, security analysis, performance benchmarking, and interoperability testing to validate implementations and identify potential weaknesses.
• Develop crypto-agility architectures that enable organizations to efficiently replace or update algorithms, protocols, certificates, and keys as security requirements evolve.
• Support the integration of quantum-safe cryptography with PKI, identity management, TLS, VPNs, cloud platforms, network security systems, applications, and data-protection technologies.
• Collaborate with cybersecurity architects, software engineers, researchers, and system owners to translate quantum-security requirements into practical technical solutions and implementation standards.
• Produce technical documentation, architecture guidance, migration roadmaps, cryptographic inventories, risk assessments, and recommendations supporting post-quantum readiness.
• Assess organizational cryptographic inventories and establish migration priorities based on risk, technical dependencies, and future quantum threats.
• Provide technical and policy guidance aligned with NIST post-quantum cryptography standards, including FIPS 203, FIPS 204, and FIPS 205.
• Communicate complex quantum-security risks and modernization recommendations effectively to both technical teams and non-technical leadership.
• Apply project-management and configuration-management practices appropriate to large-scale enterprise and government technology environments.

Requirements

• 10+ years of overall IT experience, including at least 5 years of experience focused on quantum computing and cryptography within a large enterprise or government environment.
• Bachelor's degree in Business Administration, Business Management, Cybersecurity, Computer Science, Information Systems, Information Assurance, Information Security, Information Resource Management, or a related field.
• A Master's degree in a related IT discipline may substitute for up to two years of required professional experience.
• Deep knowledge of quantum mechanics, quantum algorithms such as Shor's and Grover's algorithms, and quantum information theory.
• Hands-on expertise with quantum programming languages and frameworks such as Qiskit, Cirq, Quipper, and the Microsoft Quantum Development Kit.
• Strong understanding of cryptographic protocols and algorithms, including RSA and AES, as well as public-key infrastructure (PKI).
• Extensive knowledge of post-quantum cryptography, quantum-resistant algorithms, and cryptographic modernization strategies.
• Strong understanding of established cryptographic standards and frameworks, including NIST and ISO/IEC 19790.
• Proficiency in programming languages such as Python, C++, and Java for implementing, testing, and analyzing cryptographic algorithms.
• Experience with classical and quantum simulation tools.
• Demonstrated expertise developing or advising on quantum-resistant algorithm migration plans and PQC implementation strategies.
• Ability to assess enterprise cryptographic inventories and identify migration priorities.
• Strong cross-functional collaboration skills, including the ability to communicate sophisticated quantum-security risks and recommendations to non-technical stakeholders.
• Experience providing policy, architecture, or technical guidance related to cryptographic modernization and NIST PQC standards.
• Experience working in project-oriented environments with an understanding of configuration management and enterprise technology lifecycles.
• One or more of the following certifications: IAT III, IAM III, or IASAE III.

Benefits

• Competitive salary paid twice per month.
• Best-in-class medical coverage with 100% of medical premiums covered by the employer.
• Company-wide new business incentive programs.
• Contribution incentives for activities such as white papers, blog posts, and internal webinars.
• Three weeks of PTO from the start of employment.
• 11 paid holidays annually.
• 401(k) program with a 100% company match on the first 4% contributed.
• Monthly reimbursement for cell phone and home internet expenses.
• Paternity and maternity leave.
• Employer investment in training and professional certifications to strengthen and expand technical expertise.
• Opportunities to work on advanced quantum-security and cryptographic modernization initiatives with significant enterprise and government impact.
