Quantum Computing/Cryptography Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Quantum 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. 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
