Quantum Computing/Cryptography Engineer

Responsibilities

• Research, design, and evaluate quantum-resistant cryptographic solutions, including post-quantum cryptography (PQC) algorithms and emerging quantum-safe security standards.
• Assess existing enterprise systems, applications, protocols, and cryptographic implementations to identify vulnerabilities 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, and optimize cryptographic algorithms, libraries, APIs, and security components for integration into enterprise applications and infrastructure.
• Evaluate and implement NIST-standardized post-quantum cryptographic algorithms, including appropriate key establishment and digital signature mechanisms.
• Perform cryptographic testing, security analysis, performance benchmarking, and interoperability testing to validate algorithm implementations and identify potential weaknesses.
• Develop crypto-agility architectures that allow organizations to efficiently replace or update cryptographic 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 organizational post-quantum readiness and cryptographic modernization.

Requirements
