Discipline: GDS Enablement Services – Growth & Innovation Role title: Quantum – Senior Associate   Position Summary: The Quantum Senior Associate will play a hands-on delivery role across Quantum Technology initiatives, with stronger ownership for solution design, technical execution, stakeholder communication and delivery quality than an Associate role. The role requires practical experience in quantum-safe security and/or quantum computing, with the ability to translate complex technical concepts into clear business and delivery outcomes. The role is expected to have a primary focus on quantum safety, including post-quantum cryptography readiness, and a secondary focus on quantum computing use cases such as optimization, machine learning and simulation.   Key responsibilities

Support the development of quantum safety and quantum computing solutions, prototypes and demonstrations. Contribute to post-quantum cryptography readiness assessments, including data gathering, analysis and documentation. Develop and evaluate quantum algorithms and workflows for selected optimization, machine learning and simulation use cases. Build and maintain software tools, accelerators and proof-of-concept assets using established engineering practices. Prepare technical documentation, assessment reports and presentation materials for internal and external stakeholders. Collaborate with cross-functional teams including cybersecurity, AI/ML, platform engineering and product teams. Participate in testing, validation and benchmarking activities to assess solution performance and applicability. Stay current on developments in quantum computing, post-quantum cryptography and related emerging technologies.

Support quantum risk assessments and identify areas that may require future cryptographic modernization. Assist in prototyping and benchmarking post-quantum cryptography algorithms within applications and services. Contribute to analysis of quantum-safe and hybrid cryptographic approaches and document findings. Support development of crypto-inventory and discovery capabilities to identify legacy cryptography dependencies. Execute testing of hybrid key exchange mechanisms and document performance observations. Assist with implementation and validation of crypto-agility patterns, certificate updates and key management enhancements. Contribute to creation and maintenance of migration guides, standards documentation and operational runbooks.

Develop and evaluate quantum algorithms using industry-standard quantum development platforms. Support experimentation and testing to assess the practicality of quantum use cases. Build proof-of-concept solutions for optimization, simulation and emerging Quantum + AI use cases. Perform basic resource estimation and analysis of quantum circuits and algorithm performance. Compare classical and quantum approaches and document observations and recommendations. Maintain reproducible experimentation environments using Python, Jupyter notebooks, containers and source control tools.

Foundational understanding of quantum computing concepts, including qubits, gates, quantum circuits and current hardware limitations. •Basic understanding of post-quantum cryptography concepts, key encapsulation mechanisms, digital signatures and emerging standards. Familiarity with cryptographic concepts such as public-key cryptography, certificates and secure communication protocols. Experience
