Position Summary
The Quantum Associate will work on Quantum Technology initiatives. This role requires background, knowledge, and practical experience with the usability and impact of quantum technologies. 60‐70% focus on quantum safety and 30% focus on quantum compute.
Essential Responsibilities of the Job
* Build & Commercialize: Lead and support development, demos, and presentations of solutions in both quantum cybersecurity and quantum computing domains.
* Quantum Safety: Contribute to the organization's PQC (post‐quantum cryptography) readiness, including risk assessments, migration planning, and crypto‐agility improvements.
* Quantum Compute: Develop and evaluate quantum algorithms and workflows for optimization, machine learning, and simulation use cases.
* Software Development & Implementation: Build software kits and tools, design and implement architectures, benchmark performance, and employ best practices in software engineering.
* Thought Leadership: Produce clear leadership and sector presentations, assessment reports, standards, and executive‐level documents.
* Teaming: Collaborate with cross‐functional teams including security engineering, ML/AI groups, platform teams, and product stakeholders.
Quantum Specialist Responsibilities
Quantum Cyber
* Assess quantum‐related risks (e.g., harvest‐now‐decrypt‐later exposure) and contribute to mitigation roadmaps.
* Prototype and benchmark PQC algorithms (e.g., ML‐KEM/Kyber, ML‐DSA/Dilithium) within services and applications.
* Maintain an index of how the current and upcoming proposed algorithms fare fully PQ secure and hybrid versions of the same against operational impacts to recommend appropriate migration roadmaps.
* Support development of crypto‐inventory tools to detect legacy cryptography dependencies.
* Implement and test hybrid key exchange schemes and measure performance impacts (latency, throughput, resource usage).
* Assist with design and validation of crypto‐agility patterns, certificate lifecycle updates, and key management transitions.
* Contribute to internal PQC migration guides, standards, and runbooks.
Quantum Compute & Algorithms
* Develop accelerators using NISQ‐appropriate quantum algorithms (VQE, QAOA, QML) and industry SDKs for use cases.
* Run extensive testing and validation exercises to estimate viability, usage and support roadmapping of quantum utility for use cases.
* Build end‐to‐end prototypes for domain‐specific use cases such as optimization, simulations, modeling of Quantum as well as next frontier of Quantum & AI/ML tech.
* Perform resource estimation (qubit count, gate depth, circuit complexity) and evaluate classical‐quantum tradeoffs.
* Maintain reproducible experimentation pipelines using Python, Jupyter, containerization, and CI workflows.
Knowledge and Skills Requirements
* Foundational understanding of quantum computing principles, qubits, gates, NISQ constraints, and error mitigation.
* Working knowledge of post‐quantum cryptography, including KEMs, signature schemes, and cryptographic standards.
* Familiarity with PKI, TLS 1.3, certificate management, and key exchange mechanisms.
* Proficiency with one or more quantum SDKs: Qiskit, Cirq, PennyLane, AWS Braket, Azure Quantum/QDK.
* Strong Python programming capabilities, including numerical libraries (NumPy, SciPy, pandas).
* Understanding of classical optimization, linear algebra, and probabilistic reasoning.
* Experience with version control (Git), containers (Docker), and CI/CD workflows. Languages: Python, C++, Rust, or equivalent.
* Strong written and verbal communication skills, with the ability to distill complex concepts for different audiences.
* Analytical thinking and a structured, hypothesis‐driven approach to problem solving.
Education & Experience
* Bachelors or Masters in Physics, Computer Science, Cybersecurity, EE, Applied Math, or related field; or equivalent hands‐on experience.
* 2‐3+ years of hands‐on experience in at least one of the following areas: post‐quantum cryptographic implementations, applied cryptography or security engineering, quantum algorithm development.
* Experience in quantum technologies, cryptography, or related computational fields is a plus.
* Publications, preprints, hackathon projects, or open‐source contributions in quantum or applied security are highly desirable but not required.
* Familiarity with cybersecurity fundamentals (public‐key crypto, KEMs/signatures, TLS, PKI concepts).
* Understanding of post‐quantum cryptography basics and current standardization landscape.
* Experience with at least one quantum SDK (e.g., Qiskit, PennyLane, or Azure Quantum QDK).
* Ability to design small experiments, analyze results, and write clear technical documentation.
