About the Next Frontier:

Applied Innovation's Next Frontier focuses on emerging technologies, including Physical AI, Quantum Computing, and Next-Generation AI amongst others. This initiative translates advanced capabilities into measurable outcomes, helping clients and EY teams improve decision-making, strengthen resilience, and unlock new opportunities through technology-driven solutions.

About the Delivery Team:

EY advances innovation in Quantum by enabling regional quantum labs and supporting business-driven initiatives. The focus is on practical quantum technologies and frameworks that deliver measurable, enterprise-value level benefits.

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. There will be 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 safe 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.
