Senior Quantum Engineer

Our partner, a Fortune 500 company, runs an Emerging Tech lab that builds rapid proofs of concept to test how emerging technologies — AI, Blockchain, IoT, Robotics, VR/AR — can be applied to real business use cases. We're looking for Senior Quantum Engineers to bring quantum computing competency to their team. You'll design and prototype quantum and hybrid quantum-classical solutions, build AI assets (e.g., plugins) that drive the firm-wide AI strategy, and contribute to ongoing AI and quantum R&D initiatives. This is a long-term, fully remote contract position (likely extension) with required US working hours overlap (2-6 PM CET). Responsibilities - Quantum algorithms: design, implement, and benchmark quantum algorithms (Shor's, Grover's, variational quantum algorithms) for business use cases. - Quantum optimization: formulate optimization problems as QUBOs and solve them with D-Wave's quantum annealing (Leap/Ocean). - Gate-based development: build and run quantum circuits using IBM Qiskit on platforms such as IBM Q, Rigetti, or Google Quantum. - Prototyping & PoCs: rapidly turn hypotheses into prototypes, demos, and learnings that teams and clients use to decide where to invest in emerging tech. - AI assets & R&D: develop AI assets (e.g., plugins) and contribute to R&D initiatives, including quantum NLP and quantum cryptography use cases. - Performance: write efficient classical code (Python, C++, Julia) with a focus on optimization and computational efficiency. Work Conditions - Type: Full-time, Long-term contract - Start Date: ASAP - Location: Remote - US Time Zone Overlap: Required (2 PM - 6 PM CET, ideally until 7 PM CET) - Contract with EU LLC
