Job description

Your role and responsibilities

As a Quantum Algorithm Theorist, you will pursue fundamental research aimed at discovering and developing new quantum algorithms across a range of useful application areas. Specifically, you will:

• Design novel and efficient quantum algorithms for scientifically and practically meaningful problems, with a focus on implementations suited to fault‑tolerant quantum computers.
• Rigorously characterize quantum speed‑ups using tools from computational complexity theory and through careful comparison with state‑of‑the‑art classical methods.
• Collaborate with our compiler, error‑correction, and hardware research teams to refine and optimize algorithms for early fault‑tolerant quantum architectures.
• Disseminate your findings through publications in leading peer‑reviewed journals and presentations at premier scientific conferences.
• Contribute to the broader research community by engaging with academic collaborators and helping to shape the intellectual direction of quantum algorithms research.

Required technical and professional expertise

A Ph.D. (completed or near completion) in Physics, Computer Science, Mathematics, Engineering, or a closely related field.

• Demonstrated research experience in the design and analysis of quantum algorithms.
• A track record of independent theoretical research, evidenced by original contributions to the field.
• Solid foundation in quantum information theory, computational complexity, and linear algebra.
• Proficiency in at least one general‑purpose programming language.

Preferred technical and professional experience

• Strong publication record in high‑impact, peer‑reviewed journals and top‑tier conference proceedings.
• Experience serving on technical program committees or as a reviewer for reputable conferences and journals in quantum computing or theoretical computer science.
• Postdoctoral research experience or completion of a graduate program with substantial focus on quantum algorithms, quantum complexity theory, or related areas.
