Principal Numerical Physicist - 773

Quantinuum • Broomfield, CO

19d • $192,000 - $240,000

About The Position

We are seeking a Principal Numerical Physicist (or scientist) in our Broomfield, CO location to apply their skills to the development of our next generation large-scale quantum computers. The Ideal candidate will have a deep expertise with E&M modeling techniques. The candidate should also have a solid understanding of cryogenic systems, magnetics, CAD, thermal modeling, test design, and prototyping. This diverse set of topics will be used to create state-of-the-art models and designs for a commercial quantum computer that advances key performance metrics in qubit count, run-time, and circuit fidelity. This role will shape core architectural decisions for next-generation quantum computing systems, influencing performance, scalability, and manufacturability. You will operate across physics, hardware, and system architecture boundaries, using simulation and analysis to drive high-impact technical decisions in an evolving and ambiguous design space.
