We are looking for a Simulation Physicist to join our Ion Transport and Waveform Design team. As a simulation physicist, you’ll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world’s best quantum computers to solve the world’s most complex problems.
In this role, you will study the physics of ion transport through numerical simulation. You will collaborate with experimental teams to validate simulation results and physics understanding, commercial teams to design transport waveforms used in our quantum computers, and quantum architects to inform the design of next-generation ion traps.
Responsibilities:
- Create, update, and maintain numerical simulation tools for ion transport in RF Paul traps.
- Validate simulation results in collaboration with experimental teams.
- Develop novel control schemes for fast, robust, and low-excitation ion transport.
- Deliver control voltage waveforms that implement the required operations for a trapped-ion quantum computer.
- Work with trap designers to incorporate novel transport techniques into future systems.
You’d be a good fit with:
- PhD in atomic physics, quantum information, or a related field.
- Experience in numerical simulation and optimization to inform experimental design.
- Strong proficiency in programming and data analysis.
- Strong communication and collaboration skills
You’d be a great fit with:
- Experience with transport or waveform design in surface-electrode RF Paul traps.
- Experience using a compiled programming language (Rust, C, C++, etc.) for scientific computing.
Location: This role will work onsite in Boulder, CO or Oxford, UK.
Travel: Up to 10% (domestic and international)

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
