About IonQ:
IonQ, Inc. [NYSE: IONQ] is the world’s leading quantum platform and merchant supplier - delivering integrated quantum solutions across computing, networking, sensing, and security. IonQ’s newest generation of quantum computers, the IonQ Tempo, is the latest in a line of cutting-edge systems that have been helping customers and partners including Amazon Web Services, and AstraZeneca achieve 20x performance results and accelerate innovation in drug discovery, materials science, financial modeling, logistics, cybersecurity, and defense. In 2025, the company achieved 99.99% two-qubit gate fidelity, setting a world record in quantum computing performance.
Headquartered in College Park, Maryland, IonQ has operations in California, Colorado, Massachusetts, Tennessee, Washington, Italy, South Korea, Sweden, Switzerland, Canada, and the United Kingdom. Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before.
We are looking for a 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. 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:
- Develop novel control schemes for fast, robust, and low-excitation ion transport.
- Design and optimize control waveforms to perform operations such as ion loading, transport, qubit routing, and gate operations.
- Simulate the physics of ion chains in the RF Paul traps at the heart of our systems.
- Collaborate with interdisciplinary teams comprising physicists, engineers, and researchers to integrate ion transport into larger experimental setups or commercial products. Effectively communicate technical concepts, design rationale, and experimental results to stakeholders through reports, presentations, and documentation.
- Collaborate with quantum architects to co-design transport operations, novel trap designs, and quantum error correction (QEC) primitives for future commercial systems.
You’d be a good fit with:
- PhD in atomic physics, quantum information, or a related field with experience operating or supporting experimental hardware or equivalent experience.
- Background in designing or operating surface electrode RF Paul traps.
- Proficiency in numerical physics simulations.
- Strong communication and collaboration skills
You’d be a great fit with: (Desired experiences/skills 5-10 bullets)
- Strong understanding of fundamental principles governing ion trap operation, including electrostatics, quantum mechanics, and ion dynamics.
- Proficiency with scientific programming and numerical optimization.
- 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
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.
US Non-Technical Jobs. Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum. 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.
