The Role

IonQ, Inc. [NYSE: IONQ] is the world's leading quantum company delivering solutions to solve the world's most complex problems. IonQ's newest generation quantum computers, IonQ Tempo and IonQ Forte Enterprise, are the latest in cutting-edge systems that have been helping customers and partners such as Amazon Web Services, AstraZeneca, and NVIDIA achieve 20x performance results. The company achieved 99.99% two-qubit gate fidelity, setting a world record in quantum computing performance in 2025.

The company is accelerating its technology roadmap and intends to deliver the world's most powerful quantum computers with 2 million qubits by 2030 to accelerate innovation in drug discovery, materials science, financial modeling, logistics, cybersecurity, and defense. IonQ's advancements in quantum networking position the company as a leader in building the quantum internet.

We are looking for a Staff Scientist, Materials Science to join the Computational Sciences team at IonQ. This is a newly formed group within Applications R&D, focused on general physics problems in condensed matter and high energy physics alongside combinatorial optimization.

You will bring dedicated condensed matter and high energy physics capability into the team, working on problems that today are delivered through a borrowed virtual team drawn from across the organisation.

The work sits at the meeting point of traditional classical simulation and fault‑tolerant quantum computing. You will bring judgement about where each approach earns its place, working independently against goals and helping shape how IonQ tackles real scientific problems as the company moves towards fault‑tolerant applications.

Responsibilities

• Lead condensed matter and high energy physics application projects, working independently against agreed goals.
• Connect physics problems to quantum computation, selecting appropriate fault-tolerant algorithms and mapping problems onto quantum-native formulations.
• Combine classical simulation and HPC workloads with quantum methods in integrated end-to-end workflows.
• Compare computed results against experimental data, including neutron scattering observables such as dynamical structure factors and spectral functions.
• Collaborate with other fault‑tolerant algorithms researchers and with the quantum chemistry and software engineering teams, and contribute to publications and external technical representation.

Requirements

• A doctorate in Physics, Chemistry, Materials Science or a related field, with postdoctoral or industry experience and a track record of carrying research forward independently.
• Deep expertise in condensed matter or high energy physics: magnetic systems, strongly correlated materials, superconductivity, spin dynamics, Fermi‑Hubbard models, lattice gauge theory or related areas.
• Experience with classical simulation methods and HPC workloads for these problems, ideally including packages such as QuantumATK, QuantumEspresso or VASP.
• Familiarity with fault‑tolerant quantum algorithms and their applications.
• Scientific programming in Python and C++ sufficient to integrate tools, run computations and maintain a code base in version control.
• Also valuable: hands‑on use of classical packages including QuantumATK, QuantumEspresso or VASP; the ability to design novel fault‑tolerant algorithms; a peer‑reviewed publication record; client or partner facing delivery experience; active participation in the fault‑tolerant quantum computing community through tools, metrics, talks, repositories or patents; and familiarity with agentic AI tooling such as OpenAI Codex or Anthropic Claude Code.

Also valuable, though not expected in every applicant: experience comparing simulation results against experimental data such as neutron scattering; hands‑on use of classical packages including QuantumATK, QuantumEspresso or VASP; the ability to design novel fault‑tolerant algorithms; a peer‑reviewed publication record; client or partner facing delivery experience; active participation in the fault‑tolerant quantum computing community through tools, metrics, talks, repositories or patents; and familiarity with agentic AI tooling such as OpenAI Codex or Anthropic Claude Code.

The total compensation package includes base, bonus, equity, and a range of benefit options found on our career site.

If this role has a commission structure, the compensation range below just reflects the base compensation range.

US Technical Jobs

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 "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.
