Senior Quantum Scientist

Role Overview

IonQ is hiring a Senior Quantum Scientist for a full‑time role based in Boulder, Colorado. The position falls within IonQ’s Security hiring group.

Office: Boulder, CO with a hybrid model allowing a few days of remote work per week.

As a Quantum Scientist, you will

• Prototype and characterize coherent control and cooling schemes for trapped‑ion qubits using laser and microwave fields.
• Calibrate and benchmark quantum systems, focusing on achieving ultra‑low gate errors and optimizing performance across device modules.
• Validate emerging trap technologies, including integrated electronics and photonics for large‑scale architectures.
• Analyze experimental data, debug complex hardware/software interactions, and ensure reliability of qubit operations.
• Present results internally and externally, representing IonQ at conferences and in collaborations.

We look for a candidate with:

• PhD in physics or a related discipline with strong background in atomic or qubit‑related physics; postdoc or industry experience is a plus.
• Proven expertise in experimental AMO physics or quantum computing, with a preference for trapped‑ion experience.
• Strong collaborative skills and ability to work independently in a fast‑moving team.
• Experience with spectroscopic or simulation of multi‑level systems, characterization of control hardware, gate‑fidelity benchmarking, or running algorithms on hardware.
• Strong proficiency in programming and data analysis.
• A track record of scientific communication through publications, talks, and conferences.

The approximate base salary range is $126,887–$166,127. Total compensation includes base, bonus, equity, and benefits such as comprehensive medical, dental, and vision plans; 401(k) matching; unlimited PTO and paid holidays; parental/adoption leave; legal insurance; and a home‑technology stipend.
