Simulation Physicist - Ion Transport and Waveform Design

Simulation Physicist – Ion Transport and Waveform Design

IonQ is developing the world's most powerful full-stack quantum computer based on trapped‑ion technology. We are pushing past the limits of classical physics and current supercomputing technology to unlock a new era of computing. Quantum computing has the potential to impact every area of human society for the better. IonQ’s computers will soon redefine industries like medicine, materials science, finance, artificial intelligence, machine learning, cryptography, and more.

IonQ is at the forefront of this technological revolution.

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.

• 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.

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.

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: Onsite in Boulder, CO or Oxford, UK.
Travel: Up to 10% (domestic and international).

The approximate base salary range for this position is $110,336 - $144,459. The total compensation package includes base, bonus, and equity.

Benefits include comprehensive medical, dental, and vision plans, 401(k) matching, unlimited PTO and paid holidays, parental/adoption leave, legal insurance, home internet stipend, and pet insurance.
