Electromagnetic Simulation Engineer

Job Description

Job Title: Electromagnetic Simulation Engineer. Location: Boulder, Colorado, United States

Responsibilities:

• Lead the development of near-field electromagnetic simulation and optimization capabilities within the processor design team.
• Develop and refine 3D near-field electromagnetic models at RF frequencies using tools such as Ansys or COMSOL, including realistic materials, geometries, and boundary conditions.
• Model and analyze RF coupling and system-level behavior using LTspice or similar circuit simulation tools.
• Build automated simulation and optimization pipelines using Python, Julia, or MATLAB to improve design speed, accuracy, and repeatability.
• Translate theoretical electromagnetic models into scalable and manufacturable QPU architectures.
• Collaborate closely with quantum processor engineers, physicists, and fabrication teams to align simulations with design and manufacturing constraints.
• Establish and improve in-house electromagnetic modeling standards and best practices;
• Support the design and scaling of ion trap architectures, which are central to the company’s quantum systems.

Qualifications:

• At least 3 years of experience using Ansys, COMSOL, or equivalent FEM tools for time-varying electromagnetic simulation.
• Strong background in RF system modeling, including near-field analysis, parasitic coupling, and circuit simulation.
• Proficiency in Python, MATLAB, or Julia for automation, data analysis, and numerical optimization.
• MSc or PhD in Physics, Electrical Engineering, or a closely related field;
• Deep understanding of RF system modelling within complex multi-physics environments.

Benefits and Compensation:

• Competitive salary.
• IonQ stock options.
• Annual performance bonus.
• Generous annual leave.
• Flexible hybrid working model;
• Private medical and dental insurance for employees and their families.
• Career growth opportunities alongside industry-leading scientists and engineers.
