Job Summary
In this role, you will model and simulate high-precision ion trap systems using COMSOL Multiphysics, analyze dynamics, and optimize trapping potentials for advanced quantum computing.
Job Technologies
Your role in the team
- As a Simulation Engineer (m/f/d), you will model, simulate, and optimize ion trap systems.
- The role involves high-accuracy simulations of electrostatic, RF, magnetic, and microwave fields, as well as ion shuttling dynamics and trapping potentials, using COMSOL Multiphysics.
- You will collaborate closely with interdisciplinary quantum engineers to translate physical designs into validated simulation models, guiding device development and workflow integration that support the company's scaling strategies toward fault-tolerant quantum computing.
- Model static and time-dependent electrostatic potentials of segmented ion traps.
- Simulate RF (Paul trap) fields and derive effective (pseudopotential) trapping potentials.
- Compute magnetic field distributions, including gradients and field stability.
- Simulate microwave field distributions for qubit control and coupling.
- Simulate single- and multi-ion dynamics in time-dependent potentials.
- Analyze ion shuttling protocols, including transport speed, motional excitation, and heating.
- Evaluate stability regions, secular frequencies, and micromotion effects.
- Develop parameterized COMSOL models to explore design trade-offs.
- Extract physical quantities (trap depths, frequencies, field homogeneity).
- Validate simulation results against analytical models and experimental data.
- Automate simulation workflows where appropriate (e.g., via COMSOL LiveLink).
- Interface with experimental and theoretical teams to refine trap designs.
- Clearly document simulation assumptions, methods, and results.
- Provide actionable design recommendations based on simulation outcomes.

Qualifications
- MSc or PhD in Physics, Electrical Engineering, or a related field with a strong understanding of ion trapping physics (Paul traps, pseudopotential theory).
- Strong foundation in classical electromagnetism and classical mechanics.
- Vertrautheit mit zeitabhängigen Simulationen und Partikelverfolgung/-analyse.
- Ability to critically assess scientific literature and technical reports, define validation strategies, and report R&D results in a structured and traceable manner.
- Knowledge of heating mechanisms, motional decoherence, or noise sources.
- Exposure to experimental ion trap setups or hardware constraints.
- Practical understanding of microwave engineering or RF electronics.
Experience
- Experience simulating electrostatic, RF, magnetic, and microwave fields.
- Experience with numerical and FEM-based simulation tools, such as COMSOL Multiphysics (AC/DC and RF Modules preferred).
- Scripting experience (e.g., Python, MATLAB, or COMSOL LiveLink); version control (e.g., Git) is a plus.
- Experience in quantum information, trapped ions, or atomic physics.
