Employer Type
This role seeks a Simulation Engineer to model, simulate, and optimize trapped ion systems for quantum computers developed by eleQtron. The engineer will execute high-accuracy simulations of complex fields (electrostatic, RF, magnetic, microwave) and ion transport dynamics using tools like COMSOL Multiphysics. They will collaborate with other engineers to translate physical designs into validated simulation models, directly guiding device development and scaling towards fault-tolerant quantum computing.
Key Responsibilities
Model, simulate, and optimize ion trap systems using high-accuracy simulations of electrostatic, RF, magnetic, and microwave fields.
Simulate single- and multi-ion dynamics, analyzing ion shuttling protocols and evaluating ion stability within time-dependent potentials.
Develop parameterized COMSOL models to explore design trade-offs, extract physical quantities, and validate simulation results against experimental data.
Collaborate with experimental and theoretical teams to refine trap designs and provide actionable recommendations based on simulation outcomes.
Required Skills
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.
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).
Ability to critically assess scientific literature, define validation strategies, and report R&D results in a structured and traceable manner.
Nice-to-have Skills
Experience in quantum information, trapped ions, or atomic physics.
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.
Familiarity with version control systems (e.g. Git).
