About Quantum Brilliance

Quantum Brilliance is the world leader in room-temperature quantum computing using synthetic diamonds. Our vision is to make quantum computing available as an everyday technology, from data centres to remote and mobile systems like autonomous robots and satellites. We are developing quantum accelerators with more compute power than a classical supercomputer but in a form factor smaller than a lunchbox.

Founded in 2019 by leaders in diamond quantum science from the Australian National University, we are a full-stack quantum computing company. An Australia-German company, our HQs are in Canberra and Stuttgart, with additional locations across eastern Australia and southern Germany. We are working with global technology leaders to develop quantum computing applications, integrate quantum with high-performance computing, solve materials science challenges and develop ultra-precise semiconductor manufacturing and quantum control techniques. We are backed by leading venture capital funds and major research and technology institutes.

What we do in our Stuttgart Lab

In Stuttgart, we are working to bring all the pieces together to build the Integrated Quantum Chip. This new chip is based on diamond and contains the core components for harnessing the power of quantum technologies. You will play a crucial role in developing and implementing device modelling solutions, from fundamental physical models to compact models suitable for circuit simulations, contributing to the overall design and optimization of our prototype integrated quantum devices and products.

Your tasks

Responsibilities include:

• Develop physical models for the electrical, optical, and thermal behavior of our diamond-based integrated quantum devices and perform advanced device simulations using FEM tools (e.g., COMSOL) and TCAD software.
• Validate device models against experimental data and extract key device parameters.
• Design and implement compact models suitable for circuit-level simulations (e.g., in SPICE).
• Perform advanced device simulations using Finite Element Method (FEM) tools (e.g., COMSOL) and Technology Computer-Aided Design (TCAD) software.
• Develop and execute simulation plans to optimize device performance and reliability.
• Collaborate closely with experimental teams to validate device models against measured data.
• Analyze simulation results, identify key performance drivers, and provide insights for device design improvements.
• Strengthen and potentially lead our efforts in developing a comprehensive device modeling solution, encompassing measurement data analysis, model development, and verification.
• Document modeling methodologies, simulation results, and model validation reports.
• Contribute to intellectual property generation through invention disclosures and patent applications.

About you

• You hold a PhD degree in Electrical Engineering, Physics, Materials Science, or a related discipline with a strong focus on semiconductor devices.
• You have a strong theoretical understanding of semiconductor physics, device operation, and transport phenomena.
• You have previous experience in semiconductor device modeling and simulation. Knowledge and expertise on wide bandgap materials such as diamond are a plus.
• You have hands-on experience with FEM-based simulation tools, particularly COMSOL Multiphysics, for semiconductor device modelling, and experience in developing and implementing compact models for circuit simulation using SPICE or similar tools.
• You have demonstrated the ability to validate device models against experimental data and extract key device parameters.
• You can work independently and as part of a team in a fast-paced, high-tech environment. You are self-motivated, well-organized, and meticulous in following procedures.
• You are eager to learn and adapt quickly to new challenges.
• You speak English; German is a plus.

What we offer

• Exciting work at the intersection of research and application, with diverse tasks in a dynamic, team-oriented environment.
• On-site role within our Stuttgart Lab.
• Space for your ideas – be creative and make a real impact!
