Trainee for Cryogenic and Quantum Modelling (Fixed-Term)

At Bluefors, we’re enabling breakthroughs in quantum technology and scientific research through the world’s leading cryogenic

measurement systems and dilution refrigerators. As quantum computers scale up, understanding how the cryogenic environment and

control hardware affect qubits becomes ever more important. Our modelling work connects these worlds, from heat flow in a dilution

refrigerator to the behaviour of a single qubit.

We are looking for a Trainee for Cryogenic and Quantum Modelling to join our Quantum and Measurement Team. In this role, you’ll

help develop theoretical and numerical models that link the thermal, mechanical, and quantum aspects of our systems. Your work

will support customer projects, research and development, and Bluefors’ scientific publications.

We’re looking for someone with strong foundations in physics and numerical methods, real depth in at least one of our modelling

areas, and the curiosity to learn the others. You’ll work alongside experienced physicists and engineers who will support your

development throughout the year.

We offer you an interesting, challenging, and responsible position, supported by a highly skilled and growing organization. It’s

an excellent opportunity for professional growth in a dynamic, enthusiastic, and professional team where we work together and

support each other. Our working environment is multicultural and leaves room to grow, so you can use your full potential and keep

developing your skills.

• Help develop theoretical and numerical models that connect three areas:
• Thermal modelling of dilution refrigerators, from heat loads to helium mixture behaviour at millikelvin temperatures
• Mechanical and thermal integration of control components for quantum computing (e.g., wiring, filters and amplifiers)
• Hamiltonian and open quantum system descriptions of how the cryogenic environment and control hardware affect qubit operation

• Strength in at least one of the following areas:
• Heat transfer and thermal simulation, computational fluid dynamics (CFD), or cryogenic or low-temperature physics
• Multiphysics and finite element modelling
• Open quantum systems, or tools such as QuTip (Quantum Toolbox in Python) or Sc qubits

Please apply as soon as possible, on November 12, 2026, at the latest through our recruitment system at BLUEFORS.COM. We will

review applications on an ongoing basis, and the position will be filled as soon as a suitable candidate is found.
