Research Scientist-Quantum Packaging Design

Quantum Machines is a global leader in hybrid control systems for quantum computing, a field on the verge of exponential growth.

Our innovative hardware and software offer a groundbreaking approach to controlling quantum computers, scaling from individual qubits to arrays of thousands.

We are looking for a highly experienced Research Scientist for Cryogenic Electronics Team.

If you are super talented, ready to learn new things, and a real team player – your place is with us.

Why QM 

• Direct path from blue-sky research to deployed quantum-computing hardware. 
• Access to in-house qubit-control electronics, cryo-RF labs and top academic collaborators. 
• Competitive salary, stock options, pension and six weeks’ vacation. 
• Travel budget for collaborator site visits and major conferences. 

Responsibilities:

• Design and validate multilayer superconducting packaging that links qubit stacks to cryogenic electronics. 
• Run high-fidelity finite-element simulations to probe microwave integrity etc,and turn the results into design rules. 
• Specify test and outsourced fabrication, and lead cryogenic bring-up & metrology (VNA, TDR, qubit benchmarks). 
• Correlate packaging performance with qubit coherence and noise spectra in collaboration with QM device physicists and external partners. 
• Communicate results via internal white papers, conference abstracts and partner workshops, always safeguarding project confidentiality. 

Requirements:

• PhD (or MSc + equivalent experience) in physics, electrical engineering or materials science with 3 years research on cryogenic or high-frequency hardware. 
• Expert-level skill with 3-D EM/FEM tools. 
• Clear scientific writing and storytelling in English; comfortable syncing work across time zones. 
• EU citizenship or Danish work-permit eligibility; Danish language optional. 
• Hands-on familiarity with dilution refrigerators, superconducting-qubit measurement, and low-temperature RF wiring is a strong plus. 
• If your path is unconventional but the science excites you, we still want to hear from you.
