Job description

Description

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.

Requirements

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.
