Job description

Quantum Engineer, Readout at IQM Quantum Computers, Espoo, FI. A mid-level full time position in the Engineering team, listed under hardware engineering.

We are looking for a Quantum Engineer (Mid-level to Senior) with a scientific mindset to develop new readout techniques for superconducting quantum processors and to support our quantum error correction (QEC) efforts towards scalable quantum computing. The role is R&D-focused: you will develop novel methods to improve readout performance, not only through new calibration methods but also by improving QPU design and hardware. You will work closely with experienced engineers and researchers in our Readout team across Espoo and Munich, and with our QPU design, fabrication, calibration, software, and error correction teams.

This position sits at the intersection of quantum physics research, QPU hardware and software, offering strong opportunities for learning and growth. You will work on state-of-the‑art quantum computers. The role is based at our headquarters in Espoo, Finland. Working from our Munich office in Germany is also possible.

What you’ll actually do

• Develop and test new readout techniques for quantum processors, including mid-circuit and terminal readout
• Develop new calibration methods and benchmarking workflows that our calibration teams use every day
• Turn your findings into improvements in QPU design and hardware
• Implement your methods in our software framework and validate them on real quantum hardware
• Analyze experimental data and identify what limits readout performance
• Model and simulate readout using theory such as circuit QED, to guide new methods and QPU designs
• Collaborate with cross-functional teams (hardware, software, fabrication)
• Document results, present findings internally and externally, and contribute to patent applications for new methods

What we’re looking for

• Hands‑on or theoretical experience with qubits of any modality, such as running qubit measurements or circuit QED theory
• Experience with software development, including Python and its ecosystem; familiarity with git version control is a plus

Nice to Have

• Exposure to quantum error correction
• Experimental lab work or measurement systems
• Cryogenic microwave engineering
• Experience with parametric amplifiers, such as JPAs or TWPAs
