At IQM, we build world-leading quantum computers for the well-being of humankind. We design systems to tackle computational challenges beyond the practical limits of classical machines. Our work sits at the edge of science and engineering. It's complex, demanding, and deeply collaborative. We turn deep research into reliable, full-stack systems that drive discoveries in fields like medicine, energy, and technology, reshaping how the world computes.

Join the team that gives quantum a heartbeat.

The work

We are looking for a QEC Calibration Engineer to join our team in Munich, Germany, or Espoo, Finland, focusing on developing and improving quantum operations required for quantum error correction (QEC).

In this role, you will work on calibration, benchmarking, and optimization of quantum processors to enable fault-tolerant quantum computing. You will implement and execute QEC experiments, analyze system performance, and contribute to the development of control software and calibration strategies aligned with IQM’s QEC roadmap.

This is a hands-on role at the intersection of quantum hardware, calibration, and software, where your work will directly impact the performance and scalability of IQM’s quantum systems.

What you’ll actually do

• Improve QPU calibration methods for QEC applications

• Develop quantum operations such as readout, reset, leakage reduction

• Implement, execute, and analyze QEC benchmark and demonstration experiments

• Contribute to the development of quantum control software and calibration workflows

• Identify and define technology-stack requirements for QEC

• Analyze experimental data and report results to stakeholders

• Collaborate with cross-functional teams including Gates, Calibration & Benchmarking, software, and QPU design

• Support knowledge sharing and mentoring of team members and interns

• Participate in daily and weekly technical meetings

What we’re looking for

• Strong understanding of quantum computing and QPU physics

• At least two years of experience calibrating superconducting QPUs. Examples include experience calibrating single-qubit gates, two-qubit gates, readout, or other relevant quantum operations

• Demonstrated experience with scientific software development, especially in physics-related environments, specifically

  • Strong Python programming skills and familiarity with its ecosystem

  • Experience with software development workflows, for instance unit testing, documentation, git version control

• Experience with data analysis in Python

• Ability to execute experiments independently and analyze complex data

• Strong analytical and problem-solving skills

• Good communication skills and ability to work across teams

Education & experience

• PhD or MSc in Physics, Engineering, Computer Science, or related field (or equivalent experience)

• Several years of relevant experience in quantum computing or related areas

Nice to have

• Experience calibrating large-scale superconducting QPUs

• Experience developing leakage reduction units or reset methods

• Experience running quantum error correction experiments

• Knowledge of QEC theory and error modeling

What kind of person will thrive in this role?

• Hands-on and motivated to work on real quantum hardware challenges

• Curious and driven to improve QEC performance and system-level behavior

• Collaborative and able to work across interdisciplinary teams

• Detail-oriented with a strong data-driven mindset

• Ambitious about advancing fault-tolerant quantum computing

Why IQM?

• Full-stack quantum computing: From quantum hardware to software layers and beyond, we build across the full-stack.

• High-performance playground: We aim high, and we know sustainable performance only works when life outside work does too—hybrid setups, flexible hours.

• Never the smartest: Expect to learn constantly. You won't always be the smartest person in the room, and that's the point.

• Approachable leadership: Flat hierarchy, direct access. Feel free to approach any leaders. They're friendlier than they look!

• The sweet spot: Big enough to matter. Small enough to move fast. Growing between a startup and a corporation. We’re in the phase where top performers get noticed.

• Bigger than IQM: Our people build know-how for the entire quantum ecosystem. We publish papers, run hackathons, and help shape a market that's still being defined.

The future of computing won’t build itself. You might be one of the few who do.
