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

IQM is looking for a Quantum Engineer (Experiment) to join our Coherence team, focusing on characterizing and improving the coherence of superconducting qubits—one of the key performance drivers of quantum processors.

In this role, you will work hands-on with quantum devices, performing measurements, analyzing results, and contributing to the development of new protocols for identifying and mitigating noise mechanisms. Your work will directly support IQM’s technology roadmap and improve the performance of next-generation quantum processors.

You will collaborate closely with design, fabrication, and other QPU technology teams, helping bridge experimental results with device and system improvements.

What you’ll actually do

• Characterize superconducting qubits and test devices using in-house measurement tools

• Install devices, run experiments, and analyze measurement data

• Interpret and report experimental results to stakeholders

• Contribute to the development of coherence metrology methods

• Support R&D and internal projects focused on improving qubit coherence

• Identify noise mechanisms and contribute to strategies for performance improvement

• Continuously improve measurement workflows, methodologies, and KPIs

• Participate in daily and weekly team meetings and cross-team collaboration

• Share knowledge and insights with design, fabrication, and other technical teams

What we’re looking for

• PhD in experimental physics, electrical engineering, or a related field (or equivalent experience)

• Minimum 2 years of experience measuring superconducting qubits or similar systems

• Understanding of superconducting qubit physics and resonator systems

• Experience with Python programming and software development practices

• Familiarity with version control systems (e.g. git)

• Knowledge of microwave measurement techniques

• Strong analytical and problem-solving skills

• Good communication skills in English

Nice to have

• Experience in noise or dissipation characterization in superconducting qubits

• Experience of working with cryogenic systems

• Familiarity with advanced experimental techniques for quantum systems

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.

• Explore our scientific publications.

We'll start interviews and move forward with hiring as soon as we meet strong candidates. Please submit your application soon.
