Job description

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

We are seeking a passionate Quantum Engineer, (Junior to Senior level) to join our Gates team in Espoo, Finland, or Munich, Germany. We are looking for candidates with a strong understanding of quantum gate control, a hands-on approach to problem-solving, and a proactive mindset. You’ll be at the forefront of research and development on quantum gate implementations for our superconducting quantum processors.

What you’ll actually do

• Developing and refining single- and two-qubit gates.
• Creating calibration and characterization routines.
• Analyzing gate fidelities and addressing their physical limitations.
• Collaborating across design, fabrication, software, theory, and other experimental teams to boost QPU performance.
• Contributing to efforts toward full quantum error correction.
• (Senior level) Mentoring junior team members and leading initiatives in technical focus areas.

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.

• Meet our people and learn more about IQM on our stories page.
• Explore our scientific publications.

Requirements

• Junior Quantum Engineer — M.Sc. degree in Physics, Quantum Engineering, or a related field.
• Quantum Engineer—Ph.D. degree in physics or a related discipline, or alternatively equivalent experience in quantum technologies.
• Senior Quantum Engineer — Postdoctoral or equivalent industrial experience in quantum technologies.
• Proven knowledge of gate-based quantum computation.
• Experimental experience with superconducting quantum bits or similar modalities.
• Python development experience (ideally in a quantum control framework).
• Strong analytical, documentation, and communication skills.
• Independent problem-solving abilities and drive to contribute to large-scale R&D.

Nice to Have

• Prior work on randomized benchmarking or other gate fidelity characterization methods.
• Experience with version control and collaborative software development.
• Background in calibration automation or quantum processor benchmarking.
• Experience with cryogenic hardware and technologies.
• For experienced engineers—Strong publication record in superconducting quantum computing, quantum gate control and characterization, or a related field.
