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

As a Senior/Staff Quantum Error Correction Engineer, you will play a key role in advancing the core technology behind IQM’s quantum computers. You will design and optimize quantum error-correcting codes, fault-tolerant protocols, and decoding algorithms that directly impact system performance and scalability.
Working at the intersection of theory, software, and hardware, you will collaborate closely with quantum hardware, software, and research teams to bring error correction from theory into experimental reality. Your work will push state-of-the-art research forward while enabling practical, scalable quantum computing.

What you’ll actually do

• Design and optimize quantum error-correcting codes, fault-tolerant protocols, and decoding algorithms

• Develop and benchmark simulations to evaluate QEC performance and scalability

• Contribute to and run quantum error correction experiments on IQM hardware

• Build and maintain robust software libraries for QEC and integrate them into broader systems

• Collaborate closely with hardware, software, and research teams to bring QEC into practice

• Contribute to research, publish results, and help shape technical direction in QEC

What we’re looking for

• Strong expertise in quantum error correction, quantum computing, and quantum information

• Solid programming skills (Python) and experience with quantum tools (e.g., Stim, Qiskit)

• Experience with QEC codes, fault-tolerant protocols, or decoding algorithms

• Strong analytical skills and ability to solve complex, abstract problems

• Experience building scalable algorithms or prototype systems

• Ability to communicate complex topics clearly and collaborate across teams

• MSc or PhD in a relevant field (PhD preferred), with several years of experience in QEC or related research

• Track record of scientific publications in quantum error correction or related 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.
