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 Quantum Control Software Engineer to join our Gates team, where software engineering, experimental physics, and quantum hardware development come together to enable high-fidelity quantum operations.

In this role, you will contribute to the research and development of single- and two-qubit gate implementations for superconducting quantum processors. You will develop software components and calibration routines that are critical for benchmarking, calibration automation, and quantum processor performance optimization—ultimately supporting IQM’s roadmap toward large-scale quantum error correction.

This is a unique opportunity to work at the intersection of quantum control, scientific software development, and experimental quantum computing, contributing both to daily calibration workflows and long-term technical innovation.

What you’ll actually do

• Develop and implement software for quantum control, calibration, and benchmarking

• Contribute to the development of single- and two-qubit gate operations

• Build and maintain calibration routines for superconducting quantum processors

• Improve and extend software features supporting calibration automation and benchmarking

• Identify performance bottlenecks and collaborate with technical teams to improve QPU performance

• Participate in regular calibration activities and experimental workflows

• Analyze, document, and report results to technical stakeholders

• Contribute to the scientific and technical planning of gate development activities

For senior-level candidates:

• Mentor and support junior engineers, newcomers, and interns

• Provide guidance on technical focus areas and software development practices

• Contribute to architectural and technical leadership decisions

What we’re looking for

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

• Strong Python programming skills and familiarity with its ecosystem

• Experience with software development workflows, including:

  • Unit testing

  • Documentation

  • Version control (git)

  • CI/CD practices

• Good understanding of quantum computing, especially quantum gate implementations

• Strong analytical and organizational skills

• Ability to independently solve technical problems and collaborate effectively across teams

Education & experience

• PhD in Physics, Quantum Technology, Computer Science, or related field

• Or equivalent practical experience after MSc

• Senior-level candidates typically have 3+ years of relevant experience

Nice to have

• Experimental experience with quantum control and benchmarking methods

• Hands-on experience with electronics used to control superconducting qubits or similar systems

• Background in experimental quantum hardware environments

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.
