Quantum Integration Engineer

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. As a Quantum Integration Engineer, you ensure IQM quantum computers operate reliably across cloud, customer, and internal R&D environments. You work hands on with calibration, system stability, software updates, and incident resolution. You collaborate closely with R&D teams, acting as an expert for our systems. You identify performance deviations, debug complex issues, and translate real system behavior into structured feedback that improves the next generation of our technology used for research worldwide. Your work ensures that our quantum computers are not just built, but operational, stable, and scientifically usable. Operate and maintain IQM quantum computers across cloud and customer environments, ensuring high availability and stable performance. Plan and execute calibration and service activities aligned with customer and user needs. Perform on-site debugging and testing. Analyze system performance, identify deviations, and troubleshoot hardware and software issues affecting system behavior and stability. Contribute to L2 incident resolution and technical support for customer systems. Perform testing, debugging and calibration during customer system deliveries and commissioning. Act as a key interface between production systems and R&D, providing structured technical feedback to improve performance, usability, and reliability. Develop and refine service documentation, procedures, and laboratory best practices. We are looking for a master's degree in quantum physics, experimental physics, engineering, or a closely related field. A PhD is considered an advantage. Experience working with complex experimental or high-tech systems such as superconducting circuits, cryogenic setups, RF systems, or similar advanced hardware environments. Strong understanding of quantum computer architecture and calibration, as well as system level performance dependencies. Experience in troubleshooting hardware and software integration issues in research or production environments. Ability to analyze experimental data and identify root causes of performance deviations. Proficiency in Python or a similar programming language. Experience documenting procedures, experiments, and technical findings in a structured way. Ability to take ownership of tasks, manage multiple priorities, and collaborate effectively across R&D, engineering, and customer facing teams in various time zones. Commitment to reliability, safety, and continuous improvement. Excellent communication skills in English and Japanese, with the ability to explain complex technical topics to both technical and non-technical audiences. Willingness and ability to travel to customer premises as needed. Seen as beneficial: Experience with superconducting quantum computing systems and cryogenic measurement setups. Experience operating quantum computers in cloud or production environments. Familiarity with incident management processes in online or high availability systems. Experience supporting external research users or industrial customers. 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. We'll start interviews and move forward with hiring as soon as we meet strong candidates.
