Whenever you spot abnormalities, you’ll search for root causes and countermeasures, together with your colleagues from Fabrication or Design. Product volume and complexity of our products increase - so the challenge is to stay one step ahead by continuously improving our measurement setups, software and processes.
Key Responsibilities:
- Own QuantWare’s cryogenic measurement setups: purchase and build them, and keep them state-of-the-art (maintenance, upgrades).
- Manage the hands-on physical operation of cryogenic quantum hardware, working directly with the dilution refrigerators.
- Develop measurement code to implement and refine Python-based routines for device characterization.
- Characterize quantum chips to evaluate and improve the performance of superconducting qubits and amplifiers - to guarantee QuantWare’s customers receive perfect devices and to support new product development and research.
Job Requirements:
- Education: master’s degree in physics or electrical engineering, preferably with a focus on quantum computing.
- Experience: Hands-on experience with programming, preferably Python.
- Knowledge: Experience with superconducting circuits and microwave measurement techniques is a plus, but not required.
- Skills: you are tech-savvy, learn fast and get things done: regardless if that means getting your hands dirty or deep in the python code. You enjoy solving problems and methodically improving our processes.

TECHNICAL & MARKET ANALYSIS | Appended by Quantum.Jobs
Experimental quantum engineering serves as the critical bridge between theoretical superconducting circuit design and the industrialization of reliable quantum processing units. This role is structurally necessary to transform laboratory-scale demonstrations into reproducible, high-yield hardware modules required for the scaling of quantum computers. By standardizing cryogenic measurement protocols, this function ensures the verification of device performance metrics essential for multi-node system integration. The global quantum value chain relies on these engineering competencies to mitigate current hardware reliability gaps and move toward fault-tolerant architectures. Market signals indicate that the maturation of the superconducting modality is gated by the throughput of device characterization, making this role a primary determinant of commercial deployment timelines. Its impact is measured by the successful transition from prototype research to the mass-manufacture of enterprise-ready quantum infrastructure.
The superconducting quantum hardware sector currently occupies a central position within the global quantum value chain, serving as the physical foundation upon which software stacks and application layers are built. As the industry shifts from fundamental physics to system engineering, the role of experimental validation becomes paramount. A major macro constraint facing this ecosystem is the "characterization bottleneck," where the time and infrastructure required to verify qubit quality lag behind the speed of design and fabrication. This mismatch hinders the rapid iteration cycles necessary to achieve large-scale, high-fidelity processors.
Current industry dynamics emphasize the transition toward modular hardware architectures, where interoperability between diverse sub-components is crucial. This necessitates standardized testing environments and automated characterization workflows that can function at scale. Public and private funding cycles, particularly within the European quantum ecosystem, are increasingly targeted toward high-Technology Readiness Level progression, moving hardware from laboratory prototypes to industrialized systems. This shift places significant pressure on the operational side of hardware providers to ensure consistent performance across increasing volumes of hardware.
Furthermore, the integration of quantum systems into classical High-Performance Computing environments requires hardware that meets rigorous classical engineering standards for uptime and reliability. The ecosystem is moving away from bespoke, laboratory-managed setups toward industrialized operations that utilize specialized cryogenic infrastructure and precise microwave engineering. Addressing these integration complexities is vital for reducing the total cost of ownership for quantum systems, which remains a significant barrier to commercial adoption. Consequently, the maturation of experimental engineering practices is the primary lever for overcoming current hardware scalability limits and enabling the next phase of the quantum revolution.
The capability architecture for this role type is built upon the synthesis of millikelvin-range cryogenic management, high-frequency microwave engineering, and automated software-defined characterization. Mastery of dilution refrigerator systems and signal chain optimization is the foundational layer that enables the stable operation of superconducting qubits. These capabilities are structurally essential for reducing environmental noise and maximizing coherence times, which directly affects the feasibility of error correction protocols.
Furthermore, the interface between hands-on physical manipulation and Python-based measurement automation represents a critical throughput multiplier. By developing robust codebases for device characterization, engineering teams enable the transition from manual, error-prone testing to high-throughput verification. This software-hardware coupling allows for the rapid identification of fabrication defects and design flaws, facilitating an accelerated feedback loop with fabrication and design departments. Expertise in microwave measurement techniques provides the diagnostic resolution required to certify device interoperability. Ultimately, these technical domains ensure that the hardware layer can reliably support the computational demands of the broader quantum ecosystem, driving the stability and performance required for real-world application benchmarks. - Accelerates the commercial availability of high-fidelity superconducting quantum processors for enterprise-scale deployment
