System Integration Engineer

QuantWare is the world's leading manufacturer of superconducting quantum hardware. As a hyper-growth scale-up with a global customer base, our mission is to accelerate the advent of the quantum computer. We push the boundaries of what's possible in our field. We work on making the world’s largest quantum processors as fast as possible.
At QuantWare, we’re not just producing quantum hardware for the hyperscalers of tomorrow; we’re working on technology that will change the world. To make that ambition a reality, we need exceptional people who drive real impact. That’s where you come in. 

As a System Integration Engineer, you’ll play a crucial role in bringing together our subsystems into coherent, high-performing quantum hardware. You will define system specifications, lead validation efforts, and ensure seamless integration and optimisation of all technical components. Your work will be essential as we scale to increasingly complex systems and deliver on the promise of quantum computing.

• Plan and manage the integration of cutting-edge scaling technologies developed by our R&D teams into next-generation quantum processors

• Develop and coordinate integration test plans with cross-functional teams

• Lead the definition and formalisation of system engineering processes across the organisation

• Establish scalable, documented integration procedures to support system growth

• Investigate and resolve integration issues and technical anomalies, ensuring alignment with specifications and overall performance targets

• 4+ years of experience in system engineering for deep-tech or low-volume hardware

• Hands-on experience with systems exposed to extreme temperature environments (e.g., aerospace, cryogenics, telecommunications, defense)

• Familiarity with superconducting technologies

• A background in quantum physics, microwave/RF/electrical engineering, or a related field (PhD is a plus)

• Experience with electromagnetism, semiconductor/superconductor chips, or MEMS

At QuantWare, you’ll be part of a high-performing team of world-class experts in an ambitious, fast-moving environment. From day one, you’ll have the trust, tools, and support to do your best work. Here’s what you can expect:
