• 2 – 15 years of experience in quantum technology, RF/microwave engineering or related domains.
• Passion to build world-class quantum technologies.

Technical skills required

• RF / microwave design and measurement
• Quantum-limited amplifiers (HEMT, TWPA, JPA and similar)
• Cryogenic systems and low-noise instrumentation
• Strong understanding of quantum circuits, cryogenics and microwave systems
• Vector network analysis and time-domain measurement
