Experimental Quantum Physicist

ABOUT SYGALDRY Sygaldry Technologies is building quantum-accelerated AI servers to exponentially speed up training and inference for AI. By integrating quantum and AI, we're accelerating the path to superintelligence, and addressing the problem of rising compute costs and energy bottlenecks. Sygaldry AI servers combine multiple qubit types within a single, fault-tolerant architecture to deliver the combination of cost, scale, and speed necessary for advanced AI applications. We pioneer new domains in physics, engineering, and AI, tackling the hardest challenges with a grounded, optimistic, and rigorous culture. We're looking for individuals ready to define the intersection of quantum and AI and drive its profound global impact. ABOUT THE ROLE We are seeking an experimental physicist with strong laboratory experience in atomic, optical, or quantum systems. You will play a key role in building and operating cutting-edge experimental platforms for qubit control, measurement, and scaling. The ideal candidate enjoys hands-on work, creative problem-solving, and collaborating across disciplines to make new quantum technologies a reality. WHAT YOU'LL WORK ON - Design, construct, and characterize precision optical and/or cryogenic systems for quantum experiments. - Understand and implement protocols for qubit preparation, control, and readout. - Integrate control electronics, laser or rf and microwave systems, and data acquisition. - Analyze experimental results and optimize system performance. - Cross-team collaboration to guide system design and development. YOU MAY BE A GOOD FIT IF YOU HAVE - Ph.D. in Physics, Applied Physics, Electrical Engineering or a related field. - Hands-on experience working with advanced laboratory instrumentation and quantum systems including AMO physics, solid-state and/or superconducting systems. - Familiarity with qubit control, spectroscopy, or precision measurement techniques. - Strong background in experimental design, data analysis, and scientific problem solving. - Experience with Python or similar tools for experiment automation. - Excellent communication skills and a collaborative mindset. HOW WE’RE DIFFERENT At Sygaldry, curiosity and intellectual courage drive our work. We approach ambitious challenges with a grounded, optimistic, and rigorous culture and know that kind people build the strongest teams. We prioritize mission over ego and collaborate openly with a strong sense of shared purpose. We dream big, yet we execute with a love of detail. We’re looking for scientists, engineers, and operators to forge new paths with us at the intersection of quantum and AI.
