Quantum Electronics Engineer - IC Design & Cryogenics
Mission PsiQuantum’s mission is to build the first useful quantum computers—machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems. Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact spans energy, pharmaceuticals, finance, agriculture, transportation, [and] materials, fueling foundational industries.
Our architecture leverages silicon photonics, using the advanced semiconductor manufacturing industry (including partners like GlobalFoundries) to produce billions of photonics chips for telecom and consumer electronics. Photonic solutions offer unique advantages: no heat sensitivity, immunity to electromagnetic interference, seamless integration with cryogenic cooling, and compatibility with standard fiber-optic infrastructure.
About the Role
In 2024, PsiQuantum announced groundbreaking, government-funded projects for our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives underscore recognition that quantum computing will shape strategic AND economic success—and that scale is the defining challenge today.
Alongside building hardware, we develop algorithms and software to unlock quantum advantages. Our teams collaborate with global industry leaders (Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, Mitsubishi Chemical) to prepare solutions for real-world quantum impact.
