Photonic Design Automation Engineer

Psi Quantum's mission is to build the first useful quantum computers—machines capable of delivering breakthroughs. Since 2016 our focus has been to build and deploy million-qubit, fault-tolerant quantum systems.

Quantum computers harness the laws of quantum mechanics to solve problems beyond the reach of classical supercomputers and AI systems. Their impact spans energy, pharmaceuticals, finance, agriculture, transportation, materials, and other industries.

Our architecture is based on silicon photonics. By leveraging advanced semiconductor manufacturing—with partners like Global Foundries—we use high-volume processes that produce billions of chips. Photonics offers scale: photons don’t feel heat, are immune to electromagnetic interference, and integrate with cryogenic cooling and fiber-optic infrastructure.

In 2024, Psi Quantum announced government-funded projects to support building our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale.

Psi Quantum also develops algorithms and software to make these systems commercially valuable. Our application, software, and industry teams work with Fortune 500 companies—Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, Mitsubishi Chemical—to prepare quantum solutions for real-world impact.

Quantum computing represents a fundamental shift—and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.

Come join us.

Quantum computing promises to solve important problems that could never be solved on any conventional computer. At Psi Quantum we're building a general-purpose silicon photonic quantum computer to tackle these problems.
