R&D Engineer - Integrated Photonics

<p><span data-contrast="auto">PsiQuantum’s&nbsp;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.</span><span data-ccp-props="{}">&nbsp;</span></p> <p><span data-contrast="auto">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 will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.</span><span data-ccp-props="{}">&nbsp;</span></p> <p><span data-contrast="auto">Our architecture and approach&nbsp;is&nbsp;based on silicon photonics. By&nbsp;leveraging&nbsp;the advanced semiconductor manufacturing industry—including partners like GlobalFoundries—we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons&nbsp;don’t&nbsp;feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.</span><span data-ccp-props="{}">&nbsp;</span></p> <p><span data-contrast="auto">In 2024,&nbsp;PsiQuantum&nbsp;announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale.</span><span data-ccp-props="{}">&nbsp;</span></p> <p><span data-contrast="auto">PsiQuantum&nbsp;also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies—including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical—to prepare quantum solutions for real-world impact.</span><span data-ccp-props="{}">&nbsp;</span></p> <p><span data-contrast="auto">Quantum computing is not an extension of classical computing. It&nbsp;represents&nbsp;a fundamental shift—and a path to mastering challenges that cannot be&nbsp;solved&nbsp;any other way. The potential is enormous, and we have a clear&nbsp;path&nbsp;to make it real.</span><span data-ccp-props="{}">&nbsp;</span></p> <p><span data-contrast="auto">Come join us.</span><span data-ccp-props="{}">&nbsp;</span></p> <p><strong>Job Summary:</strong></p> <p data-renderer-start-pos="1">PsiQuantum is seeking an Integrated Photonics Engineer to support the characterization and validation of advanced photonic circuits underpinning our quantum computing platform.</p> <p data-renderer-start-pos="179">In this role, you will design and execute experiments to test complex optical circuits, working closely with circuit designers and system engineers.
