Senior Photonics Engineer, Optical Interfaces

About the role

<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>We are seeking a Senior Photonics Engineer to develop ultra-low-loss optical interface solutions between dissimilar, exploratory, waveguiding platforms. This role combines device concept development, optical simulation, and hands-on experimental validation to assess and mature new approaches for mode conversion and coupling. The successful candidate will combine creativity in photonic device design with strong engineering judgement, identifying solutions that are both high-performing and practical to deploy. Working closely with internal teams and expert external partners, they will help guide the development of advanced optical interfaces. We welcome applicants from both advanced industrial photonics environments and leading research groups who combine strong physical intuition with practical experimental and engineering judgement.</p> <p><strong>Responsibilities:</strong></p> <div class="ak-renderer-extension " data-layout="default" data-local-id="b6839916-5a17-444d-935b-16560225fcb8"> <div class="ak-renderer-extension-inner-wrapper ak-renderer-extension-overflow-container css-1xdhyk6"> <div class="_19itglyw _vchhusvi _r06hglyw _ca0q1b66" data-testid="field-container"> <div class="_1e0c1txw _vchhusvi _2lx21bp4 _1bah1fhb"> <div class="_19itglyw _vchhusvi _r06hglyw" data-testid="field-input-paragraph-rich-text-view-3"> <div class="ak-renderer-w
