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 will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.
Our architecture and approach is based on silicon photonics. By leveraging 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 don’t feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.
In 2024, PsiQuantum 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.
PsiQuantum 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.
Quantum computing is not an extension of classical computing. It 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.

Job Summary
Quantum computing promises to solve many important problems that could never be solved on any conventional computer. At PsiQuantum, we’re building a general-purpose silicon photonic quantum computer to tackle these very problems.
We are looking for an energetic, highly motivated Photonic Integrated Circuit (PIC) engineer who will be responsible for the design, layout, and verification of photonic integrated circuits for a linear optic quantum computer (LOQC).
We’re looking for a creative and innovative individual with strong fundamentals in the design, optimization, layout, and fabrication of integrated optical devices. This role is focused on pushing the boundaries of high-performance integrated photonic components and circuits. The role requires excellent python skills, experience with python-based layout tools and foundry tape outs, and experience with collaborative coding environments such as git.
Responsibilities
- Interacts with device, hardware, and system design teams to assist in overall development of Photonics and Quantum Optics photonic systems and devices.
- Supports foundry tape outs with photonic device design, design of experiments, layout, design verification, PDK development, and software development.
- Develops comprehensive documentation for tapeouts.
- Provides multi-disciplinary support to component and systems teams by resolving technical issues associated with components, parts, or systems.
- Applies quantitative analysis in determining root cause of highly technical problems and proposes, develops, and implements solutions for corrective action.
Experience/Qualifications
Education
- PhD or equivalent in Electrical Engineering, Physics, Materials Science.
Experience
- 5+ years of relevant work or academic research experience in integrated photonics.
Knowledge, Skills, And Abilities
