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—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 Layout 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 software 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 layout infrastructure and automation tools.
- Develops comprehensive documentation for tape‑outs.
Experience / Qualifications:
- Master’s degree, PhD, or equivalent in Electrical, Computer Engineering, Material Science, Physics.
- 2 years of relevant work or academic research experience in integrated photonics and layout.
- Strong fundamentals of the design and characterization of photonic devices and circuits.
- Proven proficiency in Python programming for numerical analysis, data manipulation, automation, and photonic circuit layout.
- Experience with collaborative code management tools such as Git.
- Experience with silicon photonic manufacturing processes and foundry tape‑outs.
- Proven team player with an ability to work effectively across departments, sites, and time zones.
- Excellent verbal and written communication skills.
- Strong analytical and detail‑oriented problem‑solving skills.
