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.
Come join us.
Job Summary:
PsiQuantum is seeking an Integrated Photonics Engineer to support the characterization and validation of advanced photonic circuits underpinning our quantum computing platform.
In this role, you will design and execute experiments to test complex optical circuits, working closely with circuit designers and system engineers. You will play a key role in developing automated experimental workflows and advancing our understanding of integrated photonic devices.
Responsibilities:
- Design and execute experiments to characterize integrated photonic circuits across multiple optical wavelengths.
- Test and analyse devices incorporating components such as directional couplers, interferometers, and EO modulators.
- Develop automated experimental control and data acquisition systems (Python preferred).
- Characterize complex integrated optics-based circuits and interpret experimental results.
- Collaborate with design teams to troubleshoot device performance and improve future iterations.
- Generate detailed reports and documentation for experimental procedures and results.
- Contribute to the development of scalable testing methodologies for large-scale photonic systems.
Experience/Qualifications:
- PhD in Photonics, Physics, Electrical Engineering, or a related field.
- Strong experimental background in integrated optics and photonic circuit characterization.
- Hands-on experience with key components such as directional couplers, interferometers (MZI/AMZI), and phase shifters.
- Proficiency in Python for experiment automation and data analysis.
- Experience working with complex optical measurement setups.
Desired Skills:
- Industry experience in photonics or semiconductor device testing.
- Familiarity with electro-optic and thermo-optic tuning mechanisms.
- Experience with wafer-scale or high-throughput photonic testing.
- Knowledge of quantum optics or photonic quantum systems.
