PsiQuantum is on a mission to build the first commercially useful quantum computer to solve humanity. Backed by Founders Fund and Redpoint.
About the role
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.
What they're looking for
- 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
More about this role
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,...
