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
The Principle Optical Fiber Architect reports into the System Design organization. This role leads the Optical Distribution Network (ODN) design and integration for current and future systems. This includes the design, development, integration and validation of the fiber network and hardware to support the complex fiber network needed in our quantum systems. They will be responsible to bridge component-level fiber link designs and top-level system requirements, ensuring functionality, reliability, and performance.
What they're looking for
- M.S. or PhD in Physics, Optical or Electrical Engineering with 10+ years industry experience
- >5+ years experience designing, validating and testing fiber networks and fiber optical systems
- Deep expertise in fiber optics, including loss mechanisms, dispersion, nonlinear effects, polarization, and phase stability
- Experience designing fiber optic systems, fiber networking and working with advanced splice equipment and optimization, fiber handling and routing
- Experience working with optical test equipment including power meters, optical backscatter reflectometers (OBR), optical spectrum analyzer (OSA)
- Experience working with instrumentation used in the photonics and/or the electronics industry
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,...
