PsiQuantum is on a mission to build the world’s first utility-scale, 1 million-plus qubit quantum computer, powered by breakthroughs in silicon photonics and quantum architecture. We were founded in 2015 by the world’s foremost experts in photonic quantum computing and have assembled a world class team dedicated to bringing the world-changing benefits of quantum computing into reality.

Quantum computing is anticipated to unlock the solutions to otherwise impossible computational tasks, with impact across science, technology, and business. By harnessing the laws of quantum physics, quantum computers are expected to dramatically outperform even the most powerful existing (or future) supercomputers and offer the potential to enable extraordinary advances across a broad range of applications including climate, energy, healthcare, finance, agriculture, transportation, materials design, and more, as well as deliver entirely new industries.

PsiQuantum is uniquely positioned to deliver on the promise of quantum computing. We have already demonstrated that it’s possible to manufacture core quantum components using the standard and scalable manufacturing processes of a world-leading semiconductor fab.

Our team is working across the full stack of quantum computing, from hardware design, manufacturing, and packaging through to quantum architecture and quantum algorithms. We’re a highly integrated, collaborative group and love tackling problems that span across interfaces.

There’s more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!


  • Work on-site at the external fab, and be the interface between Psiquantum and the external fab.
  • Perform data analysis, presentations, and documentation of the work.
  • Drive process integration development, with inputs from PsiQuantum and external Fab.
  • Provide hands-on support in the fab as needed.
  • Drive weekly wafer output and shipment.
  • Verify equipment start up & equipment qualification.
  • Work closely with PsiQ supply chain & operations to track wafer throughput.
  • Work with external fab to improve number of turns and increase output (cycle time reductions, steps simplifications, combine processes, yield improvements, improve variability & uniformity).
  • Actively track wafers in progress and report on their status.
  • Coordinate timely resolution of process challenges in the fab.


  • B.Sc., M.Sc., or Ph.D in Physical Sciences or Engineering.
  • 5+ year of R&D experience with process development with emphasis on process integration. For instance, development of a new process flows, integration of new modules in a process flow, or optimization of a process flow.
  • Proficient with JMP or similar data analysis tool.
  • Effective communication and detailed documentation.
