About the integrated photonics engineer role

  • Design and run experiments to characterise integrated photonic circuits across several optical wavelengths
  • Characterise optical circuit switch performance across operating conditions and wavelengths
  • Test and analyse devices containing directional couplers, interferometers and electro-optic modulators
  • Build automated experiment control and data acquisition, preferably in Python
  • Work with design teams to troubleshoot devices and improve the next iterations, and document procedures and results
  • Help develop scalable testing methods for large photonic systems

What PsiQuantum is looking for

  • A PhD in photonics, physics, electrical engineering or a related field
  • A strong experimental background in integrated optics and photonic circuit characterisation
  • Hands-on experience with directional couplers, Mach-Zehnder interferometers (MZI/AMZI) and phase shifters
  • Python for automation and data analysis, and experience with complex optical measurement setups

Nice to have

  • Industry experience in photonics or semiconductor device testing
  • Electro-optic and thermo-optic tuning
  • Optical circuit switching architectures in data-centre networks, including switch performance metrics
  • Wafer-scale or high-throughput photonic testing, and knowledge of quantum optics or photonic quantum systems

How to prepare for this application

  • Device physics: explain how a directional coupler and an MZI work, and what limits their extinction ratio and loss.
  • Measurement: be ready to design a measurement of insertion loss and crosstalk for a switch across wavelengths.
  • Automation: bring an example of Python code that controlled instruments and processed data.
  • Troubleshooting: prepare a story where you traced a device problem back to design or fabrication.
  • Scale: think about what changes when you test thousands of devices instead of a handful.

About PsiQuantum

PsiQuantum was founded in 2016 with a single aim: to build and deploy million-qubit, fault-tolerant quantum computers. Its architecture is based on silicon photonics, using high-volume semiconductor manufacturing, including partners such as GlobalFoundries, to make the photonic chips its machines are built from.
