Photonics Circuit Designer (Modelling and Simulation) at PsiQuantum (Palo Alto)

Job Description

PsiQuantum is hiring a Photonics Circuit Designer in Palo Alto to model, simulate and optimise high-performance integrated photonic circuits, including the photon-pair sources at the heart of its general-purpose silicon photonic quantum computer.

At a glance

• Role: Photonics Circuit Designer
• Where: Palo Alto, California, USA
• Pay: US$140,000–165,000 base in the Bay Area (US$120,000–145,000 elsewhere in the US)
• Level: PhD or equivalent in electrical engineering or physics, plus 5 years in integrated photonics
• Apply: open until filled (re-checked 11 October 2026)

About the photonic circuit modelling role

• Build data-driven models of linear photonic devices at different scales and with different methods
• Design and optimise photonic circuits
• Fully simulate complex circuits, including photon-pair generation through spontaneous four-wave mixing
• Draw circuit schematics and coordinate circuit layout
• Analyse data to understand how devices and circuits perform
• Work with component design and characterisation teams to validate circuits

In a photonic quantum computer, every decibel of optical loss and every imperfect component turns into errors, so the quality, consistency and manufacturability of photonic devices matter as much as the architecture. These engineering roles work on that foundation.

What PsiQuantum is looking for

• A PhD or equivalent in electrical engineering or physics
• 5 years of relevant work or academic research in integrated photonics
• In-depth knowledge of photonic devices, their performance metrics and test methods
• Extensive photonic design experience with commercial software, and experience with circuit layout
• Extensive Python for scientific work and data handling, plus strong communication

Nice to have

• Experience with the Wolfram Language

Pay and location

PsiQuantum lists a US base pay range of US$120,000–145,000, or US$140,000–165,000 in the Bay Area. The role is based in Palo Alto, California.
