Silicon Photonics Engineer at PsiQuantum (Palo Alto, USA)

Job Description

PsiQuantum is hiring a Silicon Photonics Engineer in Palo Alto to design and implement next-generation photonic integrated circuits across the whole development cycle, from device design and layout to foundry tapeouts and root-cause analysis.

At a glance

• Role: Silicon Photonics Engineer
• Where: Palo Alto, California, USA
• Pay: US$139,800–164,300 base in the Bay Area; lower ranges in other zones
• 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 silicon photonics engineer role

• Work with device, hardware and system design teams on the overall development of photonic systems and devices
• Support foundry tapeouts with device design, design of experiments, layout, design verification, PDK development and software
• Write thorough documentation for tapeouts
• Resolve technical issues with components, parts or systems for component and system teams
• Use quantitative analysis to find the root cause of difficult technical problems and put corrective actions in place

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
• Strong computational and analytical skills applied to device design and performance evaluation
• In-depth knowledge of photonic devices, their metrics and test methods
• Extensive design experience with commercial tools such as the Lumerical suite, and layout experience with IPKISS, gdsfactory or similar
• Extensive Python for scientific work and data analysis, and clear communication

Pay and location

PsiQuantum lists base pay by location zone, from US$139,800–164,300 in zone 1 (Bay Area and New York City) to US$97,900–115,000 in zone 4 (for example Nashville, Phoenix and many remote locations). The role is listed in Palo Alto, California.
