Silicon Photonics Design Engineer

PsiQuantum is seeking a creative and innovative Silicon Photonics Design Engineer to help push the boundaries of high-performance fiber-to-chip coupling for quantum photonic integrated circuits. This role sits at the intersection of device physics, packaging, and experimental validation, and offers ownership across the full development cycle – from concept and simulation to tapeout support, testing, and model closure.

Requirements

• Design, model, and analyze novel fiber-chip coupling concepts suitable for large-scale quantum computing systems.
• Own coupling device development across the full lifecycle, including simulation, layout, experiment design, data analysis, and model closure.
• Contribute to photonic tapeouts, including hands-on layout, DOE definition, and coordination with cross-functional stakeholders.
• Collaborate with test engineers to plan and execute automated, high-volume measurements, and develop new test methodologies as needed.
• Analyze measurement data to identify performance trends, limitations, and optimization opportunities, and clearly communicate results to diverse technical audiences.
• Work closely with foundry, packaging, and test teams to validate, screen, and continuously improve fiber-chip coupling performance.

Benefits

• Full time roles are eligible for equity and benefits.
