The ideal candidate will have expertise in novel integrated photonics device design and metrology, gained through a Ph.D. or industry experience.
• Responsibilities
• Design and develop complete Photonic Integrated Circuits (PICs), from fundamental component blocks to full-circuit implementations, with a strong emphasis on active device integration.
• Generate, verify, and prepare fabrication-ready layout files, ensuring compliance with foundry Process Design Kits (PDKs) for external fabrication.
• Conduct systematic design analysis, including optimization and parametric studies, to guide design decisions.
• Support the entire design-to-fabrication pipeline, from initial concept through tapeout, coordinating closely with cross-functional teams and external partners.
• Collaborate with program leadership, Technical Program Managers (TPMs), and researchers on PIC designs that align with overall program objectives.

Minimum Qualifications:

• MS or Ph.D. degree in Electrical Engineering, Optical Sciences, Physics, or a closely related field.
• 3+ years of hands-on experience in the design, simulation, and layout of PICs for visible or IR wavelengths on platforms such as Si, SiN, LiNbO, or BTO.
• 3+ years of experience utilizing photonic device simulation and electromagnetic modeling tools for both component and circuit-level analysis (e.g., Lumerical FDTD/MODE/DEVICE, Ansys Photonics, Synopsys RSoft, or COMSOL Multiphysics).
• 2+ years of experience with PIC layout tools and GDSII generation (e.g., KLayout, Cadence Virtuoso, gdsfactory, or equivalent), including familiarity with foundry PDK integration and design rule verification.
• 2+ years of experience with scientific programming (e.g., Python or MATLAB) for scripting, design automation, and analysis.
• 1+ years of experience supporting or executing PIC tapeouts at a commercial semiconductor foundry, including an understanding of fabrication process constraints (e.g., propagation losses, sidewall roughness, etch non-idealities).

Preferred Qualifications:

• 3+ years experience in active PIC design, fabrication, and validation, particularly for visible wavelengths on LiNbO or BTO platforms.
• 3+ years of experience in design space exploration, sensitivity analysis, and statistical performance/yield modeling for photonic circuits.
