Silicon Photonics Design & Integration Engineer

Location: Palo Alto, CA

Department: Silicon Photonics

Getting our silicon photonic integrated circuits from design to foundry — correctly integrated, verified, and delivered on schedule — is critical to our product cadence. We are seeking a Silicon Photonics Design & Integration Engineer to own PIC integration and tape-out, working in a fast-paced, cross-functional environment with high visibility across device design, electronics, systems, and packaging teams. This is not a passive coordination role; the right candidate brings strong silicon photonics fundamentals, practical tape-out experience, and the proactive ownership mindset to drive integration work to completion across teams.

Responsibilities

• Integrate photonic devices and circuit blocks from multiple contributors into complete PIC designs, maintaining performance, layout integrity, and manufacturability throughout.
• Drive silicon photonics tape-outs from design freeze through foundry submission — ensuring compliance with PDK requirements, foundry design rules, and DRC/LVS sign-off.
• Work with photonic designers to drive layout implementation, verification, and tape-out readiness; identify and resolve integration conflicts early in the design cycle.
• Serve as a technical interface with silicon photonics foundry partners to resolve design rule, integration, and manufacturability issues.
• Collaborate closely with electronics interface (EI), system architecture, and packaging teams to ensure photonic circuits integrate correctly with electrical interfaces, system requirements, and packaging constraints.

Required Qualifications

• Strong understanding of silicon photonic device physics and operation, with practical experience designing or integrating silicon photonic devices or circuits.
• 5 or more years of relevant industry experience in silicon photonics design, integration, or tape[1]out.
• Familiarity with silicon photonics process technology, layer stacks, and fabrication constraints as they relate to integration and layout decisions.
• Experience with PDK-based design flows and photonic layout tools such as Cadence, KLayout, Luceda IPKISS, or equivalent.
• Demonstrated experience supporting PIC layout integration and tape-out activities, including DRC verification and foundry submission.
• Strong cross-functional ownership mindset — able to proactively drive integration work to completion and resolve conflicts across design, EI, systems, and packaging teams.
• Experience working directly with silicon photonics foundries on integration and manufacturability issues.

Preferred Qualifications

• Experience integrating complex photonic circuits or multi-function subsystems.
• Hands-on experience with photonic device characterization or validation.
• Experience collaborating across photonics, electronics interface, system, and packaging teams on co-design or integration challenges.

Education

Ph.D. in Electrical Engineering, Photonics, Applied Physics, or a closely related discipline. Candidates with relevant industry experience and a demonstrated track record of PIC integration and tape-out ownership may be considered without a Ph.D.
