Silicon Photonics Design Engineer

The successful candidate will join our Photonic Design team developing cutting-edge silicon photonics devices. This person will learn and grow rapidly, while having enormous impact across all technical and business activities in a fast-paced startup environment.

• Design, simulate, and optimize silicon photonic active and passive components
• Implement design automation for simulation and layout tools
• Support design and verification of photonic layout design
• Collaborate with integration and test teams to optimize design based on aligned requirements
• Contribute to the development of new Intellectual Property related to photonic designs

• Strong desire to contribute to a high-impact photonics company
• Ph.D. in Electrical Engineering or a related field, or M.S. with 2+ years of industry experience
• Practical experience in modeling photonic devices or systems with design software (Lumerical, Tidy3D, or similar)
• Eligible to work in the United States
• Experience in high-speed modulator design and characterization
• Hands‑on PIC tape‑out experience with commercial foundries using Cadence, GDSfactory, or other similar code‑based layout tools.
• Experience developing PICs that have reached HVM for IM‑DD or coherent applications
• Hands‑on experience in high-speed electrode or RF design using HFSS, ADS, or similar tools
• Proficient in programming (e.g., Python, MATLAB) for design automation and data analysis with version control experience
• Solid understanding of optical transceiver architectures, system‑level requirements, and link analysis
• Experience in photonic testing and integration at the wafer, die, and package levels
• Working knowledge of coherent optical systems and CPO architectures is a plus
• Familiarity with high-speed analog circuits (e.g., TIAs, modulator drivers) is a plus

• Salary range: $100,000 – $220,000 (role level and salary commensurate with experience and impact)
• Opportunity for rapid advancement

This role will generally be hybrid, based in Carlsbad (Greater San Diego), CA or Taiwan, with flexibility open for discussion.
