Optical Design Engineer

What the role needs

• Full-Lifecycle Responsibility: Ownership of PIC product design cycle starting from simulation to layout using Cadence Virtuoso to final GDS tapeout to post-Fab validation.
• Opto-Electronic Integration: Work closely with EIC & module team to co-design highly optimized Opto-Electronic chipsets satisfying system-level specifications.
• Fast-Paced Operation: In line with multiple PIC tapeouts a year, hitting ground running in first 6 months is expected to enable multiple products.
• Next-Gen Mastery: Expect responsibility to design and own small test-chips within a year or two to facilitate next-generation products.
• Rapid Iteration Engine: Many PIC tapeouts per year translates into parallel processing several PIC designs and tracking them through design-tapeout-Fab-validation cycle.
• Minimum Qualifications Bachelors 5 years of related experience, or Masters 3 years of related experience, or PhD 0 years of related experience
• Prior experience in Silicon Photonics circuit modeling, layouts/tapeouts, and fabrication process, including testing and validation.
• Prior experience in photonic device layouts both passive and active (GDS generation using appropriate EDA tools like Cadence, Virtuoso etc.)
• Prior experience with lab measurements, data analysis and automation using tools like Matlab, Labview, Python.
• Prior experience with OE/RF simulation (S-parameters, Co-simulation with electronic driver/TIA, HFSS)
• Prior experience working with silicon photonics foundries
• Prior experience using AI tools for data analysis, testing, and validation
