Senior PIC Designer (Switches)

Responsibilities

• Design PICs including active switching elements, modulators, routing networks, and polarization management structures
• Perform optical/electrical simulations and modeling of photonic devices, switching behavior, and control performance
• Develop calibration methods for tuning, monitor photodiodes, crosstalk mitigation, and automated control flows
• Collaborate with electronics and driver teams on DACs, drivers, and electro-photonic integration
• Support tapeouts including layout reviews, DRC/LVS, DFM, and foundry coordination
• Support silicon validation, lab characterization, and simulation-to-hardware correlation

Requirements

• Ph.D. or M.S. in Electrical Engineering, Physics, Photonics, or related field
• 5+ years of experience in silicon photonics or integrated photonic design
• Strong experience with active photonic devices, switching architectures, and electro-optic tuning
• Experience with electronic interfaces, drivers, DACs, and photonic control systems
• Experience with simulation tools such as ADS, VPIphotonics, Lumerical, INTERCONNECT, Cadence, or KLayout
• Hands-on experience supporting PIC development through tapeout and validation
• Familiarity with calibration methods, thermal effects, and fabrication variability
