High Speed Design Engineer

About the role

We are seeking a Principal High Speed Photonics Design Engineer to lead the development of next generation high speed optoelectronic devices for advanced photonic integrated circuits. This is a hands on senior technical role focused specifically on the design, modeling, optimization, and validation of high speed optical modulators and photodetectors.

Responsibilities

• Lead the design and optimization of high speed III-V and/or SiGe optoelectronic devices, with emphasis on operation at 200 Gb/s and beyond
• Develop active optical components including electro-absorption modulators (EAMs), Mach-Zehnder modulators (MZMs/MZIs), PIN photodetectors, and/or UTC photodetectors
• Model electrical, optical, and RF device behavior including bandwidth, impedance, parasitics, capacitance, traveling-wave effects, and equivalent circuit performance
• Perform high-speed device simulation using tools such as HFSS, CST, ADS, Sentaurus TCAD, Crosslight, or comparable platforms
• Analyze fabricated device measurements and correlate experimental results against simulations to drive subsequent design iterations
• Develop compact and equivalent circuit models suitable for use by PIC designers and system engineers
• Partner with photonic layout and semiconductor process teams to translate device designs into mask layouts and manufacturable structures
• Collaborate with high speed systems, packaging, fabrication, reliability, and test engineering teams to validate device performance in integrated hardware
• Support RF and electro-optical characterization of high speed modulators and photodetectors
• Generate technical design documentation and contribute to patents and technical publications

Requirements

• PhD in Electrical Engineering, Applied Physics, Materials Science, Photonics, or a closely related discipline
• 6+ years of industry experience developing high speed semiconductor optoelectronic devices
• Deep understanding of III-V and/or SiGe semiconductor device physics
• Demonstrated hands on design experience with high speed modulators and/or photodetectors
• Strong experience with devices such as EAMs, MZMs, PIN photodiodes, UTC photodiodes, or closely related high speed active photonic components
• Experience designing devices for optical transceivers, optical interconnects, or high-speed communication systems
• Experience taking device designs through simulation, fabrication, characterization, and design iteration
• Strong knowledge of RF behavior and high speed device characterization
• Experience with high-frequency simulation and device design tools such as HFSS, CST, ADS, Sentaurus TCAD, Crosslight, or equivalent
• Working knowledge of semiconductor fabrication processes and the interaction between device design and process technology
• Ability to work closely with multidisciplinary engineering teams while remaining deeply hands on technically
