Principal Opto-Electronics Device Engineer

Design and optimize photonics devices structures for high-speed optical communication applications. Perform optical, electrical, and thermal device simulations using industry-standard tools to predict device performance, optimize designs, and guide layout and fabrication. Collaborate with supplier partners and internal teams to execute tape-outs. Conduct hands-on device characterization in the lab, including DC and high-frequency measurements (S-parameter measurements, eye diagrams), optical power measurements, spectral analysis, and reliability testing. Develop and apply equivalent circuit models and compact models for electro-optic devices to enable co-simulation with electronic driver and transimpedance amplifier (TIA) circuits. Analyze experimental data, correlate with simulation results, and drive iterative design improvements to meet performance targets specifications. Serve as a technical expert in optoelectronic device physics, advising cross-functional teams on device-level trade-offs and their impact on system-level performance. Contribute to intellectual property generation and patent filings. PhD in Electrical Engineering, Physics, Photonics, Optical Engineering, or a related field. Strong foundation in semiconductor physics, including carrier transport, p-n junctions, and photon-matter interactions. Demonstrated experience designing high-speed electro-optic devices operating at GHz frequencies. Proficiency with one or more optical/device simulation packages such as COMSOL Multiphysics, Tidy3D, Ansys Lumerical FDTD/MODE/CHARGE, HFSS, or Sentaurus/Silvaco TCAD. Hands-on experience with optoelectronic device characterization in a lab environment, including high-speed RF measurements and optical test setups. Ability to operate effectively in a multi-disciplinary environment. Excellent communication skills in English, both written and spoken, including the skill to clearly communicate technical results and justify assumptions to diverse technical audiences. Experience with microLEDs, laser or photodetector device design and characterization. Track record of tape-outs in photonic or optoelectronic foundry processes, including PDK development and design-for-manufacturability. Experience with III-V optoelectronic device fabrication and/or silicon photonics platforms. Knowledge of optical packaging, co-packaged optics, optical transceiver architectures, or datacenter interconnect requirements. Experience with driving device concepts from concept to production.
