About the role

Lead and mentor a team in the design and development of next-generation optical-transceiver interconnect solutions for data center and AI applications, coordinating system-level modeling, verification, and cross-functional collaboration to achieve high bandwidth, efficiency, and reliability.

Responsibilities

  • Lead and mentor a team in the design of optical transceiver products from concept through implementation.
  • Define system-level specifications and oversee the development of comprehensive end-to-end optical system models, including DSP, drivers, TIA, lasers, Mach-Zehnder modulators (MZMs), and photodetectors.
  • Guide and review signal integrity analysis and the implementation and simulation of digital equalization techniques such as FFE, DFE, MLSD, and pre-emphasis for signal integrity optimization.
  • Set and drive the definition of verification testing requirements for both transceivers and components.
  • Oversee analysis of the impact of impairments such as noise, crosstalk, non-linearity, and reflections on system performance.
  • Support the team in conducting both numerical and analytical simulations to assess optical system behavior under realistic operating conditions.
  • Ensure simulation models are correlated with experimental data at module and component levels.

Qualifications

  • Demonstrated leadership experience in transceiver design and high-speed optical communication systems and components.
  • Familiarity with direct-detection and coherent optical communication architectures.
  • Expertise in modeling optoelectronic components (e.g., lasers, modulators, photodiodes, DAC, ADC, driver, TIA) using tools such as VPIphotonics, MATLAB, or Python.
  • Familiarity with advanced DSP techniques, such as linear and decision-feedback equalization (FFE/DFE).
  • Knowledge of modeling on common impairments in high-speed optical links.
  • Hands-on experience with high-speed optical component measurements using oscilloscopes, spectrum analyzers, and other relevant equipment.
  • Strong communication and team leadership skills.
  • Willingness to travel (~20% of the time).

Benefits

  • Competitive salary commensurate with experience
  • Comprehensive benefits package, including health insurance
  • Professional development and certification opportunities
  • Access to cutting-edge optical/photonics test environments and tools
  • A collaborative, cross-functional team dedicated to solving some of the hardest challenges in photonics
  • Equal opportunity employer: All qualified applicants will receive consideration without regard to race, color, religion, gender, identity, orientation, veteran status, disability, or any other legally protected status
