Responsibilities

  • Define and architect optical transceiver modules (1.6T and beyond) aligned with product-level requirements.
  • Design high-speed PCB schematics including power, control, and signal interfaces for optical modules.
  • Guide layout engineers to complete PCB layout that meets mechanical, signal integrity, thermal, and manufacturing constraints.
  • Collaborate across disciplines to ensure successful integration of optical, electrical, and mechanical systems.
  • Lead technical validation, bring-up, and performance optimization of optical transceivers.
  • Support design validation, qualification, and root-cause analysis during development and production ramp.
  • Stay current with and implement relevant industry standards (IEEE, MSA, CMIS, etc.).
  • Contribute to automation of transceiver performance testing using Python, C++, or LabVIEW.
  • B.Tech (or equivalent) in Electrical Engineering or related field.
  • 10+ years of experience in optical transceiver design, fiber optics, RF modulation, and networking systems.
  • Hands-on experience with: PCB schematic design and layout review for optical modules.
  • High-speed opto-electrical system design, including DSPs, power rails, and microcontroller interfaces.
  • MSA and IEEE standards for optical transceivers (e.g., QSFP, OSFP, CMIS).
  • Testing transceiver performance: TDECQ, receiver sensitivity, stressed eye measurements.
  • DSP configuration and FIR equalization optimization for PAM4/NRZ signaling.
  • Software scripting skills for automation using Python, C++, or LabVIEW.
  • Strong verbal and written communication skills, capable of interfacing across technical and managerial levels.

Requirements
