Senior Optical Engineer

Responsibilities

• Own optical design of the assigned coherent transceiver: architecture of the optical path, component selection, schematic ownership for optics, and review input to design updates.
• Integrate optical modules into coherent transceivers and transponder line cards, ensuring optical performance.
• Create technical documentation, including test plans, test procedures, and test reports. Capture design issues found in the lab.
• Develop and implement test routines to evaluate key performance for coherent transceivers and transponder line cards.
• Compare results to spec and MSA/reference (OIF, OpenZR+, OpenROADM, ITU-T as applicable); drive closure with DSP, PIC, analog, FW, and hardware.
• Translate oDVT findings into design changes (BOM, schematic, firmware defaults, mechanical fiber routing).
• Apply DFx (test, manufacture, reliability) to the optical design; not only a lab prototype.
• Develop and refine optical calibration sequences with FW/DSP, and support manufacturing optical test (yield, test time, DVT-to-production correlation) for the assigned drop.
• Own test plans, procedures, and reports for the assigned module/card drop; present them in release reviews.
• Run Python (or similar) scripts in the current automation framework; script fixes/updates as required.
• Work with firmware, hardware, and optics teams; collaborate with the cross-functional (XF) team to improve performance.
• Represent optical design, integration, and oDVT in XF meetings for your product drop.
