We are seeking a talented Optical HW Engineer to join our energetic team, contributing to the design and development of cutting-edge optical coherent transceiver plug/transponder line card, plus integration and oDVT (optical design verification test).
You will own optical design and integration at system and product level: optical architecture, how the product is verified, manufacturing handoff, and technical authority on optical design and DVT. You will turn product requirements into optical architecture, design rules, and oDVT coverage; lead closure of performance gaps across optics / DSP / firmware / card; and be accountable for optical quality at release.

Responsibilities
Own optical design architecture for coherent transceivers and transponder line cards: optical path, component/module strategy, schematic/design rules for optics, and approval of design updates.
Lead design reviews of schematic, layout, mechanical fiber, thermal, and SI as they affect optical performance; approve optical design for the product.
Decide tradeoffs among PIC, analog ASIC, DSP,
pluggable vs embedded, and line-card optics; negotiate with architecture, ASIC, and PIC teams.
Set oDVT scope, pass/fail criteria, and coverage vs product requirements, impairments, environment, and MSA/reference (OIF, OpenZR+, OpenROADM, ITU-T as applicable).
Integrate optical modules into coherent transceivers and transponder line cards, ensuring optical performance.
Compare results to spec and MSA/reference; 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, compliance) in the optical design; not added after oDVT, and not only a lab prototype.
Define calibration architecture and the manufacturing optical test strategy (yield, test time, DVT-to-production correlation).
Approve test plans, procedures, and release reports; sign optical design and o
