Senior Optical Transceiver R&D Engineer
Core
Design, characterize, and qualify advanced optical transceiver reference designs (QSFP/OSFP) for AI/datacom and hyperscale computing applications.
Role type
Senior IC optical transceiver R&D engineer
Builds
High-performance optical transceiver modules (IMDD/coherent) for 1.6T+ systems
Domain
Integrated photonics / Datacom / Telecom
Required skills
High-speed optical transceiver testing, QSFP/OSFP form factors, PAM4 modulation, BER/OSNR/TDECQ analysis, lab equipment operation (oscilloscope, DCA, BERT, OSA, VNA), circuit design & characterization, signal integrity, debugging, root-cause analysis
Preferred skills
Datacom/Telecom transceiver design experience, firmware/DSP collaboration, failure analysis, design improvement recommendations
Technologies
TFLN (thin-film lithium niobate), QSFP, OSFP, IMDD, coherent optics
Responsibilities
Define and execute test plans for optical transceivers, characterize transceiver performance (BER, eye diagrams, SNR, OSNR, TDECQ, OER, OMA, receiver sensitivity, latency), validate TFLN modulator-based transceivers across electrical/optical/thermal domains, bring up and debug QSFP/OSFP transceiver modules, collaborate with firmware and DSP teams to tune system performance, support compliance testing (IEEE, OIF, CMIS), analyze failures and drive root-cause resolution
Seniority
Senior, hands-on IC
