The role involves deep technical work across electrical/optical validation, automation, and interoperability testing. Ideal candidates will have hands-on experience with 400G/800G optics, 100G-PAM4 per lane signaling, and industry standards like CMIS and SFF-8636. A strong understanding of optical module functional blocks and host switch configuration, such as Broadcom Tomahawk-based platforms, is also required.KEY RESPONSIBILITIES:Develop and execute transceiver qualification plans, including electrical, optical, and system-level validationPerform compliance and performance testing for 100G/lane PAM4 transceivers (400G/800G)Validate optical transceiver block functionality, including CDR, DSP, modulator driver, TIA, EML/DML/VCSEL optics. Loopback, DDM/DOM monitoring, FEC performance under stressConfigure and debug host-side switches, for example, Broadcom Tomahawk (TH4/TH5)-based platforms, using SDK/CLIVerify host-module interoperability, link training, lane tuning, and signal integrity performanceValidate compliance to MSA CMIS (v4.0+) and SFF-8636, including diagnostics, state machines, and memory mapsAutomate testing and reporting using PythonConduct signal integrity analysis: eye mask testing, VEC, TDECQ, COM, CTLE/FFE/DFE tuningPerform thermal cycling, power stress, voltage margining, and environmental reliability testingAnalyze results and drive root cause investigations with R&D and supplier teamsSupport vendor qualification, platform-level bring-up, and firmware validationLead test infrastructure improvements and collaborate with cross-functional teams on release readinessPREFERRED EXPERIENCE:5+ years of experience in the optical networking or high-speed data communications industryStrong hands-on experience with 100G/lane optical transceivers, QSFP-DD/OSFP/QSFP112, 400G/800G/1.6TIn-depth knowledge of optical transceiver functional blocks and how they impact system performanceFamiliar with host switch configuration and testing, ideally with Broadcom Tomahawk based switchesExperience with: CMIS, SFF-8636, I2C communication, memory map register control. Lab instruments: DCA-X, BERT, real-time scope, OSA, power metersSkilled in Python scripting for automation and data processingStrong understanding of SerDes tuning eye diagrams, jitter, and electrical complianceExperience working across both module and system (host) sides of the linkExperience with: AOC/DAC, pluggable transceivers, and high-volume test setups. Host board electrical compliance testing. CMIS extensions, vendor-specific diagnostic fields. Optical protocol test tools (Ixia, Spirent)Knowledge of thermal and airflow design for transceiver deployment in data center switchesACADEMIC CREDENTIALS:B.S. or M.S. in Optical Engineering, Electrical Engineering, Physics, or relatedLOCATION: Santa Clara, California (Onsite)#LI-CS1Benefits offered are described: AMD benefits at a glance.AMD does not accept unsolicited resumes from headhunters, recruitment agencies, or fee-based recruitment services.
