fun to work in a company where people truly BELIEVE in what they're doing!\nWe're committed to bringing passion and customer focus to the business.\nIf you like wild growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us!\nKey Responsibilities\nPerform electrical, optical, thermal, and timing measurements of optical transceivers and high-speed communication modules.\nDevelop compliance and characterization reports and support NPI from architecture through production readiness, including design reviews, EVT/DVT, and resolution of DFM issues identified through engineering and factory feedback.\nDesign and revise printed circuit board assemblies (PCBAs).\nConduct RF simulations and analyses of high-speed communication links.\nAnalyze and resolve electrical, RF, and optical transceiver issues through hands-on testing and root-cause analysis.\nWork independently and collaborate with global cross-functional teams, including program management, procurement, planning, manufacturing, and suppliers, to support timely builds.\nCreate and maintain engineering documentation, including schematics, drawings, bills of materials (BOMs), and engineering change orders (ECOs).\nApply knowledge of data-center and AI network architectures spanning scale-up within accelerator systems, scale-out between hosts and nodes, and scale-across racks, clusters, data halls, and distributed network fabrics.\nFollow Lumentum engineering, quality, environmental, health, and safety processes.\nRequired Qualifications and Experience\nBachelor’s degree in Electrical Engineering or a related field.\nAt least two years of relevant experience in electrical, RF, high-speed, or optical transceiver design.\nKnowledge of circuit theory, linear systems, feedback systems, integrated circuits, and high-speed RF fundamentals.\nUnderstanding of data-center and AI architectures, including scale-up, scale-out, and scale-across networking, and how optical transceivers support high-speed interconnects and affect link budgets, bandwidth, latency, signal integrity, power, thermal management, reliability, and system performance.\nFamiliarity with Ethernet, InfiniBand, PCIe, or comparable high-speed interconnect technologies.\nStrong hands-on measurement skills, with the ability to analyze complex problems, identify root causes, and drive effective solutions.\nExperience with electronic design, product development cycles, ECAD, and system modeling tools.\nAbility to work effectively in a collaborative, cross-functional, international environment.\nProfessional fluency in written and spoken English.\nPreferred Qualifications and Skills\nAdvanced degree (Master’s or Ph.D.) in Electrical Engineering, Electronics, Photonics, RF Engineering, or a related discipline.\nRF design and electromagnetic modeling experience using tools such as CST or HFSS.\nKnowledge of embedded and AI computing architectures, including microprocessors, GPUs, TPUs, HBM, NICs, DPUs, switching fabrics, real-time control firmware, and their interconnects.\nBackground in designing or testing optical transceivers, optoelectronic modules, or high-speed communication systems.\nPractical exposure to manufacturing, DFM, supplier engagement, or new product introduction.\nWe are an equal opportunity employer and value diversity at our company.\nWe do not discriminate on the basis of race, religion, color, national origin, sex, gender, gender expression, sexual orientation, age, marital status, veteran status, or disability
