R&D Engineer

Job description

It's fun to work in a company where people truly BELIEVE in what they're doing! We're committed to bringing passion and customer focus to the business. If you like wild growth and working with happy, enthusiastic over-achievers, you'll enjoy your career with us! Key Responsibilities Perform electrical, optical, thermal, and timing measurements of optical transceivers and high-speed communication modules. Develop 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. Design and revise printed circuit board assemblies (PCBAs). Conduct RF simulations and analyses of high-speed communication links. Analyze and resolve electrical, RF, and optical transceiver issues through hands-on testing and root-cause analysis. Work independently and collaborate with global cross-functional teams, including program management, procurement, planning, manufacturing, and suppliers, to support timely builds. Create and maintain engineering documentation, including schematics, drawings, bills of materials (BOMs), and engineering change orders (ECOs). Apply 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. Follow Lumentum engineering, quality, environmental, health, and safety processes. Required Qualifications and Experience Bachelor’s degree in Electrical Engineering or a related field. At least two years of relevant experience in electrical, RF, high-speed, or optical transceiver design. Knowledge of circuit theory, linear systems, feedback systems, integrated circuits, and high-speed RF fundamentals. Understanding 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. Familiarity with Ethernet, InfiniBand, PCIe, or comparable high-speed interconnect technologies. Strong hands-on measurement skills, with the ability to analyze complex problems, identify root causes, and drive effective solutions. Experience with electronic design, product development cycles, ECAD, and system modeling tools. Ability to work effectively in a collaborative, cross-functional, international environment. Professional fluency in written and spoken English. Preferred Qualifications and Skills Advanced degree (Master’s or Ph.D.) in Electrical Engineering, Electronics, Photonics, RF Engineering, or a related discipline. RF design and electromagnetic modeling experience using tools such as CST or HFSS. Knowledge of embedded and AI computing architectures, including microprocessors, GPUs, TPUs, HBM, NICs, DPUs, switching fabrics, real-time control firmware, and their interconnects. Background in designing or testing optical transceivers, optoelectronic modules, or high-speed communication systems. Practical exposure to manufacturing, DFM, supplier engagement, or new product introduction. We are an equal opportunity employer and value diversity at our company.
