Senior Principal Electrical Engineer

Job Description: Lead complete RF/microwave and high-speed mixed-signal hardware architecture for next-generation optical transceivers, evaluation boards, reference platforms, and production test hardware. Design high-speed schematics and PCBAs for 100G/lane, 200G/lane, 400G/lane and beyond interconnects, supporting 800G, 1.6T, 3.2T and future architectures where applicable. Own board-level tradeoffs for signal integrity, power integrity, EMI/EMC, grounding, return path control, isolation, thermal performance, manufacturability, serviceability, cost, reliability, and schedule. Architect and design high-performance instrumentation used for validation, characterization, calibration, automation, manufacturing test, and sustaining support of fiber optic transceiver modules. Select and qualify high-speed, RF, microwave, analog, precision measurement, clocking, DSP, control, sensing, connector, cable, interconnect, and power components. Define PCB stackups, materials, copper weights, dielectric selection, via structures, backdrill strategy, impedance targets, loss budgets, fabrication rules, assembly constraints, and acceptance criteria. Partner with SI/PI, packaging, optics, firmware, software, mechanical, thermal, reliability, manufacturing, supply chain, and operations teams to deliver complete product and test solutions. Lead schematic capture, layout strategy, layout review, RF structure review, BOM review, DFM/DFT review, design verification, bring-up, debug, characterization, and production release. Define digital control interfaces and hardware/firmware interaction
