Senior Principal Electrical Engineer

Primary Duties & Responsibilities


* 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 requirements for CPLDs, FPGAs, microcontrollers, DSPs, drivers, TIAs, modulators, lasers, sensors, ADCs, DACs, and power controllers.


* Develop validation plans, test methods, calibration approaches, correlation methods, guardband strategies, and production screening methods for high-volume test environments.


* Perform hands-on lab measurements and debug using oscilloscopes, VNAs, spectrum analyzers, BERTs, pattern generators, optical power meters, optical spectrum analyzers, thermal chambers, power supplies, SMUs, and automated test systems.


* Lead design reviews, risk reviews, failure analysis, root cause analysis, corrective actions, and lessons-learned across programs.


* Mentor senior and mid-level engineers; establish hardware design best practices, checklists, libraries, reuse blocks, and review criteria.


* Engage with suppliers and technical partners on advanced components, connectors, PCB materials, laminates, cable assemblies, sockets, fixtures, and precision measurement technologies.


* Support critical customer discussions, roadmap evaluations, architecture tradeoffs, and executive-level technical reviews as required.
