Responsibilities
• Own hardware development across the full product lifecycle, including concept definition, architecture, detailed design, prototype bring-up, verification, qualification, production introduction, sustaining engineering, and field issue resolution.
• Design and develop high-speed analog and mixed-signal circuits, including laser drivers, modulator drivers, transimpedance amplifiers (TIAs), bias control circuits, clocking and PLL solutions, ADC/DAC interfaces, and low-noise power delivery systems.
• Develop high-speed PCB designs for 112G/224G PAM4 and coherent optical applications, including stack-up definition,



impedance control, length matching, via and back-drill strategies, and connector selection.
• Apply expertise in analog and mixed-signal circuit design, including amplifiers, filters, data converters, PLLs, low-noise design techniques, and power management architectures.
• Utilize knowledge of high-speed serial interfaces, such as 56G/112G/224G PAM4, CEI, and OIF standards, as well as an understanding of coherent modulation concepts including QPSK, 16QAM, phase recovery, and frequency recovery.
• Apply RF and microwave fundamentals, including S-parameters, matching networks, noise figure, linearity, signal integrity, and clock distribution principles.
• Drive design-for-manufacturability (DFM), design-for-assembly (DFA), design-for-testability (DFT), reliability, serviceability, and cost optimization initiatives throughout the product lifecycle.
• Collaborate with signal integrity and pow
