Senior Principal Engineer, Hardware Application Engineering — Board & System Design - Santa Clara, CA, United States
Originally posted 3 June 2026 by the employer. Relisted by the employer on 22 October 2026.
Guide customer hardware design-in and reference platforms for Marvell Ethernet switch and UALink silicon spanning 112G, 224G, and 448G SerDes architectures.
About the role
As Senior Principal Engineer for Board & System Hardware Design, you will serve as the technical authority guiding customer hardware design-in on Marvell's Ethernet Switch and UALink platforms, bridging internal silicon teams, hardware engineering, and customer deployments. You will review and shape board architectures, PCB stack-ups, power delivery networks, and thermal solutions spanning 112G and 224G PAM4 SerDes systems toward 448G architectures.
What you'll do
- Serve as technical advisor to customer hardware teams designing platforms around Marvell's Ethernet switches and UALink silicon from early architecture through production ramp. - Lead design-in reviews of customer schematics, PCB stack-ups, power delivery networks, and system architectures to identify technical risks. - Define, develop, and support reference designs and evaluation platforms for Marvell silicon across architecture, schematic capture, layout guidance, and lab bring-up. - Drive PCB stack-up strategy and material selection, including low-loss laminates, copper roughness, glass weave, and via construction. - Guide power delivery architecture (PDN design, multi-rail sequencing, decoupling strategy, and tolerance analysis) and thermal/mechanical cooling strategies (air, liquid, immersion) for high-current ASICs. - Provide signal integrity and power integrity guidance by evaluating customer SI/PI simulations and executing targeted simulations when required.
What you'll need
- PhD, Master's, or Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field. - 15+ years of experience in hardware design, development, and validation of high-speed networking or compute systems. - 7+ years of dedicated experience in board and system design for high-speed platforms involving modern SerDes (25G NRZ through 112G/224G PAM4). - Full-lifecycle ownership of complex high-speed boards across architecture, schematic capture, layout guidance, and lab bring-up. - Demonstrated experience defining and delivering reference designs enabling customer or internal platform adoption. - Deep expertise in PCB stack-up design, material selection for high-layer-count boards, and power delivery architecture (PDN, sequencing, decoupling, tolerance analysis) for high-current ASICs. - Hands-on experience with hardware bring-up, lab debug, SI/PI simulation review, and high-speed interfaces including Ethernet, PCIe, and DDR.
Nice to have
- Direct experience with Ethernet switch platforms or emerging open AI fabric standards and architectures. - Experience designing or reviewing platforms targeting megascale data center deployments. - Background in reference platform design and customer enablement for silicon-based solutions. - Familiarity with ODM/CM manufacturing flows, including DFM/DFT, qualification, and reliability testing. - Experience with advanced cooling approaches, including liquid and immersion cooling, for high-power platforms. - EDA tool fluency in Cadence (Allegro/Sigrity) or Mentor/Siemens (Xpedition/HyperLynx) ecosystems.
