Senior Principal Engineer, Hardware Application Engineering - Board & System Design

Job Title

Senior Principal Engineer, Hardware Application Engineering - Board & System Design

Role Summary

Senior individual contributor responsible for guiding customer hardware design-in and reference platforms for Marvell Ethernet Switch and UALink silicon. Focus areas include board architecture, PCB stack-up and material selection, power architecture, thermal and mechanical integration, SI/PI, and ensuring designs are manufacturable and production-ready.

Work within Marvell's U.S. Customer Solutions Group, partnering with customers, silicon, packaging, and internal hardware teams to deliver reference designs and productization support.

Experience Level

Senior - typically 15+ years of experience in hardware design; at least 7 years focused on board and system design for high-speed SerDes platforms.

Responsibilities

Provide senior technical leadership across customer engagements, reference designs, and productization for high-speed switch and AI fabric platforms.

• Advise customers from early architecture through production ramp on platforms using Marvell switches and UALink silicon.
• Review customer schematics, PCB stack-ups, materials, and system architecture; identify risks and recommend mitigations.
• Define, develop, and support Marvell reference and evaluation platforms; provide schematic, layout guidance, and hands-on bring-up.
• Drive PCB stack-up strategy and material selection (low-loss laminates, copper roughness, glass weave, via construction) to meet high-speed and cost targets.
• Design and review power delivery architectures (PDN, sequencing, decoupling) for high-current ASICs.
• Advise on thermal design, mechanical integration, and cooling strategies (air, liquid, immersion) for reliability and performance.
• Provide SI/PI guidance, review customer simulations, and perform targeted simulations when required.
• Lead hardware bring-up support, lab debug, root-cause analysis, and production issue resolution at customer sites and ODM/CM labs.
• Develop and deliver technical training for customers and internal teams; represent Marvell in technical briefings and industry forums.
• Capture field feedback to influence silicon I/O, packaging, and platform roadmaps.

Requirements

Must-have skills and experience:

• 15+ years in hardware design, development, and validation of high-speed networking or compute systems.
• 7+ years specifically in board and system design for high-speed platforms (25G NRZ through 112G/224G PAM4 and beyond).
• Proven full-lifecycle ownership of complex high-speed boards: architecture, schematic, layout guidance, and bring-up.
• Expertise in PCB stack-up design and material selection for high-layer-count, high-speed boards.
• Deep experience with power architecture for high-current ASICs, PDN design, sequencing, decoupling, and tolerance analysis.
• Strong background in thermal design and mechanical integration for high-power networking and AI systems.
• Working knowledge of SI/PI principles and hands-on lab debug using industry-standard equipment.
• Experience with high-speed interfaces (Ethernet, PCIe, DDR, advanced SerDes) and design for reliability, manufacturability, and testability.
• Customer-facing experience supporting complex technical engagements and delivering technical training; excellent communication skills.
• Eligibility to access export-controlled technology may be required; non-U.S. applicants may be subject to export license review.

Nice-to-have:

• Direct experience with Ethernet switch platforms and emerging open AI fabric standards.
• Experience targeting megascale data center deployments and ODM/CM manufacturing flows (DFM/DFT, qualification, reliability testing).
• Familiarity with advanced cooling (liquid, immersion) and EDA tools (Cadence Allegro/Sigrity, Mentor/Siemens Xpedition/HyperLynx).
• Proven ability to influence silicon and platform roadmaps from customer and field insights.

Education Requirements

PhD, Master's, or Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field.
