Job Summary We are seeking an experienced System Architect for Networking Products to lead architecture concept work during the early design phase. This role focuses on translating customer use cases and technical trends into viable, scalable networking architectures to support RFQ/RFI and new business engagements. You will collaborate closely with stakeholders (e.g., CTO, BU, Marketing) to define system-level strategy, high-level configurations, and functional requirements for next-generation Ethernet switch platforms.

Requirements

Strong knowledge in networking system architectures (TOR, aggregation, core switches).
Ability to research and explore unfamiliar technologies and concepts with an eye towards feasibility.
Familiar with Networking ASIC topologies (e.g., Broadcom Tomahawk/Trident/Monaco, Marvell Prestera), and their implications on I/O mapping, cooling, and power.
Familiarity with PCB board materials and construction techniques. Specifically, an understanding of trade-offs and optimizations around insertion loss, via construction, stack-ups and sizing of power planes and shapes.
High-level understanding of voltage regulators related to types of VR architectures, trade-offs, efficiency, thermals, and critical VR components.
Ability to use industry standard ECAD tools to review layouts and schematics is required.
Strategic thinker with system-level ownership mindset
Familiarity with networking system-level architecture
Strong leadership and cross-functional coordination skills
Comfortable working in fast-paced, cross-functional, global teams
Proactive, self-driven, with high adaptability
Clear technical communicator, able to present trade-offs and justify proposals
Capable of NRE estimation and abstract requirement hardening
Fluent in English; able to work with global teams and customers
Bachelor’s degree in Electrical, Computer Engineering, or a related field (Master’s preferred)
15+ years of experience in data center or networking system architecture, including switch/router design. (Server design is a plus)

Nice To Haves

Ability to manipulate existing ECAD layouts and schematic databases for purposes of architectural planning and assessment preferred.
Experience coding, sizing, and planning FPGAs, preferred.
Fluency in the mechanical, firmware and software domain. Specifically, an understanding of basics nomenclature, concepts and tools used by your architectural teammates.
Fluency in the thermal domain. Specifically, an understanding of component cooling techniques, when components require cooling and what information your thermal engineering teammate needs during concept assessment.

Responsibilities

Lead system-level architecture planning for Networking platforms, including product configuration definition, functional partitioning, and mechanical/thermal/power/cooling feasibility alignment.
Drive the definition of system requirements, interface specifications, and early configuration options (e.g., TOR, aggregation, core switch).
Conduct architectural trade-off analysis balancing performance, cost, power, scalability, and manufacturability.
Collaborate with EE, thermal, mechanical, BMC, and firmware architects to form a complete product-level concept package.
Work with Architecture and BU teams to evaluate RFQ/RFI requirements and generate competitive architecture proposals.
Define and propose system topologies, mechanical footprints, airflow design, I/O mappings, and cabling options.
Interface with customers and internal stakeholders to align design intent and value proposition during the concept phase.
Present and document concept proposals that include block diagrams, design strategy, trade-off summary, and risk evaluation.
Stay up to date with Ethernet switch ASIC trends, switch software/SONiC ecosystems, and modular platform strategies.
Evaluate and integrate technology enablers such as PCIe Gen5/6, 112G PAM4 SerDes, high-efficiency power stages, and new materials.
Participate in roadmap planning with BU/CTO to ensure platform reusability and alignment with future-generation technologies.
Define how electrical, mechanical, thermal, and firmware domains interact to support functional and performance goals.
Coordinate platform-level integration strategies including MB placement, airflow optimization, and system serviceability.
Align system-level DFM/EMC/thermal reliability requirements in early phase and guide downstream teams with clear targets.
Lead the creation of architecture decks, system requirements, platform-level block diagrams, and BoM-level feasibility plans.
Drive internal and customer-facing design reviews for architecture alignment and requirement sign-off.
Maintain issue-tracking and lessons-learned documentation to improve future concept efficiency.
