Platform Architect
San Jose, CA
Full-time
Onsite
Senior Level, Lead/Staff
8+ years expEtched is building the world’s first AI inference system purpose-built for transformers, delivering over 10x higher performance and lower costs. As a Platform Architect, you will lead the definition and realization of AI server platform architecture, collaborating with cross-functional teams to design scalable systems for high-performance workloads.

Responsibilities
Architect the end-to-end hardware system stack, including server-level components, rack-scale systems, and multi-rack POD designs optimized for AI and high-performance workloads
Design and implement advanced PCIe Gen5/Gen6 topologies: root complex architecture, retimer placement, switch hierarchy, and accelerator fan-out strategies
Define scalable BMC architecture and platform management features across fleet deployments, including telemetry pipelines, orchestration hooks, and API integrations (e.g., Redfish, IPMI)
Specify and lead the implementation of chip-to-chip interconnects such as NVLink, UCIe, and other emerging high-bandwidth, low-latency fabrics
Develop integration strategies for power distribution, control planes, cooling systems (air and liquid), and shared interconnect fabrics at the rack level
Own the networking architecture across servers and racks, including 400G/800G Ethernet, leaf-spine switching, NIC-to-ToR planning, and cross-rack topology
Specify power delivery systems for high-density, multi-kilowatt platforms: VRM selection, power trees, sequencing, and protection logic
Guide system design decisions with awareness of mechanical and thermal constraints to ensure performance, manufacturability, and serviceability
Contribute to rack-level management infrastructure: CDU planning, telemetry aggregation, rack controller architecture, and out-of-band control
Support bring-up and validation teams in debugging complex issues at the system, rack, and POD levels
Qualification
Required
8+ years of experience in system or server hardware architecture, ideally in HPC, AI infrastructure, or hyperscale data centers
Deep understanding of PCIe protocols and topologies, including bifurcation, retimer tuning, switch fabrics, and accelerator communication
Experience with rack-level and multi-rack system design, including shared power and networking infrastructure
Strong expertise in BMC systems, control buses, telemetry integration, and orchestration tooling
Familiarity with modern high-speed networking technologies: 400G Ethernet, InfiniBand, CXL fabrics, and NIC-switch integration
Proven background in power architecture for dense compute systems, including power budgeting, sequencing logic, and VRM optimization
Rack-level management infrastructure design experience, including CDU layout, telemetry aggregation, and rack controller implementation
Proven track record of building infrastructure for at-scale deployment, such as automated diagnostics, health monitoring, and fleet orchestration frameworks
Understanding of thermal design principles such as airflow, heatsink selection, and liquid cooling systems
A systems-level perspective with the ability to design scalable, maintainable, and high-performance platforms
Excellent communication skills and experience collaborating with hardware, firmware, validation, and mechanical engineering teams
