About the role

Key responsibilities & impact

Define high-level SoC subsystem architecture for LPU products
Convert LPU product requirements into architectural specifications for uncore, IO, memory, firmware-facing, boot, reset, safety, fault tolerance, diagnostic, and power regulation subsystems
Collaborate intimately with IP teams to develop detailed build documents for PCIe/CXL, NVLink/NVLink-C2C, UCIe, AXI/CHI, NoC fabrics, memory controllers, coherency blocks, MMUs/IOMMUs, boot, reset, and associated SoC infrastructure
Specify subsystem behavior encompassing enumeration, capability discovery, configuration flows, sequence control of memory operations, data consistency, address mapping, interrupt handling, virtualization, error handling, and firmware/software-visible controls
Build or guide functional and architectural models from specifications, using C++, SystemC, Python, or similar languages
Use models to validate architecture intent, subsystem behavior, configuration sequences, and IP interactions before RTL or silicon is available
Drive tradeoffs across bandwidth, latency, power, area, timing, scalability, reliability, security, debuggability, and software usability
Review IP specifications, subsystem architecture documents, model behavior, verification plans, and validation strategies
Collaborate with architecture, IP, firmware, software, RTL, verification, platform, and post-silicon teams to bring architecture decisions to completion

Requirements

What you’ll need

BS, MS, or PhD in Electrical Engineering, Computer Engineering, Computer Science, or equivalent experience
8+ years of proven experience in SoC architecture, subsystem architecture, IO architecture, interconnect architecture, GPU/CPU architecture, accelerator architecture, or high-performance systems
Strong understanding of SoC architecture and uncore subsystem development
Extensive understanding of IO and interconnect cores including PCIe, CXL, NVLink, NVLink-C2C, UCIe, AXI, CHI, or NoC fabrics
Experience working from product requirements to architecture requirements and IP/subsystem specifications
Experience crafting functional models, architectural models, golden models, or C/SystemC models from architecture specifications
Solid grasp of memory ordering, coherency, address translation, interrupts, virtualization, MMUs/IOMMUs, enumeration, configuration, and error management
Solid knowledge of boot, reset, firmware handoff, capability discovery, security, RAS, debug, and power-management architecture
Strong communication abilities and capability to harmonize architecture decisions across IP, firmware, software, verification, and product groups.
