SoC Architect

TYLsemi • San Jose, CA

57d • $175,000 - $350,000

About The Position

We are seeking a SoC Architect to define and drive the architecture of next-generation XPUs for AI Infrastructure. This role involves end-to-end ownership of system and SoC architecture, from concept to silicon, with a strong emphasis on scalability, performance, interconnects, and system-level optimization.

Requirements

• Bachelor’s/Master’s/PhD in Electrical Engineering, Computer Engineering, or related field
• 18+ years of experience in SoC or system architecture
• Proven track record of architecting complex SoCs for AI, HPC, or Networking
• Deep understanding of: System-level design and trade-offs, High-speed IO protocols (UCIe, PCIe, Ethernet), Data movement and interconnect design
• Experience with performance modeling and architectural simulation
• Strong cross-functional collaboration skills

Nice To Haves

• Experience with memory architectures (DDR, HBM, cache hierarchies)
• Familiarity with chiplet architectures and advanced packaging (2.5D/3D)
• Knowledge of coherency protocols (CXL, CHI.)
• Experience with power/performance optimization at system level
• Exposure to software-hardware co-design

Responsibilities

• Define system architecture for complex SoCs, including compute, interconnect, memory, and IO subsystems
• Drive architecture for scalable and modular designs, including chiplet-based systems (UCIe)
• Architect high-performance data movement across: Compute engines (ARM/RISC-V/ML/MAC), Memory subsystems (DDR/LPDDR/HBM), IO interfaces (PCIe/UCIe/CXL/UALink/ESUN)
• Collaborate with design and DV teams to ensure architectural feasibility and efficient implementation
• Develop performance models and simulations to validate architecture choices
• Drive trade-offs across: Performance, Power, Area and Cost
• Define system-level verification and validation strategies
• Work closely with customers and software teams to align architecture with real-world workloads
• Influence long-term roadmap and technology direction
