Lead SoC Architect

A semiconductor startup developing next-generation graphics processors is seeking an experienced Lead SoC Architect to own architecture definition and technical direction for advanced compute platforms.

This is a hands-on technical leadership role combining individual contribution with cross-functional engineering leadership. Candidates must be local to the Bay Area and able to work on-site in Sunnyvale.

• Define top-level SoC architecture, subsystem partitioning, interface specifications, and microarchitecture requirements.

• Evaluate tradeoffs across performance, power, area, bandwidth, latency, and scalability.

• Lead performance modeling, workload analysis, and bottleneck identification using C/C++/SystemC or similar tools.

• Define memory hierarchy, NoC/interconnect strategy, cache structures, and coherency architecture.

• Evaluate and integrate third-party IP, including compute, memory, connectivity, multimedia, and security subsystems.

• Collaborate with RTL, verification, physical design, firmware, software, and systems teams throughout development.

• Partner with verification teams on architectural test plans and validation strategies.

• Support silicon bring-up, debugging, performance tuning, and post-silicon optimization.

• Contribute to long-term technology and product roadmaps.

• Bachelor’s or Master’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.

• 10+ years of experience in SoC architecture, ASIC development, or complex semiconductor system design.

• Strong understanding of modern SoC architectures and subsystem integration.

• Expertise in one or more of the following:

  • CPU, GPU, or NPU architectures

  • NoC/interconnect architectures

  • Cache coherency protocols, including CHI, ACE, or CXL

  • High-speed interfaces such as PCIe, UCIe, or Ethernet

  • Memory systems such as DDR5, LPDDR5X, or HBM

  • Power and performance optimization

• Strong knowledge of RTL development and verification methodologies.

• Experience with architecture modeling and performance analysis tools.

• Understanding of firmware/software interaction in complex SoC systems.

• Strong problem-solving, communication, and technical leadership skills.

• Experience with AI accelerators, GPUs, networking, RISC-V, or datacenter SoCs.

• Experience with chiplet-based or multi-die architectures.

• Familiarity with advanced process technologies and package integration.

• Experience with emulation, FPGA prototyping, and system-level validation.

• Knowledge of Linux drivers, runtime software, or system software architecture.

• Prior technical leadership across cross-functional engineering teams.
