Job description

Title: Principal Systems Architect (Hardware & Software) Location: San Jose, CA Duration: Full-Time/Perm Role Summary As a Lead System Architect at Client, you will define the end-to-end architecture bridging silicon (ASIC/SoC), board-level hardware platforms, and low-level system software/firmware. Leveraging your deep expertise in the server and infrastructure industry, you will translate customer requirements into detailed technical specifications. This high-impact role requires navigating complex hardware/software tradeoffs while collaborating closely with Client's engineering teams, customers, standards organizations and ecosystem partners. Key Responsibilities 1. Architectural Definition & Detailed Specification • Own and author comprehensive, unambiguous system architecture specifications, micro-architectural specs, and/or platform requirement documents. • Define rigorous system-level hardware/software partition boundaries and map out register-level interfaces for hardware blocks and low-level software stacks. • Drive micro-architecture specifications for high-security, AI-driven SoCs, including on-chip interconnects (AXI/AHB), memory hierarchies, and standard I/O interfaces (PCIe, Ethernet, SPI, eSPI, I3C, LTPI). 2. Customer Interfacing & Ecosystem Engagement • Serve as a primary technical point of contact for enterprise and hyperscaler customers to gather, analyze, and scope their next-generation platform security needs. • Present Client's system architecture roadmap and technical whitepapers to strategic customers, steering-level partners, and standards committees. • Align Client's technology with modern server deployment topologies and open-source standards (such as OCP DC-SCM / DC-SCI). 3. Server Infrastructure & Board-Level Integration • Architect platform-level designs optimized for enterprise server motherboards, baseboard management systems, and cloud data center environments. • Guide hardware and SI/PI engineers on signal integrity, power delivery networks, and thermal/mechanical constraints for modular server building blocks. 4. Software, Firmware & Security Stack Partitioning • Specify secure platform boot flows, Root-of-Trust (RoT) architecture, and Platform Firmware Resiliency (PFR) frameworks. • Collaborate with firmware teams to define interfaces for BMC stacks (OpenBMC), Linux kernels, device drivers, and platform management protocols (MCTP, PLDM, Redfish). Required Qualifications • Experience: 15+ years of dedicated system architecture experience spanning SoC design, board development, and software stacks. • Industry Focus: Proven track record of engineering and architectural success within the server, data center, or enterprise infrastructure industry. • Specification Ownership: Demonstrated ability to independently produce and maintain highly detailed, production-grade technical specifications. • Customer Facing: Excellent communication and presentation skills, with comfort interfacing directly with sophisticated enterprise customers and technical stakeholders. • Education: B.S., M.S., or Ph.D. in Electrical Engineering, Computer Engineering, Computer Science, or a related field. • Technical Breadth: • Silicon: Deep knowledge of SoC design flows, interconnects, and interfaces (PCIe, Ethernet, DRAM, USB). • Board-Level: Hands-on experience with hardware platform design, schematic capture, and lab bring-up tools (oscilloscopes, logic analyzers). • Software: Clear understanding of embedded firmware, RTOS, Linux device drivers, and low-level C/C++ programming. Preferred Qualifications • Active participation in open infrastructure communities like the Open Compute Project (OCP). • Deep understanding of hardware security concepts (cryptographic accelerators, HSM, TPM, Side-Channel attack mitigations). • Experience with BMC firmware architecture (OpenBMC) and server management interfaces (MCTP, NVMe-MI, LTPI). Qualifications • Experience & Education: 15+ years of hardware engineering experience with a leadership track record in server, data center, or semiconductor ecosystems. B.S. or M.S. in Electrical Engineering (EE). • Production Track Record: Proven history of taking complex board designs to high-volume production with excellent yields and resolving field RMA issues. • Hands-on Technical Mastery: Deep, continuous experience with circuit design, schematic capture, laboratory equipment, and platform troubleshooting. • DC-SCM & Ecosystem Expertise: Strong knowledge of OCP DC-SCM standard solutions (DC-SCI interface, form factors) and a solid network across hyperscaler and OEM partners. • Supply Chain Agility: Demonstrated capability to execute rapid hardware redesigns, footprint compatibility strategies, and alternative component sourcing. • Tool & Interface Proficiency: Expert familiarity with Cadence OrCAD/Allegro and server interfaces (PCIe, USB, I2C, SMBus, SPI, UART, USB, MCTP, eSPI, LTPI). • Architecture & Software Knowledge: Solid understanding of modern CPU/GPU architectures and the Linux environment (including Python or Bash scripting). • Communication: Exceptional verbal and written communication skills to articulate hardware-anchored security and supply chain strategy to enterprise stakeholders.
