Senior Principal System Architect(Rack level)

About the Position

We're seeking a Senior Principal System Architect (Rack level) to join our team at Renesas in Bengaluru, India. This role is pivotal in leading the design of high-speed backplane topologies and optimizing rack-level communication paths for our AI training cluster.

Responsibilities

• System & Topology Architecture

  • Lead the structural, electrical, and logical design of the UALink switch chassis.
  • Define high-speed backplane topologies, cabled scale-up fabrics, and multi-tier switch hierarchies.
  • Partner with electrical and SI/PI engineering teams to define parameters for ultra-high-speed SerDes routing across PCBs, flyover cables, and optical components, minimizing bit error rates (BER).
  • Architect rack-level and row-level topologies that optimize collective communication paths (e.g., All-Reduce, All-to-All) for tens of thousands of interconnected GPUs.

• Platform Management & Software Infrastructure

  • Architect the end-to-end system management plane. Define how Baseboard Management Controllers (BMCs) monitor, configure, and provision the switch using OpenBMC, Redfish, and PLDM over MCTP.
  • Establish platform-level boot sequencing, multi-rail power sequencing, and secure multi-node firmware update orchestration.
  • Define the hardware security lifecycle, including Platform Firmware Resiliency (NIST SP 800-193), secure enclave integration, and Component Attestation (SPDM).

• Advanced RAS & Infrastructure Integration

  • Architect system-level Reliability, Availability, and Serviceability (RAS) strategies. Define how the platform isolates hardware faults, routes around failed links, handles hot-swapping of fans, power supplies, and switch blades without dropping the AI training cluster.
  • Establish dynamic power management and telemetry frameworks to balance the massive transient power draws of next-generation AI workloads against rack-level cooling limits.

Requirements

• Education & Experience

  • Master’s or Ph.D. in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
  • 20+ years of architectural experience in high-performance server platforms, hyper-scale network switches, or data center infrastructure.

• Technical Skill Set

  • Expert knowledge of high-speed platform fabrics and standards (UALink, NVLink, OAM/UBB, PCIe Gen6/Gen7, CXL, or Ultra Ethernet).
  • Deep expertise in industry-standard management architectures, including Redfish, IPMI, MCTP, SPDM, and OpenBMC.
  • Thorough understanding of OS/VMM kernels, device drivers, and platform initialization frameworks (UEFI, ACPI).
  • Comprehensive grasp of modern rack architectures (e.g., OCP ORv3), liquid cooling management, and high-density 48V/54V power delivery.

Preferred Attributes

• Proven track record of delivering a high-volume, multi-million-gate switching or compute platform successfully into top-tier hyper-scale cloud providers (AWS, Azure, GCP, Meta).
• Active committee leadership or direct specification contributions within the UALink Consortium, Ultra Ethernet Consortium (UEC), or Open Compute Project (OCP).
• Experience architecting systems designed for ultra-high-density accelerator form factors (such as Nvidia Blackwell/Vera Rubin grids or AMD Instinct platforms).

We Offer

• Competitive salary
• Opportunity to work in a global, innovative, and entrepreneurial environment
• Be part of a team shaping a safer, healthier, greener, and smarter future
