Rivian is seeking a Principal-level architect to lead the development of next-generation Network-on-Chip (NOC) and DDR memory controller architecture for complex SoCs. This role involves defining architecture across the on-chip data fabric and external memory subsystem, focusing on performance, scalability, and system-level efficiency. The ideal candidate will collaborate closely with various teams to translate product requirements into robust architecture. The position requires deep expertise in SoC interconnects and DDR subsystem architecture.

• BS, MS, or PhD in Electrical Engineering, Computer Engineering, or a related field
• 12+ years of experience in SoC or ASIC architecture with significant ownership of interconnect and memory subsystem design
• Deep expertise in NOC architecture, including topology selection, arbitration, QoS, and performance optimization
• Deep expertise in DDR memory controller architecture and system behavior under real workload conditions
• Strong understanding of high-performance SoC design tradeoffs across performance, power, area, and scalability
• Proven track record of leading cross-functional technical efforts from concept through silicon

• Define end-to-end architecture for NOC and DDR memory controller subsystems in advanced SoCs
• Drive architectural tradeoffs across bandwidth, latency, QoS, and reliability
• Own memory subsystem strategy, including DDR controller architecture and system performance optimization
• Develop architecture specifications for interconnect and memory subsystems
• Lead performance modeling and analysis to evaluate workload behavior and bottlenecks
• Partner with system architects to align subsystem architecture with product requirements
• Review microarchitecture proposals to ensure consistency with system goals
• Drive debug and root-cause analysis for architecture-related issues during pre-silicon and post-silicon phases
• Mentor senior engineers and architects to enhance architectural thinking across the organization

• Employees at Rivian are often offered comprehensive health, dental, and vision insurance, a 401(k) with company match, ESPP and potential RSU grants, performance bonuses, and generous time off including paid parental and sick leave. Perks can include 24/7 mental-health coaching and therapy, Hinge Health for Anthem enrollees, tuition assistance and professional development, plus on-site food and a wide range of employee discounts on items like computers, mobile phones, home loans, and pet care.
