Staff Engineer, SoC RTL Design

Job Description

Tenstorrent is seeking a Staff Engineer to focus on Fabric and Memory Subsystem microarchitecture and RTL for high-performance SOCs. The candidate will work on a server-class SoC fabric that supports cutting-edge data center designs. This is a hybrid role based out of Toronto (ON), Ottawa (ON), Boston (MA), or Austin (TX).Tenstorrent welcomes candidates at various experience levels and will assess them during the interview process to align offers accordingly.Responsibilities:

• Design and develop the Fabric and Memory subsystems from scratch for a high-performance CPU.
• Create RTL implementations in Verilog using industry-standard tools and open-source infrastructure.
• Collaborate with cross-functional teams to ensure seamless delivery of the Fabric and Memory subsystems.
• Evaluate and integrate 3rd-party IP components into the subsystem to meet performance and design goals.
• Optimize power, performance, and area (PPA) by working closely with performance modeling, DV, and physical design engineers.
• Conduct experiments with RTL and analyze synthesis, timing, and power results to improve design quality.
• Debug complex RTL/logic issues across different design hierarchies in both pre-silicon and post-silicon environments.
• Enhance RTL design infrastructure and tools to streamline development and ensure consistency across projects.

Experience & Qualifications:

• BS/MS/PhD in EE/ECE/CE/CS with 5+ years of experience in Fabric or Memory subsystem design.
• Extensive experience with CPU and GPU fabrics, including cache coherence protocols and memory ordering models.
• Strong understanding of interconnect topologies and protocols such as CHI, AXI, ACE, TileLink.
• Proven ability to tightly couple memory subsystems with CPU cores, optimizing data paths, bandwidth, and latency.
• Experience evaluating PPA trade-offs and working with synthesis, timing, and power tools.
• Hands-on experience with hardware description languages (Verilog, SystemVerilog) and simulators like VCS, NC, and Verilator.
• Expertise in microarchitecture definition and specification development for complex memory systems.
• Strong debugging and problem-solving skills across hierarchical levels in both pre- and post-silicon environments.

Tenstorrent offers:

• A highly competitive compensation package and benefits.
