Midcore CPU Performance Architect

Tenstorrent is looking for a CPU Architect to take the lead on the design and optimization of the Midcore Unit (MC) in our high-performance, out-of-order RISC-V CPUs. This is a hands-on architecture role with real impact—you’ll be shaping the performance-critical instruction scheduling and execution units in the CPU. You'll work alongside some of the industry's best minds in high-performance computing and CPU micro-architecture.

This role is remote, based out of the United States.

We welcome candidates at various experience levels for this role. During the interview process, candidates will be assessed for the appropriate level, and offers will align with that level, which may differ from the one in this posting.

Who You Are

• You have a strong grasp of CPU microarchitecture fundamentals, especially around instruction scheduling, register files, scalar and vector execution, and optimizing instruction execution latencies.
• You have worked with performance simulation tools like Gem5 or SimpleScalar and are comfortable analyzing system bottlenecks and tuning performance.
• You’re collaborative, organized, and enjoy bridging architectural ideas with hands-on modeling and analysis.
• Familiarity with HDLs (Verilog, VHDL) and low-level C/C++ programming is a plus—not required, but helpful in collaborating with design and software teams

What We Need

• Drive the architecture and microarchitecture of the midcore unit for our out-of-order RISC-V CPUs.
• Model, simulate, and evaluate mid-core performance and PPA (power, performance, area) tradeoffs, including novel cross-unit instruction scheduling and execution techniques.
• Propose and prototype new approaches to optimize scheduling and execution paths and improve instruction/data throughput.
• Collaborate with software, RTL, and performance modeling teams to close the loop on real-world performance.

What You Will Learn

• How to architect high-throughput, low-latency general purpose, AI, and HPC workloads that scale across chiplets and cores.
• How to model and optimize CPU behavior across different instruction-mix patterns and workloads.
• How Tenstorrent blends RISC-V extensibility with custom microarchitecture to push boundaries in high-performance CPU design.
• How cutting-edge CPU teams deliver innovative performance features from architecture spec to implementation and validation.
