Sr. Engineer, Performance Infrastructure (RISC-V)

Tenstorrent•Austin, TX

4d•$100,000 - $500,000•Hybrid

About The Position

Tenstorrent is a leader in AI technology, aiming to revolutionize performance, ease of use, and cost efficiency. The company is developing a high-performance RISC-V CPU and is seeking talented engineers to join their team. This specific role focuses on building and managing the performance infrastructure that supports the RISC-V Software and RISC-V Performance teams. The infrastructure includes benchmarking automation, data collection, and workload capture across various platforms (silicon, FPGA/emulation, performance models). The goal is to enable performance and software engineers to focus on analysis and optimization by automating experimental processes.

Requirements

Strong Linux systems engineering skills.
Comfortable managing lab machines, clusters, and hardware platforms.
Skilled in Python and shell scripting.
Solid CI (GitLab) experience.
Container experience.
Experienced automating at scale, including job scheduling, artifact management, databases, and dashboarding.
Curiosity about CPU performance is a plus.
Deep microarchitecture background is not required.

Nice To Haves

Identifying problems and developing solutions, with a bias toward owning the systems you build.
Enjoys building tools and optimizing workflows so other engineers can move faster.

Responsibilities

Build and maintain benchmarking automation and CI pipelines that run SPEC and real-world workloads across RISC-V silicon, FPGA/emulation platforms and performance models.
Own SimPoint generation and management infrastructure.
Build performance-data collection into databases, with dashboards and visualization tools on top, so trends and regressions are visible without manual effort.
Develop workload capture and replay tooling (QEMU- and CRIU-based checkpointing) so perf engineers can trace and analyze workloads reproducibly.
Collaborate closely with performance and software engineers on both teams to understand their flows and remove the infrastructure friction from them.
