About the role
- As a Low-Level Software Engineer on Tenstorrent’s Low-Level Kernel (LLK) team, you’ll work at the intersection of software and AI hardware to build the primitives that power our workloads.
- LLKs sit directly on top of the ISA of Tenstorrent’s AI hardware and form the foundation for the software stack above them.
- You’ll tackle challenging problems in low-level programming, hardware-aware optimization, and performance engineering, with the opportunity to influence how our hardware is programmed and how efficiently AI workloads run.
Responsibilities
- Design and implement low-level kernels and software primitives that expose the capabilities of Tenstorrent AI hardware.
- Own complex performance optimization efforts, from profiling and identifying bottlenecks through implementation and validation.
- Develop software that enables efficient model bring-up and execution across Tenstorrent hardware.
- Partner with LLK subteams across performance, tools, compute, and architecture bring-up, as well as hardware and runtime teams.
- Drive improvements to the quality, performance, and capabilities of the low-level software stack.
Requirements
- Strong C/C++ engineer with significant experience building low-level, performance-critical software.
- Deep understanding of computer architecture and how software maps to hardware.
- Strong problem solver who can investigate complex performance and systems challenges and drive them to resolution.
- Comfortable working close to the hardware and making informed tradeoffs between performance, correctness, and maintainability.
- Effective technical collaborator who can work across software and hardware teams and influence technical decisions
Workplace
- This role is hybrid, based out of Toronto, Canada.
