About the role
- You will work at the hardware/software boundary to define how those hardware blocks are initialized, coordinated, and used by the runtime.
- You will determine how workloads are dispatched, scheduled, synchronized, and executed across the accelerator, while solving complex performance problems through implementation, bring-up, and debugging.
Responsibilities
- Define the runtime architecture and implementation that controls execution, scheduling, synchronization, and resource management across Tenstorrent’s custom processor, accelerator, memory, and data-movement IP.
- Build low-level runtime components that initialize hardware IP, dispatch work to processor and accelerator engines, coordinate dependencies, and manage resources efficiently.
- Design runtime interfaces and data-movement paths that make memory access, synchronization, and execution efficient and predictable.
- Analyze bottlenecks across the runtime and hardware/software stack, then drive improvements in latency, throughput, scalability, and reliability.
- Influence the direction of the runtime stack, engage directly with customers and field-facing teams, and translate real-world workload needs into runtime improvements while remaining hands-on with design, coding, performance analysis, bring-up, and debugging.
Requirements
- An expert C or C++ engineer with a track record of designing and delivering complex, performance-critical systems.
- Experienced working close to hardware in low-level, embedded, bare-metal, or accelerator environments and translating hardware specifications into reliable software behavior.
- Strong in runtime fundamentals, including command execution, scheduling, synchronization, memory movement, resource management, and parallelism.
- Skilled at debugging and optimizing systems end-to-end, especially at the hardware/software boundary.
- A technical leader who collaborates effectively across hardware, firmware, compiler, and systems teams and mentors other engineers.
Workplace
- This role is hybrid and based in Toronto, ON or Austin, TX.
