Senior IP Runtime Engineer - HW/SW Performance

Tenstorrent; Austin (TX); Hybrid; USD 100,000 - 500,000; Full time

Job summary

Tenstortort is seeking a seasoned C/C++ engineer to define and implement runtime software at the hardware/software boundary. The role focuses on initialization, scheduling, synchronization, and data movement across custom silicon IP, including processor cores and accelerators, with a strong emphasis on performance and reliability.

You will collaborate with hardware, firmware, compiler, and systems teams, tackle performance bottlenecks, and contribute hands-on through design, coding, and bring-up

Qualifications

• Expert in C or C++ with a track record of delivering complex, performance-critical systems.
• Experience 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.

Responsibilities

• Define the runtime architecture and implementation that controls execution, scheduling, synchronization, and resource management across Tenstortort'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.
