Software Engineer, AI accelerator Runtime

Highlights

• Build low-level device runtime for OpenAI's custom AI accelerator silicon.
• Use cycle-accurate simulation to validate runtime before silicon exists.
• Turn compiled programs into efficient execution for frontier AI systems.

What they offer

• Equity

Ideal candidate

Low-level systems builder who thrives at the hardware-software boundary, obsessed with concurrency, performance and correctness, and energized by co-designing next-gen silicon with cross-functional teams.

Requirements

• Have strong low-level systems programming experience in C, C++, Rust, or comparable environments.
• Have built runtimes, drivers, firmware, operating-system components, accelerator software, or adjacent systems infrastructure.
• Understand concurrency, synchronization, asynchronous execution, queues, events, and memory-ordering semantics.
• Understand memory management, address spaces, DMA, caching, coherency, and hardware-software interfaces.
• Have hands-on experience with event-based, cycle-accurate simulators or closely related architectural and performance models.
• Can reason quantitatively about scheduling, latency, throughput, utilization, contention, and resource tradeoffs.
• Are skilled at debugging failures that span software abstractions, device interfaces, and hardware behavior.
• Work effectively across compiler, kernel, architecture, verification, firmware, and silicon teams.
