ML Silicon Performance LeadPosted today$287K–$485K

The opportunity

OpenAI’s Hardware organization develops AI-native silicon and system-level solutions for the unique demands of advanced AI workloads. Building on efforts like Jalapeño, the team is developing future generations of AI-native silicon and tightly integrated systems to power the next generation of frontier models.

What you'll do

  • Drive hardware/software co-design across ML research, compiler, and silicon: teams, jointly shaping kernel implementations and hardware capabilities to meet workload performance and efficiency goals.

  • Partner with ML research to translate model and workload needs into kernel: performance targets and compute, memory capacity, and bandwidth requirements, feeding hardware constraints and opportunities back into model and algorithm choices.

  • Map and optimize ML kernels for architecture, using insights from data: movement, memory hierarchy, and execution efficiency to guide both software improvements and hardware design.

  • Co-design support for new data structures and quantization formats across: kernels, compilers, and silicon, balancing model quality, numerical behavior, performance, power, and implementation cost.

  • Define and help develop specialized acceleration IP, working with compiler: and silicon partners to determine the right division of functionality across software, instructions, and dedicated hardware.

  • Drive ML performance modeling and simulation with the compiler team to: compare hardware/software design options, expose bottlenecks, and quantify end-to-end benefits on representative workloads.

What they're looking for

  • Partner with the Silicon Architecture lead and silicon team to specify and: validate new IP, using kernel and simulation results to refine requirements and prioritize architectural improvements.
  • Have deep experience with ML accelerator architecture and how compute: resources, memory systems, and data movement shape workload performance.
  • Can translate model-level behavior into concrete kernel requirements and hardware design decisions.
  • Have built or used accelerator performance models and simulators, and know: how to validate their assumptions and interpret their limitations.
