Principal / Senior GPU Software Performance Engineer - Training at Scale

THE ROLE

We train large models across multiGPU clusters. Your charter is to make training materially faster and cheaper by leading kernel‑level performance engineering—from math kernels and fused epilogues to cluster‑level throughput—partnering with researchers, framework teams, and infrastructure.

KEY RESPONSIBILITIES

• Own kernel performance : Design, implement, and land high‑impact HIP / C++ kernels (e.g., attention, layernorm, softmax, GEMM / epilogues, fused pointwise) that are wavesize portable and optimized for LDS, caches, and MFMA units.
• Lead profiling & tuning : Build repeatable workflows with timelines, hardware counters, and roofline analysis; remove memory bottlenecks; tune launch geometry / occupancy; validate speedups with A / B harnesses.
• Drive fusion & algorithmic improvements : Identify profitable fusions, tiling strategies, vectorized I / O, shared‑memory / scratchpad layouts, asynchronous pipelines, and warp / wave‑level collectives—while maintaining numerical stability.
• Influence frameworks & libraries : Upstream or extend performance‑critical ops in PyTorch / JAX / XLA / Triton; evaluate and integrate vendor math libraries; guide compiler / codegen choices for target architectures.
• Scale beyond one GPU : Optimize P2P and collective comms, overlap compute / comm, and improve data / pipeline / tensor parallelism throughput across nodes.
• Benchmarking & SLOs : Define and own KPIs (throughput, time to train, $ / step, energy / step); maintain dashboards, perf CI gates, and regression triage.
• Technical leadership : Mentor senior engineers, set coding / performance standards, lead performance "war rooms," and partner with silicon / vendor teams on microarchitecture‑aware optimizations.
• Quality & reliability : Build reproducible perf harnesses, deterministic test modes, and documentation / playbooks so improvements persist release‑over‑release.
