Requirements

• Strong Python and PyTorch engineering skills
• Hands-on experience deploying or optimizing LLM, VLM, or high-throughput transformer inference systems
• Practical knowledge of at least one modern inference stack such as vLLM, SGLang, TensorRT-LLM, Triton Inference Server, NVIDIA Dynamo, Ray Serve, KServe, or equivalent internal systems
• Strong understanding of transformer inference bottlenecks, including KV cache, attention, memory bandwidth, batching, parallelism, and long-context serving
• Ability to reason quantitatively about latency, throughput, quality, utilization, and cost tradeoffs
• Strong communication skills and ability to collaborate with research, kernel, infrastructure, product, and customer teams

Nice to Haves

• Experience with quantization-aware training, post-training quantization, FP8, INT8, INT4, NVFP4, MXFP4, AWQ, GPTQ, SmoothQuant, or related techniques
• Experience with distillation, speculative decoding, EAGLE, Medusa, multi-token prediction, or other inference acceleration methods
• Experience with agentic workloads, including tool calling, structured outputs, streaming APIs, high concurrency, and multi-step orchestration
• CUDA or Triton familiarity, even if the role is not primarily a kernel-engineering role
• Open-source contributions to vLLM, SGLang, TensorRT-LLM, FlashInfer, LMCache, PyTorch, Triton, Ray, KServe, or related projects

What You'll Be Doing

• Own optimization work for specific model families, customer endpoints, or serving backends
• Run engine comparisons and recommend practical serving configurations for specific workloads
• Debug model quality or performance regressions during production rollouts

• Deploy, configure, benchmark, and extend inference engines
• Build and productionize model-compression workflows
• Implement or integrate speculative decoding, draft-model approaches, KV-cache optimization, and more
• Build reproducible benchmark harnesses
• Partner with GPU kernel engineers and platform engineers to diagnose bottlenecks
• Write clear design docs, performance reports, rollout plans, and customer-facing technical explanations
