AI Researcher — Inference Optimization

RemoteFull-timePosted Jan 23, 2026

Job description

ROLE OVERVIEW We are seeking an AI Researcher with deep experience in inference optimization to design, evaluate, and deploy high-performance inference systems for large-scale machine learning models. You will work at the intersection of model architecture, systems engineering, and hardware-aware optimization, improving latency, throughput, and cost efficiency across real-world production environments.

KEY RESPONSIBILITIES

  • Research and develop techniques to optimize inference performance for large neural networks.
  • Improve latency, throughput, memory efficiency, and cost per inference.
  • Design and evaluate model-level optimizations (quantization, pruning, KV-cache optimization, architecture-aware simplifications).
  • Implement systems-level optimizations (dynamic batching, kernel fusion, multi-GPU inference, prefill vs decode optimization).
  • Benchmark inference workloads across hardware accelerators.
  • Collaborate with engineering teams to deploy optimized inference pipelines.
  • Translate research insights into production-ready improvements. REQUIRED QUALIFICATIONS
  • Strong background in machine learning, deep learning, or AI systems.
  • Hands-on experience optimizing inference for large-scale models.
  • Proficiency in Python and modern ML frameworks (e.g., PyTorch).
  • Experience with inference tooling (e.g., Triton, TensorRT, vLLM, ONNX Runtime).
  • Ability to design experiments and communicate results clearly. PREFERRED / NICE-TO-HAVE QUALIFICATIONS
  • Experience deploying production inference systems at scale.
  • Familiarity with distributed and multi-GPU inference.
  • Experience contributing to open-source ML or inference frameworks.
  • Authorship or co-authorship of peer-reviewed research papers in machine learning, systems, or related fields.
  • Experience working close to hardware (CUDA, ROCm, profiling tools). WHAT SUCCESS LOOKS LIKE
  • Measurable gains in latency, throughput, and cost efficiency.
  • Optimized inference systems running reliably in production.
  • Research ideas successfully translated into deployable systems.
  • Clear benchmarks and documentation that inform product decisions. RELEVANT RESEARCH AREAS (BONUS)
  • Long-context inference optimization
  • Speculative decoding
  • KV-cache compression and paging
  • Efficient decoding strategies
  • Hardware-aware inference design
