[Remote] AI Researcher — Inference Optimization

Note: The job is a remote job and is open to candidates in USA. FeatherlessAI is 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. The role involves improving latency, throughput, and cost efficiency across real-world production environments by developing techniques to optimize inference performance and collaborating with engineering teams to deploy optimized pipelines. 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 Skills • 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 • 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) Company Overview • We enable serverless inference via our GPU orchestration and model load-balancing system. It was founded in 2023, and is headquartered in San Francisco, California, USA, with a workforce of 2-10 employees. Its website is https://featherless.ai/. Company H1B Sponsorship • Featherless AI has a track record of offering H1B sponsorships, with 1 in 2025. Please note that this does not guarantee sponsorship for this specific role.
