Hiring: Machine Learning Researcher, LLM Post-Training Company: Thurn Partners Location: New York, United States Job Posted Time: 2026-09-16 18:21:19 Employment Type: Full-time / Remote Target Skills & Keywords : Fine-tuning, LLM, Machine Learning, PyTorch, Python About the job Required Skills: •Post-train and domain-adapt state-of-the-art large language models on proprietary financial text and tabular data at petabyte scale. •Own alignment and fine-tuning end to end: SFT, DPO, RLHF and parameter-efficient methods (LoRA/PEFT), plus the training infrastructure behind them. •Build rigorous evaluation pipelines for reasoning, quantitative accuracy and strict factuality, in a setting where model outputs inform real decisions within days. •Work at the metal when it matters: GPU memory management, mixed precision (FP16/BF16), quantisation and parallelisation strategies across a very large cluster. •Collaborate closely with a small group of researchers and a dedicated research platform team, with a compute-to-researcher ratio few laboratories anywhere can match. •Hands-on experience post-training large language models at a research lab, big tech group or applied AI team shipping real systems. •Comprehensive expertise in transformer architectures and modern alignment techniques. •Strong Python with PyTorch or JAX, and the low-level GPU fluency to exploit large clusters efficiently. Qualifications: •PhD or equivalent research depth preferred; publications welcome, shipped results count just as much. Compensation: •$750,000 - $6,000,000 / year Interested candidates, please apply directly through the job posting on company's career page or try via AI auto apply on this platform.
