OpenAI's Training team in London builds the large language models behind its research and products. The researcher will design, prototype and scale new architectures, run and analyze experiments, debug and optimize model and compute performance, and contribute to training and inference infrastructure. The posting asks for hands-on empirical work on LLM architectures, model inference, and state-of-the-art transformer efficiency, including contributions to major training runs. Distinctive: the work spans both strengthening a baseline and long-term architecture bets; relocation support and a three-day office week.
