Anthropic is hiring a machine learning engineer for its pretraining team in San Francisco, on a hybrid schedule. The work covers scaling training infrastructure, optimizing distributed training pipelines, and developing new methods for training large language models efficiently and safely. The engineer runs experiments alongside researchers and ships improvements to the company's Claude models. The posting asks for machine learning engineering work on large-scale distributed training rather than product or applied work, and places the role directly on the pretraining effort behind the company's own models. Compensation is listed at 220,000 to 320,000 USD.
