Anthropic is hiring a research engineer or research scientist to work on large-scale ML systems for safer, steerable AI. The role spans research and engineering: improving cluster reliability, raising training throughput, running experiments, and building tools for faster iteration. Projects may include attention mechanism optimization, comparing Transformer variants, dataset preparation, distributed jobs across thousands of GPUs, fault tolerance, and attention visualization. Candidates need significant software engineering experience, strong collaboration, and comfort with ambiguity. The posting is evergreen, and hybrid work generally requires at least 25% office time.
