Cohere is hiring a Member of Technical Staff for post-training. The person will write scalable training software, run post-training to reach state-of-the-art model performance, work with agentic and code teams, and develop SFT and reinforcement-learning techniques on large compute and data infrastructure. The posting asks for strong software engineering, Python, ML frameworks such as JAX or PyTorch, and experience with distributed training at scale. Work is hybrid across several offices or remote-friendly. Distinctive: high compute-to-engineer ratio and no hard split between engineering and research.
