Scale AI's Scale Labs is hiring a research scientist for safety post-training. The work involves designing post-training pipelines to study how training choices affect model safety, robustness and alignment, developing interpretability-informed evaluations of unsafe or deceptive behavior, and translating findings into safety standards and benchmarks alongside policymakers and engineers. The posting asks for RLHF, DPO or GRPO experience, published ML research, and at least three years on complex ML problems. Interviews cover practical ML prototyping and debugging; the posting says there are no LeetCode-style questions.
