Hiring: Researcher, Alignment CoT Monitorability Company: OpenAI Location: San Francisco, CA Job Posted Time: 2026-09-02 18:00:16 Employment Type: Hybrid Target Skills & Keywords : HBase, Make, Move, OpenAPI, Reinforcement Learning About the job Required Skills: •We’re looking for a researcher with strong empirical ML expertise and a deep interest in model behavior, alignment, or interpretability. Direct chain-of-thought interpretability experience is welcome but not required; strong candidates may come from broader interpretability, alignment, model training, or investigative model-behavior work. •As a researcher on the Alignment team, you will design and run experiments that improve our understanding of model monitorability. You will investigate how training interventions across the model-development pipeline influence whether reasoning remains legible, build evaluations that make those questions measurable, and help translate findings into practical oversight and training recommendations. You may also help develop new monitoring models or methods and apply them to OpenAI’s largest training runs. •This role is especially well suited for someone who can move from an ambiguous model-behavior question to a concrete experimental setup: formulate the hypothesis, build the evaluation or intervention, run the experiment, analyze the result, and decide what the evidence supports. This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees. •In This Role, You Will •Design and run empirical studies of chain-of-thought monitorability across frontier reasoning models and training settings. •Build evaluations that measure whether monitors can reliably predict properties of interest, including high-stakes forms of misbehavior. •Investigate how pre-training, synthetic data, mid-training, post-training, reinforcement learning, and other interventions improve or degrade monitorability. •Analyze model behavior and turn observations from monitoring into hypotheses, experiments, and recommendations. •Translate research findings into practical monitoring and oversight approaches that can inform real training runs. •Collaborate with researchers and engineers across model training, alignment evaluations, monitoring, and frontier-risk work. •Produce externally publishable research when results advance the broader science of alignment.
