Scale AI is hiring research scientists and engineers for the evaluation pod within its GenAI Research Organization. The work involves diagnosing how frontier language and multimodal models fail — capability gaps, reasoning errors, robustness and alignment — and building benchmarks and evaluation methods to measure capabilities. The posting asks for a PhD or master's in computer science or a related field, post-training experience with SFT, RLHF or reward modelling, and published conference research. Customer-facing experience is preferred. Roles are on-site in San Francisco, Seattle or New York.
