AI Research Engineer - Datadog AI Research (DAIR)

As an AI Research Engineer, you will partner with scientists to turn research ideas into production-ready systems, building data, tooling, and infrastructure for rapid iteration on Observability Foundation Models, SRE Autonomous Agents, and Production Code Repair Agents. You will design and operate datasets, training and evaluation pipelines, and benchmarks to support reliable, scalable experimentation. You will implement models, run experiments at scale, and profile for reliability, performance, and cost. You will orchestrate distributed training and distributed RL with Ray, including scheduling, scaling, and failure recovery. You will make the research stack observable and reproducible, establish automated benchmarks and regression tests, and document results. You will collaborate with Research Scientists, Product, and Engineering to turn prototypes into reliable services and contribute high-quality code, documentation, and open-source artifacts.
