Datadog is hiring a Senior Applied Scientist for GenSim, within AI Platform's evaluation and experimentation pillar. This first applied science role owns methodology for simulated environments and post-training data. Work includes measuring data correctness, representativeness, and difficulty; closing realism gaps; and building production systems used in training and evaluation. The posting asks for a PhD/MS or equivalent, six-plus years, hands-on LLM/agent post-training data, agent evaluation, Python, and distributed systems. Distinctive: the team lacks applied science support, and SRE simulation is not well solved publicly.
