Experience designing controlled experiments or ablation studies to understand effect of data on model quality Experience building agentic or multi-agent, tool-using LLM systems and human-in-the-loop workflows, calibrating judges against human labels, and mitigating failure modes Strong software engineering skills, with 5+ years in Python, workflow orchestration (Airflow), cloud platforms (AWS, GCP), distributed data processing frameworks (Spark, Ray, or similar) at large scale Publication record or open-source contributions in NLP, computer vision, or generative AI is a plus Familiarity with privacy-preserving data techniques (e.g., differential privacy, on-device data constraints) is a plus. Day to day, that means building distributed pipelines that clean, deduplicate, and enrich massive multi-modal datasets; standing up synthetic data generation pipelines with LLM-based generators, validators, and judges; and engineering agentic workflows - multi-step, tool-using LLM systems - that scale human judgment across far more data than a human team could review directly.
