Applied Scientist II

Job Title: Applied Scientist II Company: Microsoft Job Category: Machine Learning Roles & Responsibilities: Overview The Purview AI Classification team builds advanced AI capabilities to identify and classify sensitive information at enterprise scale, with a strong focus on Named Entity Recognition (NER) and rigorous AI evaluation. We develop and improve ML/NLP models for complex entity recognition scenarios and build evaluation methodologies to systematically measure accuracy, precision, recall, robustness, and model improvements across diverse datasets and real\-world conditions. The Applied Scientist will drive experimentation, dataset and error analysis, model evaluation, and iterative improvements to NER and classification quality, while partnering closely with engineering and product teams to translate scientific advances into scalable capabilities within Microsoft Purview. Responsibilities * Design, develop, and deploy AI/ML systems end\-to\-end, covering data ingestion, feature engineering, model training, evaluation, and production integration. * Build and optimize Generative AI and LLM\-based systems, including agentic workflows, prompt engineering, RAG, and fine\-tuning. * Write production\-grade code in Python, C\#, etc., with emphasis on scalability, performance, security, testability, and maintainability. * Partner with engineering, product management, and applied science teams to translate customer/business requirements into robust technical solutions. * Ship and operate large\-scale AI services in the cloud, owning reliability, latency, throughput, accuracy, and cost efficiency. * Define and execute model evaluation strategies, including offline experimentation, online monitoring, drift detection, bias analysis, and feedback loops. * Implement MLOps practices, including model CI/CD, versioning, rollout strategies, observability, and live\-site monitoring. \- * Apply Responsible AI principles covering privacy, security, explainability, fairness, and compliance throughout development and deployment. * Stay current with advances in GenAI, LLM frameworks, and ML infrastructure, and evaluate their applicability to enterprise security scenarios.
