Job Summary: Drata is seeking a Senior Applied Research Engineer to drive the quality and effectiveness of our AI systems through rigorous experimentation, evaluation, and applied research. This is a research-focused role emphasizing experimentation and rigor over production engineering. You'll own the science behind how Drata's AI products retrieve, reason, and respond — and you'll work closely with AI and Software Engineers to turn validated approaches into production-ready systems. Drata's compliance platform is document-heavy: VRM Agent, AIQA, Trust Agent, policy-to-control mappers, and more all depend on high-quality information retrieval and reasoning. What you'll do: - Design and evaluate information access + reasoning strategies across RAG, agents, and classic ML: chunking, embedding models, hybrid search, metadata filtering, semantic routing - Prototype GenAI workflows (including agentic systems) that map and reason over compliance objects (controls ↔ risks ↔ requirements ↔ evidence) - Explore ML + probabilistic approaches where GenAI is not the best fit: classifiers, ranking models, graph/link prediction, calibration, and structured prediction - Build and maintain evaluation frameworks: golden datasets, automated quality metrics, regression detection - Implement and tune ranking/reranking systems: cross-encoders, LLM-based rerankers, learning-to-rank, custom scoring functions - Run experiments to validate hypotheses and quantify improvements before production rollout - Debug failure modes and build error taxonomies across retrieval, reasoning, and generation - Collaborate with AI and Software Engineers to hand off validated approaches for productionization - Stay current on applied research in RAG, agents, LLM evaluation, and relevance modeling; bring innovations into the product What you'll bring: - 5+ years of experience in applied research, data science, or ML with a focus on NLP, information retrieval, or knowledge systems - 2+ years of hands-on experience building or contributing to production AI/ML systems - Strong foundation in information retrieval: dense and sparse retrieval, embedding models, search relevance - Experience with RAG systems: chunking strategies, vector databases, retrieval optimization - Proficiency in evaluation methodology: metrics design, golden dataset creation, A/B testing, statistical significance - Strong Python skills and comfort with notebook-driven research wo
