  • Define customer value, quality, reliability, safety, engagement, and business-impact success metrics for AI product experiences.
  • Design and operationalize LLM evaluation frameworks across prototyping, model and prompt iteration, feature development, launch validation, and post-launch monitoring.
  • Build evaluation methodologies for LLM-based, agentic, retrieval-augmented, and multimodal systems involving text, image, document, audio, video, and interaction-based experiences.
  • Develop offline experimentation and evaluation pipelines for models, prompts, system designs, retrieval strategies, grounding, tool use, and end-to-end product behavior.
  • Partner with engineering and product leadership on science priorities, product strategy, roadmap decisions, customer needs, and execution plans.
  • Collaborate with software engineers to build reliable, scalable, observable, maintainable, and production-quality AI systems using MLOps practices.
  • Run hypothesis-driven experiments, interpret results, and recommend product or technical actions.
  • Establish evaluation scorecards, regression testing, guardrail metrics, launch criteria, and responsible AI decision frameworks.
  • Mentor scientists and engineers, influence cross-team AI practices, and communicate findings, risks, tradeoffs, and recommendations to technical and non-technical stakeholders.

  • Hands-on experience with large language models, prompt engineering, retrieval-augmented generation, agents, tool use, model comparison, failure analysis, and evaluation-driven iteration.
  • Deep experience with LLM evaluation, including dataset creation, annotation strategies, automated and human evaluation, benchmark design, regression testing, launch criteria, and production monitoring.
  • Experience designing offline experiments and using results to guide model, system, and product decisions.
  • Experience evaluating multimodal AI systems or experiences involving multiple input and output modalities.
  • Understanding of product success metrics and ability to translate customer and business goals into measurable scientific and technical objectives.
  • Solid software engineering skills and experience collaborating with engineers on production-quality AI systems.
