  • Lead roadshows and demos to advocate for Gen AI tools and drive cultural change across the enterprise.

Requirements

  • Master’s or Ph.D. in Computer Science, Data Science, Machine Learning, or related fields.
  • 5+ years of experience in applied ML, AI development, or advanced data science roles.
  • Hands-on experience building and deploying LLM-based agents, RAG pipelines, and multimodal Gen AI systems.
  • Proficiency in Python and Gen AI frameworks
  • Strong understanding of agent orchestration frameworks (LangGraph, LangChain, AutoGPT, or equivalent).
  • Demonstrated expertise in benchmarking, A/B testing, and model monitoring for AI systems.
  • Experience developing and maintaining prompt engineering standards and frameworks.
  • Ability to evaluate and optimize model performance across different LLMs and architectures.
  • Strong communication and collaboration skills across product, engineering, and business teams.
  • Proven track record of mentoring team members and driving innovation in AI workflows.
  • Familiarity with internal experimentation, observability, or AI governance tools is a plus.
  • Contributions to open-source projects, research publications, or AI community initiatives is a plus.
