  • Partner with senior leaders and business stakeholders to understand processes, shape hypotheses, clarify requirements, and translate business needs into actionable analytical approaches.
  • Guide research design, model evaluation, validation, monitoring, and responsible-use practices, providing expert judgment on model performance, stability, governance, and appropriate application.
  • Build reusable tools, frameworks, and shared resources that improve modeling efficiency, consistency, scalability, and quality across the analytics and AI community.
  • Prepare and deliver clear, insightful presentations with recommended actions, communicating complex analytical findings and business implications to leadership audiences.
  • Mentor and develop junior AI scientists and analysts through technical guidance, coaching, and knowledge sharing.
  • Participate in special projects and perform other duties as assigned.
Qualifications
  • Hands-on experience building LLM-powered applications, such as retrieval-augmented generation pipelines, prompt engineering workflows, fine-tuning approaches, or agentic frameworks including LangChain, LangGraph, or Google ADK.
  • Related work experience in data science, AI, machine learning, or analytical roles, with strong experience applying statistical and machine learning methods to business problems.
  • Experience with large language models, generative AI, knowledge graphs, and modern AI evaluation practices.
  • Proficiency in Python and machine learning frameworks such as TensorFlow, PyTorch, or Scikit-learn.
  • Experience with cloud platforms, such as AWS, and associated AI services, data platforms, and deployment tools.

Questions you could be asked

  1. How do you structure and test a prompt to get consistent output from a language model?
  2. How would you design a retrieval step so the model answers from real data instead of guessing?
  3. Walk me through fine-tuning a model: what data did you use, and how did you check the result?
  4. How do you decide that one model's output is better than another's for a given task?
  5. Walk me through how you've used LangChain in your day-to-day work.

Adapt your resume

  • List these exact terms on your resume: Prompt Engineering, RAG, Fine Tuning, AI Evaluation, and LangChain. An applicant tracking system matches the wording, not the idea.
  • Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
  • Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
