About the Job

Requirements

  • Currently preparing for a BAC+5-level program in AI, Data Science, natural language processing, or machine learning, and in the final year of the program.
  • Knowledge of natural language processing.
  • Knowledge of deep learning and neural networks.
  • Knowledge of large language models and generation.
  • Knowledge of information retrieval, including BM25 and ranking.
  • Knowledge of evaluation and alignment, including metrics and grounding.

Responsibilities

  • Design and improve method prompts and templates, creating question-and-answer templates for definition (materials/specifications), manufacturing (process plans/instruction sheets), and manufacturers (qualification/capabilities).
  • Deploy and optimize a retrieval-augmented generation pipeline, including PDF, Word, and Excel ingestion; chunking; indexing; filtered retrieval by product, material, or process; and generation with citations.
  • Simplify information from heterogeneous documents, including OCR for scans, parsing instruction sheets, and extracting parameters, tolerances, requirements, and process-plan sections.
  • Normalize information into structured schemas for the methods data model, producing usable outputs such as JSON or internal formats for materials, processes, steps, checks, acceptance criteria, and manufacturer requirements.
  • Build an AI-assisted manufacturer reference database by extracting capabilities, qualifications, and machine inventories from documents, enabling semi-automatic updates and filtering rules by process or material.
  • Evaluate quality through benchmarking and iteration by creating a business test set, measuring accuracy, relevance, and rate of sourced responses, and proposing improvements to retrieval, prompts, chunking, and rules.
