Description

You will develop, evaluate, and democratize foundation models including embeddings, pre-trained LLMs, and fine-tuned language models. You'll build embedding pipelines, design evaluation frameworks, drive models to production, and guide business stakeholders in integrating these models into their workflows.

Requirements

  • Bachelor’s degree in Data Science, ML, Computer Science, or a related discipline
  • 3+ years of hands-on experience in data science or machine learning roles
  • 3+ years’ experience building in Python using big data tools (e.g. Hadoop, Databricks)
  • Hands-on experience building processes incorporating LLMs, embeddings, or related model architecture
  • Experience applying embeddings within AI projects and machine learning applications
  • Track record of shipping, measuring, and maintaining machine learning models in production
  • Exceptional communication skills with ability to explain complex technical concepts to non-technical audiences
  • Experience in stakeholder management, technical documentation creation, and cross-functional collaboration

Responsibilities

  • Develop and optimize embedding pipelines for vector search, retrieval-augmented generation (RAG), and downstream ML applications.
  • Conduct rigorous model testing, evaluation, and validation against quality metrics, performance benchmarks, and reliability standards prior to release.
  • Design and execute proof of concepts to demonstrate feasibility for specific business problems.
  • Build and maintain automated testing frameworks for model performance, data quality, and pipeline integrity.
  • Collaborate with MLE/Researchers/Engineers to develop, fine-tune, and deploy foundation models.
  • Perform exploratory data analysis (EDA), feature engineering, and data preprocessing to support model development.
  • Develop and maintain Jupyter notebooks, scripts, and workflows for reproducible experimentation and analysis.
  • Contribute to building and maintenance of code packages, APIs, hosted applications, and other foundation model delivery mechanisms.
  • Troubleshoot integration challenges and provide technical guidance for model integrations.
  • Guide business stakeholders, data science and engineering teams through adoption and integration of foundation embedding and generative AI models.
  • Create documentation, user guides, and best practices for internal model adoption and usage.
  • Serve as a liaison between the Foundation Models team and business stakeholders, gathering feedback to inform the development roadmap.
