About the Role

The AI Engineering Intern will contribute to the design and development of generative AI applications and agentic solutions for Bain’s clients. You will gain hands-on exposure to the full AI development lifecycle, from early prototyping through to production-ready deployment, in a learning-first role with mentorship and increasing responsibility.

Responsibilities

  • Contribute to the design and development of GenAI applications using modern LLM stacks.
  • Support the implementation of AI pipelines and components, including Retrieval-Augmented Generation (RAG), fine-tuning, embedding generation, and hybrid retrieval strategies.
  • Assist in implementing tool use, function calling, and orchestration across AI workflows.
  • Assist in building agent capabilities including context engineering, memory and state management, orchestration, and tool integration.
  • Support model experimentation, evaluation design, and production deployment tasks.
  • Write clean, testable code and contribute to APIs and services through the full SDLC.
  • Contribute to evaluation and observability for GenAI systems.
  • Gain exposure to responsible AI practices across system design, including implementing guardrails and human-in-the-loop workflows.
  • Contribute to evaluation harnesses and reusable components.
  • Contribute to ML solutions end-to-end, including data preparation, model selection, training, validation, and performance analysis.
  • Apply appropriate ML methods spanning classical ML and deep learning.
  • Develop working knowledge of transformer fundamentals and LLM concepts.
  • Collaborate with product, engineering, and data science teammates to build well-structured, reliable AI systems.
  • Communicate clearly in working sessions, demos, and documentation.
  • Support client discussions and documentation as part of broader engagement teams.

Requirements

  • 0–2+ years of professional AI / ML engineering experience, or equivalent through internships, research, academic projects, or open-source contributions.
  • Currently pursuing or recently completed a bachelor’s, master’s, or PhD in CS, ML, AI, Data Science, Engineering, or a related quantitative field; or equivalent early-career experience.
  • Strong academic performance or demonstrated excellence through research, projects, internships, competitions, or open-source contributions.
  • Proficiency in Python and some experience building APIs or services, or comparable project-based experience.
  • Experience building complex, multi-stack generative AI programs from conception through production.
  • Exposure to retrieval and search systems and familiarity with structured and unstructured data stores.
  • Exposure to agentic patterns; hands-on experience preferred.
  • Strong engineering practices: testing, code review, version control, CI/CD, and performance profiling.
  • Excellent interpersonal and communication skills; interest in applying AI to real-world business problems in a client-facing environment.
  • Fluency in English and German is required.
