Your application will only be received by Recruiter if submitted via above link. 


STEP 2:

Kindly scroll to the bottom of this page and complete the short VinUni Tracking Form.

What you'll do

  • Build an agent quality evaluation pipeline: an automated benchmark measuring response accuracy, grounding, and hallucination rate

  • Run retrieval tuning experiments, improving chunking, embedding, and ranking strategies validated against the benchmark

  • Build a working GraphRAG/memory prototype for cross-session memory persistence

  • Document experiments and findings so the core team can adopt them directly


We're looking for someone who

  • Solid Python and software engineering fundamentals (final-year student or fresh graduate level)

  • Familiarity with LLMs, prompt engineering, and loop engineering; hands-on exposure to RAG concepts is a strong plus

  • Basic data engineering skills — building pipelines, working with structured and unstructured data (e.g. JSON)

  • Experience with LangChain/LlamaIndex, graph databases, or evaluation frameworks (e.g. Ragas, DeepEval) is a strong plus

  • Self-directed learner, comfortable with ambiguity, with an experimentation mindset — always willing to try a new retrieval or memory approach rather than sticking to the first one that works

  • Good written English for documentation, since findings need to be picked up by the core engineering team, including honest reporting of benchmark results, regressions included

  • Genuinely into how AI agents actually work, not just running pre-built tutorials

  • Currently pursuing or recently completed a Bachelor's or Master's degree in Computer Science, Artificial Intelligence, Data Science, or a related field (final-year student or fresh graduate)


Why you'll love interning here

  • Real projects. Real ownership. No coffee runs. No photocopying. You'll contribute to work that actually matters.

  • Learn from experts. Work alongside experienced professionals who genuinely enjoy mentoring.

  • Grow faster. Receive regular feedback, ask questions freely, and learn through doing.

  • Meet amazing people. Collaborate across teams and build meaningful connections.

  • Get paid while you learn. Competitive monthly internship allowance.

  • Experience global SaaS. Discover how a fast-growing tech company builds products used by teams around the world.
