Junior Data Scientist

Summary

Build and deploy LLM systems for banking, evaluating models with offline tests and A/B trials while fine-tuning with Python and vLLM.

What you'll do:

  • Build and ship LLM systems and workflows to production, where real bankers and customers use them
  • Learn to evaluate AI properly: offline evals, A/B tests, live monitoring
  • Work hands-on with Python, vLLM, prompt optimization, and fine-tuning
  • Work alongside experienced teams in Product, Risk, and Compliance to apply data science techniques to real-world banking scenarios, including credit risk and regulatory compliance.

We’re looking for curious and eager-to-learn candidates who are:

  • Fresh graduate (Bachelor's or Master's) in a quantitative field: Statistics, Computer Science, Math, Engineering, Physics
  • Strong Python fundamentals
  • Have experience on building something with LLMs (through Thesis, internship, side project, or hackathon) and can explain the concept and its objective in a simple way

Bonus points (not required):

  • Exposure to vLLM, LoRA/QLoRA fine-tuning, or prompt optimization frameworks like GEPA
  • Interest in financial data and regulation
