About the Role

As a Data Engineering intern at Jane Street, you will learn how to turn messy, real-world data into reliable foundations for research and trading. You'll write Python, SQL, and OCaml; use open-source tools and proprietary software; and work with structured and unstructured data including world news, weather patterns, credit card spending, and market data feeds.

During the internship, you'll take on two real projects: exploring unfamiliar datasets, understanding their contents, and explaining your findings. You'll write code to ingest and transform data and monitor its quality, while being mentored by full-time Data Engineers and learning from data users.

Requirements

  • Curious about what data means, not just how to move it from one place to another
  • Comfortable manipulating data in Python, SQL, R, or similar
  • You don't need to be a polished software engineer, but you should be able to turn an idea into working code
  • An analytical and logical thinker: able to investigate something new, ask good questions, and come to sound conclusions
  • Humble and eager to ask questions, admit mistakes, and learn new things
  • Courteous, reliable, and organized
  • A clear verbal and written communicator
