About the Position

We are looking for a Data Engineer who can help us understand, clean, manage, and share the data that guides our trading. At Jane Street, having a thorough and accurate understanding of data is at the core of the work we do.

Using our mix of in-house and open-source software, you will analyse datasets gathered from a variety of sources, checking for anomalies, matching formats and symbologies, automating ETL processes, and generally making it easier for our traders to generate valuable insights.

You should be excited about digging deep into datasets and explaining your findings to different types of colleagues, working collaboratively with traders and software engineers.

While prior experience with financial data would be nice, we don’t expect you to have a finance background. We’re happy to hire talented engineers and teach them what they need to know.

About You

Jane Street serves institutional clients through trading and liquidity services alongside proprietary trading activity.

Palpable Score

87
/ 100
Jane Street offers unusually strong early-career access through recurring internships and multiple entry programs, backed by clear pay transparency and high compensation. The strongest signals are hands-on training, mentorship, and real project ownership for interns and new grads, plus benefits that reduce early-career financial stress. The main limiter is that Jane Street does not publish cohort outcomes like promotion rates or internship-to-full-time conversion rates, so outcomes scoring relies on indirect public signals.
