Jane Street

Can you solve November's puzzle? Two random points, one red and one blue, are chosen uniformly and independently from the interior of a square. To ten decimal places (or the exact number, if you know it), what is the probability that there exists a point on the side of the square closest to the blue point that is equidistant to both the blue point and the red point? Visit our puzzle page to submit your solution. Note: Please hold off on sharing any puzzle theories or solutions until the end of the month when the challenge wraps up. We want to keep the puzzle fun and spoiler-free for everyone.

Jane Street is pleased to have led CoreWeave's latest equity raise. This marks our third investment and is a testament to CoreWeave's continued differentiation as the leading #AI hyperscaler. Read more:

In this episode of Signals & Threads, Sylvain and Ron go deep on how to make training more efficient, the subtle performance bugs #PyTorch lets you write, how to keep a hungry GPU well-fed, and the importance of reproducibility in training runs. They also discuss some of the unique challenges of doing #machinelearning in the world of trading, like the unusual size and shape of market data and the need to do inference at very low latencies. https://lnkd.in/emnkBYRH

Applications for the 2025 Jane Street Graduate Research Fellowship (GRF) are now open! The Fellowship supports exceptional doctoral students currently pursuing a PhD in computer science, mathematics, physics, or statistics enrolled at home institutions in the United States, United Kingdom, Canada, and Europe. Fellows receive full tuition and fees for the upcoming academic year and an additional stipend. We’re looking forward to supporting technically excellent PhD students who share our core values of intellectual curiosity and humility. Apply by November 21, 2024. https://lnkd.in/evR_C6pP

If you're attending EMNLP 2024, keep a lookout for our booth! Let's discuss innovative applications of NLP and computational linguistics. #EMNLP2024

We are delighted to announce our partnership with Jane Street to establish?Circles, a new initiative that will support groups of 3–6 researchers for four weeklong visits to the Simons Institute over two years to collaborate on an ambitious research project.

Counting down to #SREcon EMEA. The finance industry offers compelling challenges in the SRE space; visit our booth to talk about how Jane Street is at the forefront of solving them. See you in Dublin!

Over the course of a Jane Street internship, you’ll explore ways to approach and solve problems through challenging classes and interactive discussions, with endless opportunities to put those learnings to use. We offer opportunities in a variety of disciplines — quantitative trading, machine learning, software engineering, quantitative research, strategy and product, and more — which put you directly in the action, giving you the opportunity to collaborate and connect with Jane Streeters across teams in offices around the globe. Our internship applications for programs in New York, London and Hong Kong are open.

Our October #puzzle combines elements of #numbertheory and mathematical optimization in a unique variation of the knight's tour. Players must choose three numbers and guide a knight on two separate paths across a 6x6 grid, aiming for a specific score on each journey. The challenge lies in finding the smallest possible sum for the chosen numbers while meeting all the puzzle's conditions. Can you plan a perfect tour? Visit our puzzle page to view the full instructions and submit your solution!

Have you tuned in to the Signals & Threads tech podcast? Listen in on Jane Street's Ron Minsky as he has conversations with engineers working on everything from clock synchronization to reliable multicast, build systems to reconfigurable hardware. Get a peek at how Jane Street approaches problems, and how those ideas relate to tech more broadly. In a recent Signals & Threads episode, "From the Lab to the Trading Floor: Designing for Expert Users," we hear from Erin Murphy, a #UX designer at Jane Street who previously worked at NASA’s Jet Propulsion Laboratory! Ron and Erin discuss how beauty in design is more about utility than aesthetics, and explore ways to help engineers discover what their users really want. https://lnkd.in/eicQWhmw
