Jane Street

Jane Street dev Ian Henry first went looking for a better strace back in 2017 and never found one. In our latest blog post, he shares strace-ui, the interactive terminal UI he finally built, and explains how Bonsai_term and AI coding agents have kicked off a "TUI renaissance" at Jane Street, where a handful of new terminal apps now get built every day.

We're looking forward to attending #OSDI in Seattle next week and discussing our latest work in systems design. Stop by our table and meet the team!

We're headed to Seoul for #ICML2026! Deep learning is a major driver of our trading at Jane Street, and we're excited to connect with others working on hard problems across different modalities. Visit our booth to chat with the team.

In this episode of Signals & Threads, EPFL professor and Jane Street visiting researcher Nate Foster joins Ron to explore what happens when you bring a software mindset to network engineering. They discuss programming language theory and formal methods for software-defined networks, the return (or not) of multicast, how ML workloads are reshaping the networking layer, and Jane Street's success pairing BGP with a more declarative specification language. https://lnkd.in/ebmFbfaZ

After a fantastic first event in Sydney earlier this year, we're bringing female and gender-diverse STEM students together again with IMC, Jane Street, Optiver, Susquehanna, and VivCourt. Designed for first- and second-year university students interested in trading, technology, and quantitative research, the event will offer insight into: ● Pathways into the trading industry  ● What different roles actually look like day-to-day  ● Skills and mindsets that set high performers apart  ● Common misconceptions about trading The evening will feature a panel discussion with live Q&A and a chance to chat directly with women working across several leading trading firms. If you've ever wondered what a career in trading is really like, we'd love to see you there. Sign-ups close July 17: https://lnkd.in/g6mVBsgq #WomenInTrading #STEMCareers #TradingCareers

What does it take to keep trading systems running smoothly across stock markets around the world? In a recent #TechTalk, Jane Street production engineer Mark Doss walks through the day-to-day work of monitoring and operating those systems, where every message matters and a few extra seconds of alerting can show up directly in the P&L. Along the way, he digs into what happens when things go wrong, and why getting traders and engineers to speak each other's language is often the fastest path to resolution.

At Jane Street, our flat structure means decisions are most often made by people closest to the work, so great ideas move from conversation to production without getting stuck in red tape. Hear from our recruiters how that plays out in their work.

We're headed to Salt Lake City for #STOC2026! Many of the most interesting problems at Jane Street trace back to questions and ideas in algorithms and the broader theory of computing — from optimization and sampling to scheduling to game theory. Excited to spend the week with the TCS community.

We're excited to be at #PLDI2026 in Boulder next week! Our teams work closely with the PL community, from contributing to the OCaml compiler to applying PL ideas across our trading and research systems. Looking forward to catching up with the PLDI community — stop by our booth to chat with the team!

After taking a walk through our Texas data center, Dwarkesh Patel sat down with Ron Minsky and Dan Pontecorvo for an in-depth conversation on GPUs, trading horizons, and hiring. Hear what they had to say: https://lnkd.in/e-gnczye
