You&#39;ll work side by side with experienced ML Researchers on projects that we&#39;ve selected for their combination of novel ML ideas and relevance to real-world systematic trading strategies. You&#39;ll learn how we think about markets through challenging classes and activities, and practice using established methods alongside our own unique twists to train practical models.</p>\n<p>At Jane Street, the lines between research, technology, and trading are intentionally blurry, and you’ll have access to petabytes of data, a computing cluster with hundreds of thousands of cores, and a growing GPU cluster containing tens of thousands of high-end GPUs. Trading poses unusual challenges—large models and nonstationary datasets in a competitive multi-agent environment—that force us to search for novel techniques.</p>\n<p>You&#39;ll spend the bulk of your internship working closely with full-time machine learning researchers on projects drawn from their own work. You might conduct an end-to-end study of an unexplored dataset, try a new modeling paradigm for a thorny problem, or consider blue-sky approaches that we&#39;re still trying to figure out. The problems we work on rarely have clean, definitive answers, and they often require insights from colleagues across the firm with different areas of expertise. Depending on the day, you might be diving deep into market data, tuning hyperparameters, debugging training issues, or analyzing the predictions your model makes.</p>\n<p>Note that given the IP-sensitive nature of machine learning research at Jane Street, it is unlikely that any research findings associated with the internship will be suitable for outside academic publication.</p>\n<p><strong>About you</strong></p>\n<p>If you&#39;ve never thought about a career in finance, you&#39;re in good company.

It&#39;s a broad role, and no two Linux Engineers look exactly alike. Our work spans on-prem and cloud infrastructure, every major pillar (compute, storage, networking), and every layer of the stack from the physical hardware to workload orchestration. You should expect to work in some (but not necessarily all) of these areas, and to go genuinely deep in a few.</p>\n<p>That might mean:</p>\n<ul>\n<li>Building the in-house tools and systems that make up our platform, or integrating mainstream (often open-source) technologies so they feel native to our infrastructure</li>\n<li>Acting as one of the firm&#39;s Linux experts, and teaching other engineers specialist skills like systems debugging</li>\n<li>Automating our own work, because it makes us faster and more reliable (and we think it&#39;s fun)</li>\n<li>Diagnosing and resolving production issues in real time, often under time pressure</li>\n<li>Carrying out scheduled changes to the platform, like upgrades, migrations, capacity changes, and rollouts, planned meticulously and executed carefully</li>\n</ul>\n<p>The problem space runs from the physical to the abstract: datacenter provisioning and orchestration, kernels and drivers delivered through Nix and RPMs, production and research storage at scale, cloud that integrates cleanly with our on-prem platform, and, in partnership with our IT and Network Engineering colleagues, Linux desktops and how our hosts participate in the network.</p>\n<p>We see Linux Engineering and Software Engineering as two ends of a spectrum, and plenty of people could do either job well. Linux Engineering is likely the better fit if you treat Linux itself as your problem space: you like working close to the operating system, you want to look after production infrastructure, and you&#39;re happy spending more of your time in a consulting capacity than a typical developer would. (Compared with kernel development, the emphasis flips: you&#39;d rarely develop the kernel itself, though targeted patches happen, and you&#39;d spend far more time running production infrastructure.) We&#39;re hiring for both roles and are happy to advise you on which might fit best.</p>\n<p>We don&#39;t expect you to come in with deep experience; we&#39;re happy to hire smart problem-solvers and teach them what they need to know.

Members of this group are hard-working Systems Engineers, Administrators and Programmers, tasked with maintaining and improving the platform that powers Jane Street&#39;s production trading systems. Our mix of in-house and open source software allows you to investigate and innovate at every level. On any given day, you could be debugging kernel performance, developing management tools, or resolving production issues in real time.

Establishing a culture of great docs is especially important as we grow.</li>\n<li><strong>Building tools that support documentation.</strong> So much documentation is auto-generated by our systems, whether as error messages, logs, automated emails, or library docstrings. Getting your hands dirty hacking on documentation-adjacent tools will help not just to a first order, but will also make your other writing more effective.</li>\n<li><strong>Training material. </strong>We have a ton of programs that new and experienced hires go through, ranging from an OCaml Bootcamp to Dev Teach-ins that expose students to interesting technical problems from around the company. Part of the job is to make these better and mint more of them where valuable.</li>\n<li><strong>Writing longer pieces. </strong>We need more tutorials and overviews on a variety of topics. We have an internal developer handbook that we’re writing, with a backlog of chapters—each one an opportunity to dive deep into some part of our stack. But there’s also a lot of external writing to be done, for instance on our blog, our programming podcast, for conferences, recruiting events, and more.</li>\n</ul>\n<p>In terms of skills, we want someone who is both an excellent writer and good enough at programming to navigate our codebase, work through our tutorials, and write up examples.
