We're looking for Software Engineers who want to help us design and build the systems and tools that run the firm. You'll find Software Engineers in all parts of Jane Street, solving real problems in critical areas ranging from trading desks to our accounting team, as well as building foundational infrastructure, whether that means implementing network monitoring or risk models. We are big believers in functional programming and, using OCaml, a statically -typed functional programming language, as our primary tool. More recently, Python has become a vital part of Jane Street's research and trading work, acting as the go-to language for data analysis, visualization, and machine learning. Beyond our own environment, we also recognize the value of open source software, leveraging it in our daily work and releasing over a million lines of our own code as open source. We're also always looking for ways to expand open source projects, and provide ongoing support to things like Mercurial, the OCaml compiler, and the OPAM package manager. That said, we're interested in talented engineers with experience in any language-most of us came in with little to no practical experience in OCaml before we joined. If you'd like to learn more, you can read about our interview process and meet some of our newest hires. About You We don't expect you to have a background in functional programming, OCaml, Python, finance, or any other specific field-we're looking for smart programmers who enjoy solving interesting problems. We're more interested in how you think and learn than what you currently know.

We're looking for a software engineer who is passionate about front-end development, user-interface design, and typed functional programming. You would take part in the design and implementation of our next-generation of browser-based tools for operating our trading infrastructure. We're building for expert users, which means we want to maintain a high UX bar, and at the same time create tools that are flexible and powerful enough to satisfy the needs of deeply engaged users. Beyond working on the individual tools, we want someone who can find opportunities to create libraries and abstractions that capture common interaction idioms, and to sharpen our development practices and firm-wide approach to UI development. We're looking to add someone with a particular mix of skills and experience: A strong background in web technologies, including browser fundamentals like CSS and the DOM, and an understanding of the principles of UI frameworks like Vue, Angular, React, and Flutter. Practical experience building sophisticated UIs in the browser. We're looking for someone who loves the detailed polishing that's needed to build elegant and highly usable UIs. An interest in and appreciation of typed functional programming as an approach to UI construction. Experience with languages like Elm, ReasonML, Purescript, and Typescript is a plus. (we don't expect experience in OCaml in particular.) The role will provide opportunities to work in multiple parts of the stack, including front-ends, back-ends, middleware, and databases. The job will also involve working closely with traders and other end-users to better understand their needs.

We're always hiring software engineers for all of our offices. Technology is at the core of how we approach our work, and engineers are intimately involved in every area of the business. We are big believers in functional programming and use OCaml, a statically typed functional programming language, as our primary tool. More recently, Python has become a vital part of Jane Street's research and trading work, acting as the go-to language for data analysis, visualization, and machine learning. We also believe in the value of open source software, using it in our daily work and releasing over a million lines of our own code as open source.

There's no specific checklist; we use software to approach a variety of problems, so we're interested in everything from machine learning to systems administration to programming language design Strong interpersonal skills. Software engineering at Jane Street is highly collaborative, and we are looking for people who can work effectively in small, close-knit teams We don't expect you to have experience with functional programming, OCaml, Python, or finance; we're happy to hire talented engineers and teach them what they need to know. If you'd like to get an idea of what we cover in our software engineering interview process, you can visit our interview prep page. If you're a recruiting agency and want to partner with us, please reach out to ********************************** .

We're looking to hire a programmer-who-writes, or a writer-who-codes. Here are the kinds of things we'd like to have this person work on: Documentation. We've always believed that developers should spend time and effort documenting their own code, but at the same time, a great writer with a feel for the technology can raise the level of quality in a way that few developers can. Establishing a culture of great docs is especially important as we grow. Building tools that support documentation. 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. Training material. 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. Writing longer pieces. 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. 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. You might spend meaningful time embedded as an engineer on one of our projects, just to understand how we write software. But experience with functional programming, expressive type systems, OCaml, or finance are all unnecessary-we're happy to teach you about these things here. If you're a recruiting agency and want to partner with us, please reach out to ********************************** .

About the program Our goal is to give you a real sense of what it's like to work at Jane Street full time. Over the course of your internship, you will explore ways to approach and solve exciting problems within your field of interest through fun and challenging classes, interactive sessions, and group discussions - and then you will have the chance to put those lessons to practical use. As an intern, you are paired with full-time employees who act as mentors, collaborating with you on real-world projects we actually need done. When you're not working on your project, you will have plenty of time to use our office amenities, physical and virtual educational resources, attend guest speakers and social events, and engage with the parts of our work that excite you the most. If you've never thought about a career in finance, you're in good company. Many of us were in the same position before working here. If you have a curious mind, a collaborative spirit, and a passion for solving interesting problems, we have a feeling you'll fit right in. About the Position As a Software Engineering intern, you'll learn how we use OCaml (our primary development language) in our day to day work, and gain exposure to the libraries and tools that are foundational to our internal systems. Some teams also use Python, so depending on the project, you might do some work with Python as well. During the internship, you'll work on one or two projects, closely mentored by full-time software engineers. Mentors design intern projects based on their team's current needs and are heavily invested in helping interns build maintainable, high-quality software that is intended to reach production. The projects you will work on are as varied and diverse as those full-timers work on, covering a wide range of problems, from high performance trading systems to programming language design and everything in between. If you'd like to learn more, you can read about our interview and team placement processes and get a sense of what our most recent intern projects looked like! About You We don't expect you to have a background in finance, OCaml, functional programming, or any other specific field-we're looking for smart people who enjoy solving interesting problems. We're more interested in how you think and learn than what you currently know. You should be: A top-notch programmer with a love for technology Intellectually curious, collaborative, and eager to learn Humble and unafraid to ask questions and admit mistakes If you're a recruiting agency and want to partner with us, please reach out to **********************************.

We're looking for Software Engineers who want to help us design and build the systems and tools that run the firm. You'll find Software Engineers in all parts of Jane Street, solving real problems in critical areas ranging from trading desks to our accounting team, as well as building foundational infrastructure, whether that means implementing network monitoring or risk models. We are big believers in functional programming and, using OCaml, a statically -typed functional programming language, as our primary tool. More recently, Python has become a vital part of Jane Street's research and trading work, acting as the go-to language for data analysis, visualization, and machine learning. Beyond our own environment, we also recognize the value of open source software, leveraging it in our daily work and releasing over a million lines of our own code as open source. We're also always looking for ways to expand open source projects, and provide ongoing support to things like Mercurial, the OCaml compiler, and the OPAM package manager. That said, we're interested in talented engineers with experience in any language-most of us came in with little to no practical experience in OCaml before we joined. If you'd like to learn more, you can read about our interview process and meet some of our newest hires.
