Jane Street works differently. As a liquidity provider and market maker, we trade on more than 200 trading venues across 45 countries and help form the backbone of global markets. Our approach is rooted in technology and rigorous quantitative analysis, but our success is driven by our people.

Our bright, beautiful offices in the heart of New York, London, Hong Kong, and Amsterdam are open and buzzing with conversation. We come from many backgrounds and encourage travel between offices to share perspectives. Some of our best ideas come from bumping into a visiting colleague at the office coffee bar.

Markets move fast. Staying competitive as we’ve grown has required constant invention—of new trading strategies, technology, and processes. We’ve found this is easier when you hire humble, kind people. They tend to help each other, and prioritize teamwork over titles.

We invest heavily in teaching and training. There’s a library and a classroom in every office, because deepening your understanding of something is considered real work. Guest lectures, classes, and conferences round out the intellectual exchanges that happen every day.

People grow into long careers at Jane Street because there are always new and interesting problems to solve, systems to build, and theories to test. More than twenty years after our founding, it still feels like we’re just getting started.

We work directly with colleagues in trading, technology, and operations to build and maintain systems with a firm-wide scope. Using feedback from other groups and our custom monitoring tools, we strive to resolve production issues quickly, perform comprehensive root-cause analyses, and integrate long-term fixes in a clean and robust way. We don't expect you to come in with deep experience - we're happy to hire smart problem solvers and teach them what they need to know. You’ll train alongside our more seasoned team members in a hands-on capacity, learning how we make tangible and immediate improvements to our infrastructure every day. About You Bachelor's degree in Computer Science, Software Engineering, or other technical discipline, or equivalent experience Experience managing/troubleshooting Linux systems in a home, work, or school environment Exposure to Linux environments through past experience in either software development, IT operations (Helpdesk, Technical Support, DevOps, etc.), or a similar field Interested in systems programming and administration and a desire to expand these skills Willing to learn OCaml, our programming language of choice (no prior experience with OCaml is required, though) Able to analyze and deconstruct technical problems Knowledgeable about operating system fundamentals, especially Linux Confident with the Unix command line and basic shell scripting Has a basic understanding of network protocols and can perform basic troubleshooting Comfortable with fundamental programming concepts Practical experience with modern Linux systems and systems programming concepts (e.g., C, sockets, virtual memory, process life cycle) is a plus Intermediate/advanced knowledge of troubleshooting tools and techniques (e.g., gdb, perf, DTrace, eBPF, or SystemTap) is a plus Knowledgeable, or at least interested in learning, about modern computer architecture techniques (e.g. familiarity with PCIe, NVMe, NUMA) Strong programmer (in any language) Fluent in English If you're a recruiting agency and want to partner with us, please reach out to&nbsp;agency-partnerships@janestreet.com.

About the position Our goals are to give you a real sense of what it’s like to work at Jane Street full time as a Machine Learning Researcher, and a truly unparalleled educational experience. You’ll work side by side with experienced ML Researchers on projects that we’ve selected for their combination of novel ML ideas and relevance to real-world systematic trading strategies. You'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.&nbsp; At Jane Street, the lines between research, technology, and trading are intentionally blurry. As our strategies grow more sophisticated, close collaboration is essential for continuing to push the boundaries of what’s possible. We work with petabytes of data, a computing cluster with hundreds of thousands of cores, and a growing GPU cluster containing 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. You’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’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. 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. About you 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 and a passion for solving interesting problems, we have a feeling you’ll fit right in. You should be: A PhD student or postdoc with practical experience working on empirical ML research problems&nbsp; Interested in applying logical and mathematical thinking to all kinds of problems Curious about the machine learning landscape and excited to apply state-of-the-art techniques drawn from many problem domains Fluent with a versatile set of models and tricks&nbsp; Able to rapidly implement and iterate on your ideas in Python and your favorite ML framework Eager to ask questions, admit mistakes, and learn new things Fluent in English If you’d like to learn more, you can read about our interview process and meet some of the team.

These will expose you to many of the dynamics we observe in real markets, illustrate the role that we play in making markets more efficient, and help build intuition for how we think about both trading and collaborating. At Jane Street, the lines between research, technology, and trading are intentionally blurry. As our strategies grow more sophisticated, close collaboration is essential for allowing us to continue pushing the boundaries of what’s possible. We work with petabytes of data, a computing cluster with hundreds of thousands of cores, and a growing GPU cluster containing thousands of high-end GPUs. We don’t believe in “one-size-fits-all” modelling solutions; we are open to and excited about applying all different types of statistical and ML techniques, from linear models to deep learning, depending on what best fits a given problem. Quantitative trading interns also have the opportunity to participate in one “elective” based on your interests. Electives consist of targeted classes and immersive activities, and are designed to give you a deeper and more nuanced look into one of the many aspects of what quantitative trading can look like at Jane Street: Machine Learning, Modelling, and Data Science You'll learn how Jane Street applies advanced machine learning and statistical techniques to&nbsp;make models and predictions using large datasets of both real and simulated market data. You'll learn how to train and use a variety of ML models, and gain an understanding of the differences between textbook machine learning and its application to noisy and complex financial data. Algorithmic Trading and Market Microstructure You'll learn the end-to-end process of developing an algorithmic trading strategy. You'll analyse market data to develop a tradable fair value and implement a trading strategy in Python. Your algorithmic strategy will connect directly to simulated markets with different market structures, and you will learn how to optimise your strategy given the unique attributes of each market. You will discover how various market dynamics affect strategy behaviour and learn how real-world trading differs from simulation. Trading Strategy and Scenarios You’ll be introduced to a rotating set of new trading scenarios inspired by real events on a particular trading desk. You’ll work in teams on multiple mock trading sessions related to each scenario and use the time between sessions to refine your strategies, write recaps, and hear how the story played out in real life from our seasoned full-time traders who lived through it. About You 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. We’re more interested in how you think and learn than what you currently know. You should be: A strong quantitative thinker (no specific degree or major is required) A clear and effective verbal and written communicator Someone who enjoys working collaboratively on a team Eager to ask questions, admit mistakes, and learn new things Fluent in English A profitable trading strategy is only as strong as the technology it runs on, and we consider ourselves as much a technology company as a trading firm. General programming experience is a plus, but knowing a particular programming language is not required. If you’d like to learn more, you can read about our interview process and meet some of the team.

<h3>About the Position</h3>
We're looking for a Cybersecurity Engineer to help us mature our vulnerability management program. You'll join our Cybersecurity team, a skilled group of programmers and security experts dedicated to keeping the firm safe.&nbsp;
Vulnerability management is the focus of this role, but it doesn't tell the whole story—we want a well-rounded engineer whose knowledge spans the different facets of cybersecurity, because that broader perspective is what lets you reason well about real risk and where to spend effort.
Vulnerability management is a well-established part of how we keep the firm safe, and as we grow, we're continuing to invest in it, with a particular focus on automation and on scaling the program to keep pace with an expanding environment.
This is a hands-on, build-heavy role. We want someone with a strong technical foundation who isn't afraid to build something themselves, who has good judgment about what actually matters, and who can explain the "why" behind a risk and its mitigation. Manual triage doesn't scale at our size, so you'll lean on automation, including AI tooling paired with good judgment, knowing where it helps and when we need a human in the loop.
Your work will also include:&nbsp;
<ul>
<li>Supporting and improving the vulnerability management lifecycle end to end, from discovery and validation through triage, assignment, remediation tracking, and verification</li>
<li>Reviewing new findings from automated scanning tools, threat intel, and security advisories, then prioritizing based on real exploitability and exposure rather than severity score alone, so we act on what genuinely matters</li>
<li>Validating and deduplicating findings across sources, confirming whether an affected product or component is actually present, and routing work to the team that owns the fix</li>
<li>Measuring scanning coverage and data quality and knowing what isn't being scanned, where scans are stale, and where authentication is failing, rather than assuming coverage is complete</li>
<li>Driving automation across vulnerability management tooling and processes</li>
<li>Broadening scanning coverage across asset classes, including evaluating and migrating scanning platforms as needed</li>
<li>Bringing software inventory and SBOM data into the picture so we can answer where a vulnerable component is used across our software, not just what's running on a given host</li>
<li>Building dashboards and metrics that measure coverage, SLAs, and progress</li>
</ul>
<h3>About You</h3>
<ul>
<li>You automate rather than do things by hand, keep your code and configs in version control by default, work comfortably under code review, and care about leaving things maintainable</li>
<li>You’re comfortable working with data, querying and shaping it, and building and debugging the data pipelines and integrations that stitch messy, inconsistent inputs into something dependable</li>
<li>You have hands-on vulnerability management experience in a substantial environment, including experience with an automated scanning platform such as Rapid7, Tenable, or Qualys, and an understanding of how scanning, asset inventory, and remediation tracking fit together</li>
<li>You’re a measured responder who reasons about trade-offs and context, understands threat modeling, and knows not every finding deserves the same urgency</li>
<li>You follow cybersecurity developments and can tell the difference between an interesting hack and what matters day-to-day</li>
<li>You understand and practice good personal cybersecurity hygiene, and can talk to others about it</li>
<li>You’re a clear communicator across audiences, who writes things down so others can follow</li>
<li>You have a positive and collaborative attitude; You understand that a key component of cybersecurity is bringing others along with you on the journey</li>
</ul>

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&nbsp;course of your internship, you will explore ways to approach and solve exciting problems within&nbsp;your field of interest through fun and challenging classes, interactive sessions, and group&nbsp;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&nbsp;on real-world projects we actually need done. When you’re not working on your project, you will&nbsp;have plenty of time to use our office amenities, physical and virtual educational resources,&nbsp;attend guest speakers and social events, and engage with the parts of our work that excite you&nbsp;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. Learn more about Jane Street’s internship program here.

Front End Software Engineer

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.
