    Production Engineer

    - New York City

    About the Position We are hiring Production Engineers in our New York office. Jane Street Production Engineers are software developers who spend time both developing software and also providing high-quality support for software systems that are critical to Jane Street's trading business. Many of our Production Engineers are embedded in various software teams; others are in standalone teams. In both situations we work alongside application developers with a common goal of creating and running great software systems. As a firm we are big believers in functional programming, and use OCaml as our primary development language. Production Engineers play an essential role interacting with a wide variety of departments and functions at Jane Street. We solve real-time issues and make a firm-wide impact. We take ownership of the architecture and design of systems that monitor and support the firm's trading. We also design and develop the tools that we use, and it feels great to be able to shape these tools and then enjoy the improvements. If you'd like to learn more, you can read about Production Engineering at Jane Street. How is a Production Engineer role different from a generic Software Engineering role? As Production Engineers: * We split our time between OCaml software development project work and a support rotation, in which we actively resolve live issues in Jane Street's critical systems * We are curious and eager to learn about a number of different systems and how they fit together. This gives us a breadth of knowledge and opportunities to collaborate with many other dev and business teams across the firm * We spend less time in total coding (due to the support rotation), and are interrupted more often, and we enjoy adding value to Jane Street in this way * We get satisfaction from helping others, enabling good trades, and getting to the bottom of complex and urgent production issues About You We don't expect you to have a background in functional programming, finance, or any other specific field-we're looking for smart software developers who enjoy solving interesting problems. We're more interested in how you think and learn than just what you currently know. You should be: * A strong programmer with a love for technology; able to write and read code well * An intellectually curious person who is motivated, collaborative, and eager to learn * An excellent communicator, able to be clear and calm during production incidents If you're a recruiting agency and want to partner with us, please reach out to agency-partnerships@janestreet.com.

    Quantitative Researcher

    Apply Now
    About the Position We are looking for Quantitative Researchers to hel... Read More
    About the Position We are looking for Quantitative Researchers to help us build models, strategies, and systems that price and trade financial instruments. You'll apply your experience in experiment design, dataset generation, time series analysis, feature engineering, and model building to financial datasets, while collaborating with colleagues who will challenge and refine your approach. At Jane Street, our researchers, engineers, and traders sit a few feet away from each other and work together to train models, architect systems, and run trading strategies. We work with petabytes of data and a growing GPU cluster containing tens of thousands of high-end GPUs. Depending on the day, we might be diving deep into market data, tuning hyperparameters, debugging distributed training performance, or studying how our model likes to trade in production. We don't believe in "one-size-fits-all" modeling solutions; we are open to and excited about applying all different types of statistical and machine learning techniques, from linear models to deep learning, depending on what best fits a given problem. The most successful researchers will be driven by a curiosity for how their contributions fit into the larger picture of our trading operations, and how to adapt their findings into actionable strategies. 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: * Able to apply logical and mathematical thinking to all kinds of problems * Intellectually curious; eager to ask questions, admit mistakes, and learn new things * A strong programmer who's comfortable with Python * An open-minded thinker and precise communicator who enjoys collaborating with colleagues from a wide range of backgrounds and areas of expertise Most candidates will have experience with data science or machine learning, though your approach to problem-solving and capacity to learn will weigh just as heavily as your existing expertise. Having a PhD or other research experience is a plus. If you're a recruiting agency and want to partner with us, please reach out to agency-partnerships@janestreet.com. Read Less

    About the Position We are looking for a Statistical Arbitrage Researc... Read More
    About the Position We are looking for a Statistical Arbitrage Research Analyst who is excited to apply rigorous math and statistical methods to analyze a variety of input datasets to create novel alpha-focused trading strategies for Jane Street. Your work has the potential to span across any and all liquid asset classes, including, but not limited to, U.S. and global equities, equity and fixed income futures, FX, and corporate bonds. Ideally, you will have previous experience working in a buy-side or sell-side financial firm with some combination of asset price returns data, non-returns-based traditional data, and "alternative" data sets. However, if you are an economist or data scientist in a different field (such as tech) we're open to teaching you what you need to know to thrive in this role. We are looking for someone who is eager to dig deep into the details of data sets to assess quality and consider outliers, dimensionality, feature engineering, causality, aligning dates across datasets, and more. You'll help us stay vigilant in our efforts to find and correct errors or mistakes in code, which inevitably happen - though we expect this role to involve as much time delving into the lovely messiness and complexity of data as it will on advanced statistical modeling. The problems we work on rarely have clean, definitive answers, and they often require insights from people across the firm with different areas of expertise. We find that we make the most progress when team members collaborate and communicate fluidly. Your success in this role will depend on your ability to balance expertise and intellectual rigor with an open mind to a variety of techniques and modes of thinking. We don't believe in "one-size-fits-all" solutions; we are open to and excited about applying all different types of mathematical and statistical techniques, depending on what best fits a given problem. Progress takes place at different tempos on our team depending on the project, so you'll need to be comfortable embracing both large leaps and incremental steps forward. About You * 2-6 years of professional experience working in a data-rich environment in quantitative research * Team player with a highly collaborative mindset; communicate clearly and often and enjoy discussing research ideas and results in depth * Open to a variety of techniques and modes of thinking * Humble about what you do and don't know; willing to admit mistakes * Enjoy learning new skills and teaching others what you know * Able to write code and analyze large datasets * Experienced with statistical and ML modeling * Knowledge of Python preferred, but not required * Background knowledge of financial markets is a plus If you're a recruiting agency and want to partner with us, please reach out to agency-partnerships@janestreet.com.

    About the Position Jane Street is hard at work building OxCaml, a branch of OCaml with a variety of extensions to support performance engineering. But designing and implementing the language is only half the battle: we need our developers to understand its nuances and program in OxCaml as experts. That's where you come in. We're looking for an experienced, skilled educator to help us develop materials and deliver courses to teach engineers at Jane Street how to use OxCaml effectively. You would work broadly across our internal educational programs, from expanding our OCaml Bootcamp for new hires to use OxCaml to developing specific tutorials to level-up experienced developers that need OxCaml's most advanced features. This is a unique opportunity to work hand-in-hand with a language's designers and implementers to develop its educational component. You would be part of the team within Jane Street building the next generation of OxCaml. Here's what we're looking for: * We want someone who is a skilled, effective, and experienced teacher. Part of that means being an effective writer and presenter. * The job demands an understanding of our technology stack, and the best way to build that understanding is by doing. That means we want someone who is good at writing code, and is excited to spend a significant fraction of their time doing so. * Part of the job is going to be directly teaching and developing curricula. But an equally important part is helping other people involved in teaching grow their skills, so we want someone who is good at mentoring other budding teachers. We're excited to talk to people who have experience teaching CS topics in a university setting, as well as people who have spent time teaching technical topics in industrial settings. Read Less
