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.
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.

You’ll work closely with colleagues across the firm to expand our relationships with onshore counterparties, including exchanges, brokers/market intermediaries and other service providers.

We are looking to hire an ASIC Physical Design Engineer to help us design, test, and deploy advanced hardware. As part of our Ultra Low Latency team, you'll have the opportunity to collaborate with people in areas across the firm, including trading, networking, and research infrastructure.
This isn't a traditional PD role. We're a small team where everyone works across the chip design process, and we expect our PD engineers to lead with physical design expertise but think like chip designers. You should be comfortable owning a PD flow end-to-end, but also able to read and write RTL and reason about design decisions that cross the front-end/back-end boundary.
If you've spent your career exclusively in PD, this probably isn't the right fit— but if you've worked across the stack, either because you started as an RTL designer and moved into PD, or because you were on a smaller team where you had to wear multiple hats, we'd love to talk.
We're big believers in the ability of tools to improve the productivity, reliability, and day-to-day joy of hardware engineering. That's why we created Hardcaml, a hardware development toolchain embedded in OCaml. We don't expect you to know OCaml (we'll teach you here), but we are looking for hardware engineers who are excited about the advantages that better tools can bring, and are willing to try new things as a result.

We are looking for a strategic thinker and skilled relationship builder to help us spearhead the planning and execution of a range of campus recruiting initiatives to attract outstanding interns and full-time employees across multiple business areas. The ideal candidate will excel at cultivating productive relationships with universities and student organizations, enthusiastically engage potential candidates, and think critically about our strategy to build this talent pipeline.
This role sits on our Early Careers Partnerships & Initiatives (ECPI) team, which is part of our broader global Campus Recruiting team. Our ECPI team is a highly supportive, collaborative and inventive group that spans our New York, London, Singapore, and Hong Kong offices.
The ECPI team owns a wide range of work — building and maintaining partnerships across academic levels and fields, planning and attending recruiting events, responding to immediate hiring priorities, and developing new initiatives from the ground up. The scope of this role will evolve based on your strengths and interests, but you should expect to move fluidly between strategic thinking and hands-on execution. On any given day, you might be shaping a new project's long-term direction and drafting the flyer to promote it, or digging into data to drive decision-making and confirming catering for an upcoming event. None of this happens in a silo — our best work comes from close collaboration with each other and teams across the firm. This will require finding solutions to big, interesting problems while also getting the little details right.
Like our Recruiting team at large, we believe that Jane Street's greatest assets are the people working around us. We love what we do, and perhaps more importantly, we love who we work with. This camaraderie fuels our passion for helping other teams at Jane Street find and hire great teammates of their own.

We're looking for a hands-on Cybersecurity Engineer to join our Cybersecurity team to strengthen the security posture of our applications, data, infrastructure, and processes.
The role combines both hands-on technical expertise to uncover and remediate vulnerabilities and people skills to partner with various teams across the firm, guide teams to analyze the security implications of design decisions and guide them to build security into their applications from the ground up.
The role will leverage your hands-on offensive background to identify threats and require you to dive deep into the technical details and help build tailored security solutions and develop creative approaches to complex challenges. This role will require practical threat modeling skills and the ability to translate security principles into concrete architectural improvements.
The role also involves having conversations with system owners who understand their applications but may not recognize potential exploits, partnering with them to identify and help resolve vulnerabilities, and balancing tradeoffs between security controls and business requirements.
As a member of the Cybersecurity team, you’ll join a skilled group of programmers and security experts dedicated to keeping the firm safe. Our work covers a wide range of topics, from software engineering and DevOps to risk analysis, security governance, and cyber awareness.

We are looking for a Data Engineer to turn messy, real-world datasets into reliable inputs for research and trading. Jane Street depends on data from a wide variety of sources to understand markets and the global economy—think world news, decades of weather patterns, deidentified credit card spending, or packet captures of stock exchange market data feeds. Clean, well-structured data is the difference between noise and a profitable trading signal.
You'll work closely with trading desks to identify Jane Street's data needs, evaluate datasets, and build pipelines that ingest and transform external data. You'll figure out what data means and how best to represent it. We build our own tools and software when needed, so you'll also help shape the systems you use every day.
This is a collaborative role, but you'll own your work from end to end. It requires a mix of engineering, data analysis, and product sense. You'll develop deep expertise in your data domains and use that understanding to decide what's worth building next.

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.

We will train you as if you’re joining our full-time team of IT Operations Engineers who are responsible for the support, configuration and operation of multiple systems across all of our technology stacks, including desktop engineering, network and various application platforms. You will help in a hands-on capacity as we make improvements to our office environment. This can include: responding to technology support requests, building and configuring Windows and Linux devices, supporting our Windows domain infrastructure, monitoring and supporting systems and helping with projects to optimize the way we work using tools like PowerShell.
Our IT interns are friendly and collaborative problem-solvers who enjoy helping people. They are able to troubleshoot in real time and engage with our end users, and are comfortable asking questions and admitting to mistakes. Our internships provide a great introduction to Jane Street and how we think about and solve problems across all teams. Often, successful interns have been invited to return for a full-time position after graduation.
We don’t expect you to have a background in finance or any other specific field—we’re more interested in how you think and learn than what you currently know. You should be:
Please note: Jane Street will provide flights to and from Hong Kong as well as accommodation throughout the entirety of the program.

We are looking for a Data Engineer to turn messy, real-world datasets into reliable inputs for research and trading. Jane Street depends on data from a wide variety of sources to understand markets and the global economy—think world news, decades of weather patterns, deidentified credit card spending, or packet captures of stock exchange market data feeds. Clean, well-structured data is the difference between noise and a profitable trading signal.
You'll work closely with trading desks to identify Jane Street's data needs, evaluate datasets, and build pipelines that ingest and transform external data. You'll figure out what data means and how best to represent it. We build our own tools and software when needed, so you'll also help shape the systems you use every day.
This is a collaborative role, but you'll own your work from end to end. It requires a mix of engineering, data analysis, and product sense. You'll develop deep expertise in your data domains and use that understanding to decide what's worth building next.

We are looking for a skilled analyst to join an expanding subgroup within our Finance team who can help us manage and improve many of our daily activities and processes. We don’t require any finance background or other particular experience—we care more about your curiosity, enthusiasm, and how you think and learn.
Members of our Financial Resource Management group, like the rest of Jane Street, are critical thinkers and problem solvers. We are ultimately responsible for managing the capital base the firm uses for trading. Much of what we do is constrained optimization – working with and providing costs to trading desks, managing our positions across providers subject to a vast set of limits and constraints, and strategizing how to support future growth. We’re also responsible for the modeling, monitoring, and operational processes that enable it.
In this role, you’ll work closely with colleagues within the group, with other teams throughout the firm, and with external counterparties - taking on responsibilities including:
There is ample room for growth in this position. As you gain experience in day-to-day operations, you'll independently make high-value, time-sensitive decisions, take increased responsibility for key processes, and design and implement long-term improvements. You’ll begin to think through how we prepare and respond to exceptional events and market volatility.
Note: You’ll be required to take the registration exams needed to obtain a series license upon starting.

We are looking for a FIX Onboarding and Connectivity Engineer to help us grow both our proprietary trading capabilities and client-facing trading business. This role involves working on the technical processes that enable our trading desks to access new products and exchanges, while also onboarding external clients to trade with Jane Street. You'll work closely with our trading teams to help them grow the business, and with our technology teams to build state-of-the-art connectivity systems.
Jane Street is a place where people come to learn new things (and to eventually teach others what they know). While we welcome experience with FIX and other order flow/electronic trading protocols, and value software engineering backgrounds, we're excited to teach you the specifics of our trading and technology.
The majority of your time will focus on onboarding and connectivity projects across both proprietary and client-facing trading. This will involve prioritising requests from the trading desks; working with our developers, infrastructure engineers, and external parties; and seeing the onboarding process all the way through to production. You will often find yourself bridging the gap between our clients, trading teams, and technology teams, requiring strong communication and coordination skills, but you will also need to be comfortable navigating the Unix command line and developing code of varying complexity to deliver these projects.
Through this work, we will expect you to keep a thoughtful and empathetic perspective on the way the team functions and collaborates as a whole, and to suggest ways we can improve and promote our best practices. We'll also look to you for opinions on how we approach and deliver project work, and how we should interface with other internal teams.
